• Diagnostic Blood Test Venipuncture
  • Diagnostic Blood Test: Note: This test is capped and will not display results greater than 1500 ng/dL and 50 pg/mL, respectively. If you suspect you have elevated levels of Total or Free Testosterone we recommend using the uncapped test 'Total Testosterone (LC/MS) + Free Testosterone (Equilibrium Dialysis)', available here: https://marekhealth.com/product/free-testosterone-equilibrium-dialysis/ Total Testosterone, Standard (ECLIA) Free Testosterone (Direct) Testosterone is the primary sex hormone in men and plays important roles in women. Low testosterone levels may play a role in erectile dysfunction, decreased sex drive, muscle loss, weak bones, hair loss, fatigue, depression, memory problems, heart disease, and even earlier death. Optimal testosterone levels may lead to increased muscle mass and strength, higher endurance, enhanced libido, improved mood, lower cholesterol levels, increased bone mineral density, improved cognition and memory, better sleep, and a healthier metabolism. Total Testosterone test is a measure of the total amount of testosterone hormone in the blood. Free Testosterone is a measure of unbound testosterone that is available to the body’s tissues. Note: This test may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin. Cease biotin supplementation at least 72 hours prior to blood draw.
  • Diagnostic Blood Test: Total Cholesterol HDL Cholesterol LDL Cholesterol VLDL Cholesterol (calc) Triglycerides HDL/LDL Ratio Total Cholesterol measures the levels of both high-density lipoprotein (HDL) and low-density lipoprotein (LDL) in the blood. Cholesterol is necessary for creating new cells, producing hormones, making vitamin D, and creating bile (a fluid that aids in digestion). However, too much cholesterol may raise the risk of heart attack and stroke. High-density lipoprotein cholesterol (HDL-C) or “good” cholesterol is known to decrease the risk of heart attack and stroke by removing “bad” cholesterol from the blood vessels. HDL carries away other types of cholesterol to the liver in order to be flushed out of the body. Low-density lipoprotein cholesterol (LDL-C) or “bad” cholesterol builds up within the blood vessels. LDL levels help predict risk of heart disease and stroke and provide information about whether lifestyle changes or medications may improve heart health and overall wellness. Very low-density lipoprotein (VLDL) is similar to LDL however it mainly carries triglycerides. There is growing evidence that VLDL plays an important role in atherogenesis, in which plaques form on the interior walls of arteries, narrowing these passageways and restricting blood flow, which can lead to heart disease and increase the risk of stroke. Triglycerides are a type of fat located in the blood. High triglyceride levels may be a result eating more calories than are burned. Triglycerides can harden and thicken the walls of the arteries, increasing the ability of “bad” cholesterol to form plaques and raising the risk of heart disease. Note: Fasting is recommended for 12 hours prior to blood draw.
  • Diagnostic Blood Test: Estradiol, Standard (ECLIA) Important: In men, postmenopausal women, and adolescents we recommend the Estradiol, Sensitive (LC/MS) available here: https://marekhealth.com/product/estradiol-sensitive-lc-ms-ms/ Estradiol or E2 is the principle estrogen in men and women. Estradiol plays important roles in neuroprotection, fertility, metabolism, and anabolism. Imbalanced levels of Estradiol may be associated with erectile dysfunction, low libido, gynecomastia (the growth of breast tissue), hair loss, reduced muscle strength, or low energy levels. Note: This test may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin. Cease biotin supplementation at least 72 hours prior to blood draw.
  • Diagnostic Blood Test: White Blood Count (WBC) Red Blood Count (RBC) Hemoglobin (Hbg) Hematocrit (HCT) MCV MCH MCHC Red Cell Distribution Width (RDW) Platelets Neutrophils Neutrophils (Absolute) Lymphocytes Lymphocytes (Absolute) Neutrophil/Lymphocyte Ratio Monocytes Monocytes (Absolute) Eosinophils Eosinophils (Absolute) Basophils Basophils (Absolute) Immature Cells Immature Granulocytes Immature Granulocytes (Absolute) NRBC w/ Reflex for Immature Cells White blood cells (WBCs), or leukocytes, protect the body from infection. A low WBC count may signal various medical conditions, including autoimmune disorders, cancer, or problems with the liver, spleen, or bone marrow. A high WBC count may be caused by infection, inflammatory conditions, leukemia, or injury. Red blood cells (RBCs) carry oxygen to all of the tissues of the body. When the body has too few RBCs, it may be a sign of anemia, bone marrow conditions, vitamin deficiencies, or cancer. Too many RBCs may signal heart problems, kidney tumors, lung scarring, or bone marrow conditions. Hematocrit (HCT) indicates how much of the blood is made of red blood cells. HCT is dependent on the number and size of the red blood cells. Low levels of HCT may indicate various health conditions, while elevated HCT levels can increase the risk of heart attack or stroke. Hemoglobin is a protein found in red blood cells that helps transport oxygen to and remove carbon dioxide from the body’s tissues. Hemoglobin testing can provide information about hydration levels and the health of the blood cells. Conditions that affect the liver, heart, and lungs can also change hemoglobin levels. Mean corpuscular volume (MCV) describes the average size of each red blood cell. Normal-sized red blood cells are important for carrying oxygen around the body. Certain blood disorders, vitamin deficiencies, or other health conditions can alter the MCV. Mean corpuscular hemoglobin (MCH) is an indicator of how much hemoglobin (the protein that carries oxygen) is present within a single red blood cell. It describes how well oxygen is being transported to all of the body’s tissues. Changes in MCH may be due to blood disorders, nutritional deficiencies, kidney failure, or other conditions. Mean corpuscular hemoglobin concentration (MCHC) tests calculate levels of hemoglobin (the protein that carries oxygen) within a group of red blood cells and compare this with how big the cells are. This test can help identify potential problems with the blood, kidneys, or heart. Red cell distribution width (RDW) describes how different red blood cells are when it comes to their size. Ideally, all red blood cells will be similarly sized. A high RDW means that the body is creating red blood cells in very different sizes; this may be a sign of various health problems. Measuring the number of reticulocytes can diagnose certain types of anemia or provide information about the health of the bone marrow, kidneys, and liver. Platelets are small cell fragments that help form blood clots and prevent bleeding after an injury. Platelet numbers may drop as a result of health conditions like infection, autoimmune disease, or blood cancer, or may rise due to anemia, inflammatory health conditions, or other cancer types. Neutrophils are white blood cells that kill germs like bacteria, viruses, and fungi in order to protect the body from infection. Lymphocytes, including T cells and B cells, fight infection and produce antibodies (proteins that help the immune system find and destroy pathogens). Monocytes are white blood cells that protect the body from germs and remove dead or damaged cells. Eosinophils are a type of white blood cell that destroy parasites and cancer cells and are involved in the body’s allergic response. Basophils are white blood cells that recognize early signs of infection, help heal wounds, and help activate the body’s allergic response. Neutrophils are a type of white blood cell that kill germs like bacteria, viruses, and fungi in order to protect the body from infection. Eosinophils are a type of white blood cell that destroy parasites and cancer cells and are involved in the body’s allergic response. The Immature Granulocytes test describes what percentage of white blood cells are immature granulocytes. Certain types of white blood cells — neutrophils, eosinophils, and basophils — are granulocytes. Most of the granulocytes in the blood are fully-functioning and mature. Too many immature granulocytes may be a sign of infection, inflammation, or cancer. Nucleated red blood cells (NRBC) are immature (not yet fully functional) red blood cells. They are not usually found within the bloodstream, so their presence may indicate low oxygen levels, spleen conditions, or blood disorders such as leukemia.
  • Diagnostic Blood Test: Glucose Blood Urea Nitrogen (BUN) Creatinine eGFR BUN/Creatinine Ratio Sodium Potassium Chloride Carbon Dioxide, total Calcium Protein, total Albumin Globulin, total Albumin/Globulin (A/G) Ratio Alkaline Phosphatase (ALP) AST ALT Glucose is the sugar in the blood that the body metabolizes for energy. Hypoglycemia (low blood sugar levels) may be caused by certain medical conditions or by hormone imbalances and can lead to dizziness, shakiness, and anxiety. Hyperglycemia (high blood sugar levels) can be a sign of diabetes, stress, infections, or illness, and may lead to thirst, blurry vision, tiredness, and headaches. Aspartate aminotransferase (AST) is an enzyme created mainly by the liver and the heart. High levels can indicate damage to the liver caused by alcohol, drugs, or hepatitis. They can also signal heart conditions or pancreas problems. Alanine aminotransferase (ALT) is an enzyme mainly produced by the liver. It serves as a good indicator of liver damage caused by alcohol, drugs, or hepatitis. Checking levels of liver enzymes can help diagnose liver problems that are causing nausea, abdominal pain, fatigue, itchy skin, or loss of appetite. Albumin is a protein produced by the liver that helps keep fluid in the bloodstream and carries vitamins, hormones, and enzymes to the body’s tissues. Low albumin levels may be a sign of liver disease, kidney disease, thyroid conditions, infection, or inflammatory bowel disease, while high levels may indicate dehydration. Globulin proteins in the blood help the blood clot properly, fight off infections, and support liver and kidney health. Abnormal globulin levels can be a sign of liver disease, kidney disease, autoimmune disorders, infections, cancer, or inflammation. The blood urea nitrogen (BUN) test can help identify kidney issues. Urea nitrogen is a waste product that is typically filtered out by the kidneys. However, when the kidneys aren’t healthy, they may not remove all of this molecule, leading to higher levels in the blood. The Creatinine with eGFR test provides information about kidney health. As the muscles produce energy, they release creatinine, which is filtered out by healthy kidneys. If the kidneys aren’t functioning properly, creatinine may build up in the blood. Creatinine levels are used to calculate the estimated glomerular filtration rate (eGFR), which describes how well the kidneys are able to filter waste. Sodium is an electrolyte that helps control fluid levels and balance pH levels throughout the body. It’s also essential for the proper function of muscles and nerves. Atypical sodium levels may signal a variety of different health conditions, including kidney disease, diabetes, liver disease, thyroid conditions, or heart failure. Potassium is an electrolyte that helps carry nutrients into cells, remove waste from cells, maintain proper fluid levels in tissues, and help muscles and nerves work correctly. Changes in potassium levels may be a sign of kidney disease, diabetes, nutritional deficiencies, or other medical conditions. Chloride is a molecule that helps balance water levels in the body, maintain pH levels within different tissues, and control nerves and muscles. Abnormal levels of this electrolyte may be caused by problems with the kidneys, liver, heart, lungs, or adrenal glands. Carbon dioxide, total measures the total amount of CO2 in the body, including bicarbonate, an electrolyte form of CO2. CO2 is a waste product that is typically exhaled out of the body, so optimal CO2 levels are a sign that the lungs are healthy. Abnormal CO2 levels may also be a sign of hormone imbalances, kidney problems, or conditions that affect the adrenal glands. Calcium is a mineral important for many aspects of health and supports the function of the muscles, nerves, heart, and blood. Many different medical conditions can alter calcium levels, including bone disease, lung conditions, thyroid conditions, kidney disease, pancreatitis, or nutritional deficiencies. Protein, Total measures levels of globulins and albumin, the two most common blood proteins. Low levels of proteins in the blood may be a sign of liver or kidney conditions. Bilirubin is a protein that is created when red blood cells break down. It is normally filtered out by the liver. Elevated bilirubin levels may be a sign of various health conditions, such as liver damage, liver disease, or anemia. Alkaline phosphatase (ALP) is an enzyme located primarily in the liver and bones. High levels can indicate liver disease or bone growth, while low levels may signal a zinc deficiency.
  • Diagnostic Blood Test: Prolactin Prolactin is a hormone produced by the pituitary gland. Changes in prolactin levels may be a sign of problems with the pituitary, thyroid, kidneys, or hypothalamus. Excessive levels of prolactin can impair hormone production. In men, elevated levels can cause a reduced sex drive, erectile dysfunction, impaired fertility, and a lack of energy. In women, prolactin helps the breasts develop and triggers the production of milk. Atypical prolactin levels can lead to a reduced sex drive, impaired fertility, changes in menstrual periods, or the production of milk unrelated to childbirth. Note: This test may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin. Cease biotin supplementation at least 72 hours prior to blood draw.
  • Diagnostic Blood Test: Sex Hormone-Binding Globulin (SHBG) Sex Hormone-Binding Globulin (SHBG) is a protein made in the liver that binds to sex hormones, helping to stabilize and transport them to the body’s tissues. Abnormal SHBG levels can lead to hormonal imbalances, metabolic dysfunction, and decreased sexual function. Low SHBG may also be a sign of thyroid conditions, diabetes, polycystic ovary syndrome (PCOS), or cancer, while high levels can signal problems with the liver, thyroid, pituitary gland, or testicles. Note: This test may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin. Cease biotin supplementation at least 72 hours prior to blood draw.
  • Diagnostic Blood Test: Vitamin D Vitamin D is both a vitamin and a steroid hormone. Within the body, vitamin D is converted into 25-hydroxy vitamin D. This nutrient is essential for bone strength, mineral absorption, and immune function. Having adequate vitamin D levels may also protect against conditions like heart disease and diabetes.
  • Diagnostic Blood Test: C-Reactive Protein, High Sensitivity (hs-CRP) The liver releases C-reactive protein (CRP) in response to inflammation. Elevated CRP levels may be a sign of unresolved inflammatory cascades and immune dysfunction. Chronically elevated CRP is associated with increased risk of heart disease. The high-sensitivity CRP (hs-CRP) test more accurately measures low levels of the CRP protein compared to standard tests.
  • Diagnostic Blood Test: Prostate Specific Antigen (PSA) Prostate-Specific Antigen (PSA) is a protein produced by the prostate. Elevations of PSA are a marker of prostate cancer or another prostate problem such as prostatitis or benign prostatic hyperplasia (BPH). High PSA levels may indicate the need for re-testing, a prostate exam, or potentially a biopsy.
  • Diagnostic Blood Test: HBa1c (Hemoglobin A1c) The hemoglobin A1C or HbA1c test helps diagnose diabetes and prediabetes. It measures average levels of blood sugar over the past three months and is a valuable marker of insulin sensitivity. HbA1c testing may be especially important for people with certain diabetes risk factors such as high blood pressure, obesity, or low levels of physical activity.
  • Diagnostic Blood Test: Luteinizing Hormone (LH) Follicle-stimulating hormone (FSH) Luteinizing Hormone (LH) is a pituitary gonadotropin that stimulates the gonads to produce sex hormones. LH also plays important roles in fertility. Follicle-Stimulating Hormone (FSH) is a pituitary gonadotropin that stimulates the gonads and plays important roles in fertility. Note: This test may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin. Cease biotin supplementation at least 72 hours prior to blood draw.
  • Insulin

    $11.00
    Diagnostic Blood Test: Insulin Insulin is a hormone that controls levels of sugar in the blood and encourages cells to absorb this sugar to use as fuel. Elevated levels of insulin may be a sign of insulin resistance — a precursor to type 2 diabetes. Important: Patient should be fasting at time of collection. Note: This test may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin. Cease biotin supplementation at least 72 hours prior to blood draw.
  • Cortisol

    $10.00
    Diagnostic Blood Test: Cortisol Cortisol is the “stress hormone” that helps your body respond to short- or long-term stress and trauma. Cortisol plays important roles in immune function and plays a role in controlling metabolism. Abnormal cortisol levels may be a sign of a tumor or of adrenal gland problems such as Cushing’s syndrome or Addison's disease. Prolonged elevation of cortisol can cause fatigue, immune dysfunction, and negatively impact sex hormones.
  • Diagnostic Blood Test: Estradiol, Sensitive (LC/MS-MS) Estradiol or E2 is the principle estrogen in men and women. Estradiol plays important roles in neuroprotection, fertility, metabolism, and anabolism. Imbalanced levels of Estradiol may be associated with erectile dysfunction, low libido, gynecomastia (the growth of breast tissue), hair loss, reduced muscle strength, or low energy levels. The Estradiol, Sensitive test can more accurately measure levels of estradiol in men and post-menopausal women, who typically have lower levels of this hormone.
  • Diagnostic Blood Test: Thyroid Stimulating Hormone (TSH) Thyroxine (T4) T3 Uptake Free Thyroxine Index For a more comprehensive analysis of thyroid health we recommend the Comprehensive Thyroid Panel, available here: https://marekhealth.com/product/comprehensive-thyroid-panel/ Note: This test may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin. Cease biotin supplementation at least 72 hours prior to blood draw.
  • Diagnostic Blood Test: Ferritin Ferritin is a protein in the blood that helps store iron, which is important in forming hemoglobin (the protein that transports oxygen to the body’s tissues). Having high ferritin levels may be a sign of having too much iron stored in the body, which may point to liver disease, haemochromatosis, or thyroid dysfunction. Ferritin is also an acute-phase reactant and may be elevated due to inflammation. Low ferritin may indicate anemia or bleeding problems.
  • Diagnostic Blood Test: Iron Iron (Transferrin) Saturation % Total Iron-binding Capacity (TIBC) Unsaturated Iron-binding Capacity (UIBC) Iron: Iron is an important component of hemoglobin, the protein in red blood cells that carries oxygen from the lungs to the rest of the body. Without enough iron, the body can’t make hemoglobin, leading to anemia. However, excessive levels of iron can become toxic to cells and damage organs. Iron Saturation: Within the bloodstream, iron is attached to transferrin, a protein that helps carry iron to organs and tissues. This test measures the amount of iron bound to transferrin. It can indicate whether iron stores in the body are sufficient and whether adequate iron is being transported around the body. TIBC: Total iron-binding capacity (TIBC) measures the amount of transferrin available to bind with iron. An abnormal TIBC may point to health conditions like anemia, inflammation, nutrition deficiencies, or liver disease. UIBC: Unsaturated iron-binding capacity (UIBC) measures how much transferrin remains unattached to iron. Iron-related tests can help identify anemia, which causes tiredness, headaches, and dizziness, or iron overload, leading to joint pain, low energy levels, and abdominal pain. For a more comprehensive look at your iron status we recommended also testing Ferritin, available here: https://marekhealth.com/product/ferritin/
  • Diagnostic Blood Test: Urinalysis, Routine Specific Gravity pH Urine-Color Appearance WBC Esterase Protein Glucose Ketones Occult Blood Bilirubin Urobilinogen,Semi-Qn Nitrite, Urine w/ Reflex to Microscopic Examination The kidneys, which produce urine, are important for filtering out toxins and waste, maintaining proper hormone levels, and balancing levels of fluids and minerals in the body. Testing the urine through urinalysis can detect kidney problems, identify other health conditions such as diabetes, UTI, and provide information about overall health.
  • Diagnostic Blood Test: Progesterone Progesterone is a hormone that has powerful effects on sexual health, sleep quality and libido. Progesterone is a precursor of testosterone and helps balance estrogen. In men, low progesterone levels may cause a low sex drive, erectile dysfunction, hair loss, tiredness, weight gain, loss of bone and muscle, or depression. In women, low progesterone levels may cause irregular periods, abnormal bleeding, miscarriage, low sex drive, weight gain, or gallbladder problems. Rises in progesterone levels during the mid-luteal phase is an indicator of healthy ovulation. Note: This test may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin. Cease biotin supplementation at least 72 hours prior to blood draw.
  • Diagnostic Blood Test: Thyroid-Stimulating Hormone (TSH) Thyroid-Stimulating Hormone (TSH) is an important marker for thyroid health which governs energy and metabolism. TSH acts as a signal that tells the thyroid when to produce more thyroid hormone. Abnormal thyroid levels may result in weight changes, heart rate changes, sleeping problems, hair loss, anxiety, or fatigue. Note: This test may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin. Cease biotin supplementation at least 72 hours prior to blood draw.
  • Diagnostic Blood Test: Magnesium Magnesium is a mineral and electrolyte essential for many important body processes, including controlling blood pressure, maintaining healthy blood sugar levels, and supporting healthy function of the nerves, muscles, bones, and heart. Abnormal magnesium levels may help explain symptoms like low energy levels, muscle cramps, heart palpitations, and breathing problems.
  • Diagnostic Blood Test: Insulin-like Growth Factor 1 (IGF-1) Insulin-like growth factor 1 (IGF-1) is our best biomarker for human growth hormone (HGH) status. HGH is a hormone that encourages growth, cell division, and tissue regeneration. It also plays an important role in body composition and bone strength. IGF-1, produced by HGH in the liver, stimulates muscle growth, the production of new proteins, and the breakdown of fat molecules. Note: This test may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin. Cease biotin supplementation at least 72 hours prior to blood draw.
