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.
