View the instructions for collecting and submitting your hair sample for the Testosterone Test.
A hair testosterone test looks at testosterone measured in a hair sample, which can provide information about hormone exposure over a longer period of time. Blood testing measures testosterone circulating in the blood at a specific point in time, so the two methods are not directly interchangeable.
Follow the Collection Instructions provided after purchase for the approved collection area, required hair length, and amount of hair needed. Submitting the correct sample helps ensure there is enough material for laboratory analysis.
Once your sample has been received and laboratory analysis is complete, your report will be delivered electronically. The report provides information about the testosterone measured in your submitted hair sample and is intended for informational and wellness purposes, not to diagnose a hormone disorder or medical condition.
