Hormones
Testosterone, total
Core panel — run every month
What it indicates
All testosterone in the blood, both the portion bound to proteins and the portion that is free.
Why a series helps
Testosterone varies through the day and between days, so one morning reading is a snapshot of a moving value.
What this page does not tell you
What a particular Testosterone, total result means depends on you: your history, your medication, why the test was taken. Ziro does not interpret results for individuals and does not diagnose. If something in your results warrants a conversation, that conversation is with a doctor, and your results are downloadable so you can bring them.
