What it measures.

In plain English. This describes what a lab measures; it cannot tell you what your own result means.

  • Total testosteroneTotal T

    All the testosterone in the blood, both the part carried by proteins and the small part that circulates free. It is highest in the morning, which is why it is usually drawn early.

How to prepare.

  1. No fasting needed. Eat and drink as usual.
  2. No testosterone cream or gel on the inner arms for 24 hours before the draw.

Often taken with it.
