Why does this panel test for free testosterone and not total?

The reason we choose to provide free testosterone as a marker in our test is that it is possible to have a normal total testosterone level in blood but an abnormal free testosterone level in saliva. When that happens, many health care providers choose to look at what a person's symptoms may be to determine if the free testosterone or total testosterone level is more likely to be representative of what is really happening in the body.

Free Testosterone unit of measure:

Each lab is able to determine the unit of measure and biomarker used. You can convert pg/mL to ng/dL as we know many internet resources discuss free testosterone levels as ng/dL. The conversion factor is simply a division of your result by 10 (if your result was 100 pg/mL then that becomes 10 ng/dL).
