Testosterone controls the development of typical male features (e.g., deep voice, face and body hair, muscle bulk) and male fertility. Abnormally low levels of testosterone can decrease sexual performance, muscle and bone strength, and increase fatigue and depression. It is the Free Active testosterone tested and not the Total testosterone measured by this test.
DHEA-S Dehydroepiandrosterone sulphate is the major precursor of sex hormones in males and females. Low DHEA-S levels will lead to reduced levels of other sex hormones and also can cause depression, loss of bone and muscle strength, and low sexual function.
Measurement unit used – pmol/L. This means that very low levels of hormones can be detected with an accurate read-out of hormone concentration. Measurement Unit Conversion calculators can be used to compare any old records you may have in different measurement units.

More: There is no ideal specimen type for measuring hormones since there are advantages to each, depending on clinical goals. In the case of stress hormones, the majority of circulating hormones are bound to proteins and are biologically inert. Salivary testing assesses unbound, biologically-active level of the hormone within your body.
