Why LC/MS-MS Matters
Standard tests vs. LC/MS-MS: Most labs use “Immunoassays,” which are great for average men but often inaccurate at the very low levels found in women or men with severe Low-T. LC/MS-MS (Liquid Chromatography-Mass Spectrometry) is significantly more sensitive, ensuring your results aren’t just a “guess” at the low end of the scale.
Use:
This profile is designed to test for low testosterone. It uses the latest technology to determine whether those symptoms or feelings are related to a decline in the sex hormone, testosterone.
Who Should Take This Test?
This test is specifically designed for individuals where standard testosterone testing may fall short. It is highly recommended for:
-
Women: To evaluate PCOS (Polycystic Ovary Syndrome), hirsutism (excess hair growth), or low libido.
-
Men: To confirm a diagnosis of hypogonadism (Low-T) when levels are expected to be very low.
-
Children: To evaluate early or delayed puberty.
The Importance of Timing
For the most accurate results, it is recommended that you visit the lab in the early morning (between 7:00 AM and 10:00 AM). Testosterone levels naturally fluctuate throughout the day and are at their peak during these hours.
Women and Males who have hypogonadism, a condition in which the body does not produce enough of the testosterone hormone.
