- Results report
Male Testosterone Monitoring (RDX_213) tracks total testosterone, free androgen index, and estradiol from a venous blood draw, helping men assess response after 3‑6 months of testosterone therapy.
About this treatment
Male Testosterone Monitoring (RDX_213) focuses on three key hormones—Total Testosterone, Free Androgen Index (FAI), and Estradiol (E2)—measured from a venous blood sample. This panel may support clinicians in evaluating how a patient is responding after 3‑6 months of testosterone therapy, ensuring appropriate dosing and monitoring for hormonal balance. Results are returned within the clinic’s standard turnaround period. The package includes the blood draw, laboratory analysis of the three hormones, and a concise results report. No fasting is required. Tailored for men already on testosterone replacement, it provides a focused follow‑up metric to guide ongoing treatment decisions.

Biomarkers tested
3The most potent and prevalent form of estrogen. In women, estradiol regulates the menstrual cycle, fertility, and bone density. In men, it's produced from testosterone and plays roles in bone health and libido. Levels vary significantly with age and menstrual cycle.
A calculated ratio of total testosterone to SHBG that estimates the amount of biologically active testosterone. FAI is particularly useful in women for assessing androgen excess in conditions like PCOS.
The primary male sex hormone, also important in women at lower levels. Testosterone regulates muscle mass, bone density, fat distribution, libido, and mood. Levels decline naturally with age in both sexes.
