Common Hormone Panel - Bioref

This panel measures the core sex hormones and the pituitary signals that regulate them, so you can see not just hormone levels but how the whole axis is working together. Testosterone (total and free) and estradiol tell you about circulating hormone activity, while SHBG explains how much of that testosterone is actually bioavailable versus bound and inactive — a low or high SHBG can dramatically change what a total testosterone number means. FSH and LH reflect the pituitary's signaling to the gonads, which helps distinguish whether a low sex-hormone level originates in the testes/ovaries or in the brain's control center — a distinction a single hormone test cannot make. Because these markers are interpreted in context of one another, this combination answers practical questions about libido, energy, menstrual regularity, fertility, and recovery that isolated tests leave ambiguous. The estradiol and testosterone here use LC/MS methodology, which offers greater accuracy at the low concentrations relevant to women and to men monitoring subtle changes. Ordering these five markers together in one draw is more efficient and less costly than piecing them together individually, and it gives you a coherent snapshot rather than disconnected data points.
