Chapter 01 · The why
Why a panel beats a single test
Hormones work as a system, so one value out of context rarely tells the whole story. A panel looks at several related markers together: the sex hormones (estradiol, progesterone, testosterone), the pituitary signals that drive them (LH and FSH), the binding protein that affects how much is active (SHBG), and common look-alikes such as thyroid (TSH) and prolactin that can cause similar symptoms.1 The right panel depends on who you are and what is bothering you.

Timing and preparation matter too. Some markers shift across the menstrual cycle, and testosterone is usually drawn in the morning, so a clinician decides not just what to test but when. This guide suggests what to raise in that conversation; it does not order anything or interpret a result for you.
Chapter 02 · The fine print
What this guide does not do
This is educational. It does not diagnose a hormone problem, order labs, or tell you that you need treatment. Symptoms such as low energy, low libido, or mood changes have many causes, and a normal panel does not rule everything out while an abnormal value is not a diagnosis on its own. A licensed physician decides which tests are appropriate, interprets them alongside your history, and recommends next steps. Individual results vary.
A single result is a snapshot
How often should we draw?
One panel, repeated. More draws means you see change instead of a single snapshot. Tap an answer to start your Lab Pass.
Bring this list to a visit as a starting point. A clinician tailors the actual panel to your history, your symptoms, and the timing that makes the results meaningful. Individual results vary.
