Every acronym on your lab report, in plain English.

A lab report shouldn’t be an IQ test. Most panels come back with a dense grid of acronyms - ApoB, HbA1c, SHBG, hs-CRP, fasting insulin, LH, FSH, ferritin - and a flag system that tells you whether a value is “normal” relative to a reference range that was never calibrated to your age, sex, or goals. The job of this glossary is to translate those terms directly, without the pop-science hand-waving and without burying you in caveats.

Each entry is short on purpose. The definition up top is the one a good primary care physician would give you in a two-minute conversation. Below that we link to the labs that measure the marker, the care paths it connects to, and deeper learn articles when a fuller explanation earns the click. If a term has a regulatory status (Rx, DSHEA supplement, research compound), we mark that too.

If you want opinionated calls between two options, see /compare. If you want to start with your own labs, the assessment routes you to the right panel and the right care path.
