How to Read Your Own Blood Test Results (Without Panicking)

One red number at 11 p.m. cansend an otherwise healthy person into a full worst-case spiral before their doctor has even seen the result. In this Season 2 episode, Dr Cois walks through the framework physicians actually use to read a lab report: why a “normal range” isn’t the line between healthy and sick, why 1 in 20 healthy people flag on any given test, why how far out of range a value is matters more than the color of the flag, and the one question that defuses almost any result. This is the home base for the whole Lab Results Explained series, and the episode that makes all the test-specific ones make sense. Companion guide and references at DrCois.com.
