Blood test markers, explained

Reference ranges for the 88 markers HealthOS reads off a lab report — what each one measures, what moves it, and what actually brings it back into range. Ranges adjust for sex and age, because a healthy ferritin at 30 is not a healthy ferritin at 60.

Reference ranges are general-population guidance compiled from common clinical laboratories, not a diagnosis. Lab-to-lab ranges differ. Always read your results with your doctor.
