Lab Literacy Guide by a Clinical Laboratory Scientist

What Is Lab Literacy?

Lab literacy is the ability to understand, interpret, and act on your own laboratory results. Most patients receive their lab results with little explanation — a list of numbers, a “normal” or “abnormal” flag, and a follow-up appointment weeks away. Lab literacy closes that gap.

Why It Matters

Your lab results contain some of the most objective, actionable health data available to you. Understanding them empowers you to have better conversations with your provider, catch trends early, and make informed decisions about nutrition, supplementation, and lifestyle.
