About LabInformation

LabInformation.org publishes independent, plain-language guides to laboratory testing. Our goal is simple: help you understand what a test measures and what it involves before you spend money on it.

How we work

Every test page explains the purpose of the test, the sample type, typical preparation, and how results are reported. We do not diagnose, treat, or interpret results for you; that belongs with a licensed healthcare professional.

How we make money

Some links on this site are affiliate links. If you order a test through one, we may earn a commission at no extra cost to you. This never changes what we publish or how we describe a test.

Editorial standards

• Content is written for a general audience and reviewed for clarity.
• We cite authoritative sources for medical definitions where possible.
• We never invent reviews, testimonials, or credentials.
