About RequestALab

RequestALab is an independent, editorially driven directory of laboratory tests. Our goal is simple: make it easy to understand what a test measures before you decide to order one.

What we do

We publish plain-language descriptions of hundreds of laboratory tests and organize them by state and community, so you can read about a test, understand what the sample involves, and request a confidential collection near you.

What we do not do

We are not a healthcare provider, a laboratory, or a medical practice. We do not diagnose conditions, interpret your results, or give individual medical advice. Decisions about testing and treatment belong with you and a licensed clinician.

How we are funded

RequestALab is supported by affiliate partnerships. When you order a test through a link on this site, we may earn a commission at no additional cost to you. This never changes what you pay, and it does not influence the educational content we publish.

Editorial approach

Test descriptions are written for a general audience and reviewed for accuracy and clarity. We avoid promising specific prices, wait times, or availability, because those details vary by collection site and change over time.
