About LabPreparation
How the guides are researched, what sources they draw on, and the limits of what an educational site can tell you.
- Independent
- Evergreen
- Not medical advice
LabPreparation is an independent, editorially driven directory of laboratory tests. Our goal is simple: make it easy to understand how to prepare for a test before you decide to order one.
What we do
We publish plain-language preparation guides for hundreds of laboratory tests and organize them by state and community. Each page explains whether fasting applies, the best time to collect, the sample type, what to bring, and what the test measures.
What we do not do
We are not a healthcare provider, a laboratory, or a medical practice. We do not diagnose conditions, interpret results, or give individual medical advice. Decisions about testing and treatment belong with you and a licensed clinician.
How we are funded
LabPreparation 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.
