Medical Disclaimer

Please read this before using anything you learn on this site. It is short, and it matters.

Educational information, not medical advice

Everything on BloodTestEasy is general educational information. It explains what blood tests measure and what typical ranges look like for adults. It is not medical advice, diagnosis, or treatment, and it cannot be — because we do not know you, your history, your symptoms, your medications, or your other results. Only a clinician who does can interpret your numbers.

Never delay seeking medical care, ignore your doctor's advice, or start or stop a medication because of something you read here.

No doctor-patient relationship

Reading this site, or emailing us, does not create a doctor-patient relationship of any kind. We do not provide consultations or interpret individual results.

Emergencies

If you think you may be having a medical emergency, do not use this website — call your local emergency number right away (911 in the United States, 999 in the United Kingdom, 995 in Singapore) or go to the nearest emergency department.

Adults only

All reference ranges and explanations on this site apply to adults. Normal values for children and teenagers are often different, sometimes very different. Please do not use this site to interpret a child's results — talk to their pediatrician instead.

Lab ranges vary

Different laboratories use different equipment and methods, so their reference ranges differ too. The range printed on your lab report is the one that applies to your result. If a typical range shown on this site differs from the one on your report, go with your report — and with your doctor's reading of it.

One value is not the whole story

A single result slightly outside the typical range is common and often harmless. Doctors interpret results in context: trends over time, other values, symptoms, and your overall health. A value on its own — high, low, or normal — is never a diagnosis and never a guarantee that all is well.

Accuracy

We base our content on guidance from established medical organizations and link our sources on every page, and we work to keep pages current. Even so, medical knowledge changes and errors are possible, so we cannot guarantee that every page is complete or up to date at the moment you read it. If you spot a problem, please tell us.

By using this site, you agree that decisions about your health belong with you and your own healthcare providers — which is exactly where they should be.
