Medical disclaimer

Information only – not medical advice

Everything on LongevityBloodTest.com, including biomarker explainers, guides, comparison tables and reviews, is general information for education. It is not medical advice and isn't a substitute for advice from a doctor or other qualified health professional who knows your situation.

Blood tests don't diagnose on their own

The tests we compare give you measurements from one moment in time. A result inside or outside a lab's reference range is not a diagnosis, and a normal result doesn't rule out a condition. We don't claim that any test detects, prevents or diagnoses any disease.

Talk to a doctor about your results

• Share your full report – including the reference ranges – with your doctor, especially if a result is flagged.
• Don't start, stop or change any medicine, supplement or treatment based on a test result or on anything you read here without medical advice.
• If you have symptoms, or a family history that worries you, see a doctor rather than relying on a private test.

Who this site is for

Our content is written for healthy adults who want to test proactively. If you're managing a diagnosed condition, are pregnant, or are under 18, speak to your doctor about the right tests for you.

In an emergency

If you think you may have a medical emergency, call your local emergency number immediately (for example 112 in the EU, 999 in the UK or 911 in the US).

Accuracy

We work to keep information accurate and up to date, and base our health content on published clinical guidelines; it is not yet reviewed by a medically qualified reviewer. Medical knowledge, guidelines and provider details change, so we can't guarantee that every page is complete or current at the time you read it. See each page's "last updated" date.

Third-party providers

Tests are sold and carried out by independent providers. They are responsible for their tests, labs, results, clinical advice and customer service. Please read their terms before ordering.
