Clear responsible health testing

What these tests can and cannot show.

Add-on tests provide additional information, but they do not diagnose a medical condition or replace appropriate medical care. Results are considered alongside your symptoms, health history, medication, lifestyle and other relevant findings.

An abnormal result does not necessarily confirm the cause of a symptom, and a result within range does not rule out every possible cause. Testing should never delay assessment by your GP or another appropriately qualified healthcare professional.
