A doctor needs to assess this symptom in person. A blood test alone can't rule out a serious cause.
That's why we do not include this symptom in your test advice. You can still finish the test finder for your other symptoms.

—Targeted testing beats testing everything: values without a clear reason mostly add noise, not insight.
Still want a baseline?
No indication — but if you're curious where you stand, the general check-up covers the values a GP looks at in a preventive check.

Frequently asked questions
Is this medical advice?
No. The test finder translates your answers into test advice using the same logic GPs use when ordering blood tests, but it does not diagnose. If you have symptoms, see your GP.
Why do you sometimes advise NOT to test?
Targeted testing beats testing everything. We follow the principle of problem-oriented ordering: only values with a clear reason. That is also why we tell you what you can skip.
What happens to my answers?
Without an account, we do not save your answers. With an account, you can save your advice and revisit it later.
