Frequently asked

Questions & answers

Are the questionnaires medically validated?

Yes. All checks are based on peer-reviewed criteria: the ME/CFS checks on the Canadian Consensus Criteria, the FunCaP-27 on a validated functional-capacity questionnaire, the fibromyalgia check on the ACR-2016 criteria.

What happens to my answers?

Your data are used solely to compute your result. We do not store personally identifiable data without your explicit consent. All processing is GDPR compliant.

Can I take the result to my doctor?

Yes. You can export your result as a PDF and share it with your physician. It makes preparing for complex symptom conversations much easier.

How long do the checks take?

The ME/CFS symptom check takes 5–10 minutes, the fibromyalgia check about 5 minutes. The FunCaP-27 severity assessment is longer, taking 15–20 minutes.

What does a noticeable result mean?

A noticeable result shows that your symptom pattern matches features of the examined condition. It does not replace a diagnosis – please seek medical advice and use it as a conversation starter.

Questions that help with choosing the right questionnaire

Pick the assessment that matches your current question – ME/CFS suspicion, severity grading, or fibromyalgia-leaning symptom patterns.

Which questionnaire should I take if I suspect ME/CFS?

If the question is diagnostic orientation, the criteria-based assessment is usually the right start. If severity and daily limitation matter, a functional assessment can add more detail.

Open the ME/CFS symptom check

Which questionnaire helps when widespread pain is the main problem?

If pain distribution, fatigue, unrefreshing sleep, and cognitive symptoms are the main pattern, the fibromyalgia symptom check is the most direct starting point.

Open the fibromyalgia check

What is the difference between an ME/CFS symptom check and FUNCAP-27?

The ME/CFS symptom check helps with criteria-oriented symptom orientation. FUNCAP-27 is more useful when the question is severity, functional capacity, daily limits, or change over time.

Open FUNCAP-27

Does a questionnaire diagnose ME/CFS or fibromyalgia?

No questionnaire replaces medical diagnosis. It can structure symptoms, estimate burden, and make follow-up discussions more precise.

Open questionnaire overview

What do WPI and Symptom Severity Score mean in a fibromyalgia check?

WPI counts painful body regions. Symptom severity adds burden from fatigue, unrefreshing sleep, cognitive symptoms, and related complaints.

Open WPI symptom check

Why is PEM relevant before or after a questionnaire result?

PEM changes how symptoms, exertion, and recovery should be interpreted. Without that layer, a questionnaire result can stay too abstract.
