Fibromyalgia diagnostic test (ACR/EULAR 2010/2016)
An interactive version of the FMS diagnostic questionnaire based on the American College of Rheumatology (ACR) and EULAR criteria from 2010/2016. The result is calculated automatically at the end of the test.
A positive result is not a diagnosis — a full diagnosis requires excluding other conditions (lupus, Lyme disease, RA) by a rheumatologist or neurologist.
Before you start
- Fill in the test if your pain has lasted longer than 3 months.
- Focus only on symptoms from the current week.
- Take current medication and therapy effects into account — if drugs mask the pain, imagine how you would feel without them.
- Take other diagnosed coexisting conditions into account (e.g. do not mark facial pain if you have diagnosed trigeminal neuralgia).
Part 1 — Widespread Pain Index (WPI)
Check every body region where you felt pain in the last week.
Regions checked (WPI): 0 / 20
Part 2 — Symptom Severity Scale (SS-a)
Rate the severity of each of the three symptoms over the last week.
Sum SS-a: 0 / 9
Part 3 — Symptom Severity Scale (SS-b)
Check every additional symptom you experienced in the last week.
Symptoms checked: 0 · SS-b index: 0
Your result
- WPI (pain spread)
- 0
- SS-a (main symptoms)
- 0
- SS-b (other symptoms)
- 0 (0)
- SS (sum of SS-a + SS-b)
- 0
Diagnostic threshold — when do we call it fibromyalgia
Fibromyalgia is diagnosed when the following thresholds (ACR/EULAR 2010/2016) are met:
- WPI ≥ 7 and SS ≥ 5, or
- WPI 3–6 and SS ≥ 9.
A positive result may also indicate other conditions with similar symptoms, such as systemic lupus, Lyme disease or rheumatoid arthritis. Final diagnosis is made by a physician after ruling out other causes.
