Autoinflammatory Periodic Fever Syndrome Classifier

Classifies autoinflammatory periodic fever syndromes (FMF, TRAPS, CAPS, MKD, PFAPA) using fever episode characteristics, duration, associated features, serum amyloid A, and genetic testing results.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Classifies autoinflammatory periodic fever syndromes (FMF, TRAPS, CAPS, MKD, PFAPA) using fever episode characteristics, duration, associated features, serum amyloid A, and genetic testing results

Each component has a specific meaning:

  • Fever episode characteristics — The fever episode characteristics recorded for the scenario being assessed.
  • Duration — The duration recorded for the scenario being assessed.
  • Associated features — The associated features recorded for the scenario being assessed.
  • Serum amyloid A — The serum amyloid a recorded for the scenario being assessed.
  • Genetic testing results — The genetic testing results recorded for the scenario being assessed.

Note: Interpret the periodic fever classifier result against the thresholds and context described above.

How to Use

Enter the fever episode characteristics, duration, associated features, serum amyloid A, genetic testing results for the scenario you are assessing. Classifies autoinflammatory periodic fever syndromes (FMF, TRAPS, CAPS, MKD, PFAPA) using fever episode characteristics, duration, associated features, serum amyloid A, and genetic testing results. Use the periodic fever classifier result to inform your calculation.
