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

Calculates the Niemann-Pick disease type C Suspicion Index (NPC-SI) to identify patients who should undergo diagnostic testing, based on neurological, psychiatric, and visceral findings with age-weighted scoring

Each component has a specific meaning:

  • Neurological — The neurological recorded for the scenario being assessed.
  • Psychiatric — The psychiatric recorded for the scenario being assessed.
  • Visceral findings — The visceral findings recorded for the scenario being assessed.

Note: Interpret the npc suspicion score result against the thresholds and context described above.

How to Use

Enter the neurological, psychiatric, visceral findings for the scenario you are assessing. Calculates the Niemann-Pick disease type C Suspicion Index (NPC-SI) to identify patients who should undergo diagnostic testing, based on neurological, psychiatric, and visceral findings with age-weighted scoring.
