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

Determine severe cutaneous adverse reaction risk from allopurinol based on HLA-B*5801 status and renal function

Each component has a specific meaning:

  • Allopurinol based on HLA-B*5801 status — The allopurinol based on hla-b*5801 status recorded for the scenario being assessed.
  • Renal function — The renal function recorded for the scenario being assessed.

Note: Interpret the allopurinol hla-b*5801 result against the thresholds and context described above.

How to Use

Enter the allopurinol based on HLA-B*5801 status, renal function for the scenario you are assessing. Determine severe cutaneous adverse reaction risk from allopurinol based on HLA-B*5801 status and renal function. Use the allopurinol hla-b*5801 result to inform your calculation.
