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

Estimate duration of B-cell depletion after rituximab therapy and timing for revaccination, pregnancy planning, and infection risk assessment based on dose and number of cycles

Each component has a specific meaning:

  • Dose — The dose recorded for the scenario being assessed.
  • Number of cycles — The number of cycles recorded for the scenario being assessed.

Note: Interpret the rituximab b-cell duration result against the thresholds and context described above.

How to Use

Enter the dose, number of cycles for the scenario you are assessing. Estimate duration of B-cell depletion after rituximab therapy and timing for revaccination, pregnancy planning, and infection risk assessment based on dose and number of cycles. Use the rituximab b-cell duration result to inform your calculation.
