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

Calculate fexofenadine bioavailability change from ABCB1/P-gp polymorphisms and grapefruit juice inhibition

Each component has a specific meaning:

  • ABCB1/P-gp polymorphisms — The abcb1/p-gp polymorphisms recorded for the scenario being assessed.
  • Grapefruit juice inhibition — The grapefruit juice inhibition recorded for the scenario being assessed.

Note: Interpret the fexofenadine abcb1 result against the thresholds and context described above.

How to Use

Enter the ABCB1/P-gp polymorphisms, grapefruit juice inhibition for the scenario you are assessing. Calculate fexofenadine bioavailability change from ABCB1/P-gp polymorphisms and grapefruit juice inhibition. Use the fexofenadine abcb1 result to inform your calculation.
