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

Stratify pleural effusion management using BTS guidelines based on size, biochemistry, cytology, and clinical features

Each component has a specific meaning:

  • BTS guidelines based on size — The bts guidelines based on size recorded for the scenario being assessed.
  • Biochemistry — The biochemistry recorded for the scenario being assessed.
  • Cytology — The cytology recorded for the scenario being assessed.
  • Clinical features — The clinical features recorded for the scenario being assessed.

Note: Interpret the bts pleural result against the thresholds and context described above.

How to Use

Enter the BTS guidelines based on size, biochemistry, cytology, clinical features for the scenario you are assessing. Stratify pleural effusion management using BTS guidelines based on size, biochemistry, cytology, and clinical features. Use the bts pleural result to inform your calculation.
