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 the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) across 24 clinical and laboratory items to quantify lupus disease activity and guide treatment decisions

Each component has a specific meaning:

  • 24 clinical — The 24 clinical recorded for the scenario being assessed.
  • Laboratory items — The laboratory items recorded for the scenario being assessed.

Note: Interpret the sledai-2k score result against the thresholds and context described above.

How to Use

Enter the 24 clinical, laboratory items for the scenario you are assessing. Calculate the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) across 24 clinical and laboratory items to quantify lupus disease activity and guide treatment decisions. Use the sledai-2k score result to inform your calculation.
