Video Capsule Endoscopy Bleeding Probability Calculator

Estimate probability of positive video capsule endoscopy (VCE) finding in obscure GI bleeding based on hemoglobin drop, transfusion requirement, and time since last bleed. Overt active bleed: 70-90% yield.

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 probability of positive video capsule endoscopy (VCE) finding in obscure GI bleeding based on hemoglobin drop, transfusion requirement, and time since last bleed. Overt active bleed: 70-90% yield

Each component has a specific meaning:

  • Hemoglobin drop — The hemoglobin drop recorded for the scenario being assessed.
  • Transfusion requirement — The transfusion requirement recorded for the scenario being assessed.
  • Time since last bleed — The time since last bleed recorded for the scenario being assessed.

Note: Interpret the capsule bleeding probability result against the thresholds and context described above.

How to Use

Enter the hemoglobin drop, transfusion requirement, time since last bleed for the scenario you are assessing. Estimate probability of positive video capsule endoscopy (VCE) finding in obscure GI bleeding based on hemoglobin drop, transfusion requirement, and time since last bleed. Overt active bleed: 70-90% yield. Use the capsule bleeding probability result to inform your calculation.
