Glasgow-Blatchford Bleeding Score
Admission blood urea concentration, the source-native laboratory predictor. This calculation accepts blood urea, not BUN, to preserve the published mmol/L table.
Admission haemoglobin concentration. Scoring thresholds depend on the source table's sex category.
The published haemoglobin table uses the categories men and women; it does not define a scoring rule for other categories.
Initial systolic blood pressure at presentation.
Pulse/heart rate at presentation.

Method
Points are assigned for urea, sex-specific haemoglobin, systolic blood pressure, pulse, melaena, syncope, hepatic disease, and cardiac failure. The result is the integer sum of the eight components, from 0 to 23 points.
