Glasgow–Blatchford score
Pre-endoscopic score estimating transfusion, therapeutic endoscopy or surgery need in upper GI bleeding from urea, hemoglobin, vital signs and comorbidities.

GBS/Blatchford 2000: 8 variables, total 0–23, urea not BUN
The 2000 Glasgow-Blatchford was developed at the initial presentation of upper gastrointestinal bleeding to stratify treatment need. The score alone does not authorize discharge or outpatient management. Urea and hemoglobin units, comorbidity definitions and cutoffs in later protocols must match the version used. Table 2(d) of the primary Dakik 2017 study reproduces urea ≥ 10 to ≤ 25 mmol/L as 4 points and > 25 mmol/L as 6 points; the local label uses ≥ 25 mmol/L for 6 points. The original Blatchford 2000 table was not obtained in this review. The sum of selected categories was checked, but the exact 25 mmol/L boundary and rounded mg/dL ranges remain unadjudicated.
Conditions of use
Check the population, units, inclusion and exclusion criteria, and version in the original source. A result alone does not establish a diagnosis, discharge decision or prescription.
