What does QBL stand for in obstetric practice?

• A. Quantitative Blood Loss
• B. Quick Blood Loss
• C. Quality of Blood Loss
• D. Quasi Blood Loss

Answer: (A)

The concept being tested is using a Quantitative Blood Loss approach to measure blood loss during obstetric care. Quantitative Blood Loss means actually quantifying how much blood is lost, not just guessing by sight. In practice, this involves weighing all blood-soaked materials (pads, gauze, clothing) and measuring any suction canister contents, then subtracting the dry weights and converting to milliliters. This gives an objective total blood loss, which helps trigger postpartum hemorrhage protocols, guide transfusion decisions, and monitor how well treatment is working. Other terms listed aren’t standard methods in obstetrics and don’t describe a real measurement approach, so they don’t fit.
