PUBS stands for which procedure?

• A. Percutaneous Umbilical Blood Sampling
• B. Postnatal Umbilical Blood Sampling
• C. Percutaneous Uterine Biopsy Sampling
• D. Prenatal Umbilical Biopsy Sampling

Answer: (A)

PUBS is a prenatal procedure used to obtain fetal blood for rapid diagnostic testing by sampling from the umbilical vein. It is performed percutaneously—through the mother's abdomen—under ultrasound guidance, typically in the second trimester, and can also be used for intrauterine transfusion when needed. The term exactly describes the method and target: Percutaneous Umbilical Blood Sampling. This distinguishes it from procedures done after birth (postnatal sampling), or from sampling that would biopsy uterine tissue or umbilical tissue rather than drawing fetal blood. It’s also known as cordocentesis, but the essential idea is obtaining fetal blood via the umbilical vein.
