Procedure - Percutaneous Umbilical Cord Sampling
If you are at risk for having a baby with a genetic defect or blood disorder, your doctor may recommend percutaneous umbilical cord blood sampling (PUBS), which is performed at 18 weeks' gestation.
During the procedure, the doctor draws a sample of the fetus' blood directly from the umbilical cord. The sample is then analyzed for genetic defects and other health conditions.
