Quad screen: This is a blood test usually done between 15 and 20 weeks of pregnancy. It tries to calculate the risk of the baby having down's syndrome, another genetic disorder called trisomy, or open spina bifida. It cannot tell you for sure if the baby has these, just if you are at increased risk. There are definitely some false negatives (rare) and false positives (common).

QUAD screen.: Historically performed between 16-20 weeks, the maternal serum quadruple screen (quad) is likely to fall by the wayside now that cell-free fetal dna can actually be tested from the maternal blood (maternit21 and others). Quad is a screening - not diagnostic - test.
