Triple screen test during first trimester of pregnancy

The Triple test is a screening test used to estimate the risk for the baby to be born with a genetic anomaly. It requires a bloodwork to be performed on weeks 10-12 of pregnancy, as well as to determine the levels of beta-hCG hormone and protein PAPP-A. On the other hand, the nuchal fold is measured by ultrasound scan. These three values, along with other parameters such as maternal age and weight, are combined to perform the triple test, hence the name.
