Maternal Serum Screening
Overview
Maternal Serum Screening is a blood test offered to pregnant women who want to find out if they may be at increased risk of having a baby with Down syndrome, trisomy 18 or neural tube defects (such as spina bifida). There are two Maternal Serum Screening tests that are offered to Victorian women during pregnancy; Combined First Trimester Screening (CFTS) and Second Trimester Screening (2TMSS).
Combined First Trimester Screening can also provide useful information for the management of a pregnancy, such as your risk of early-onset Pre-clampsia.
