The maternal blood screen is a simple blood test. It measures the levels of two proteins, human chorionic gonadotropin (hCG) and pregnancy associated plasma protein A (PAPP-A). If the protein levels are abnormally high or low, there could be a chromosomal disorder in the baby.
Can blood test detect abnormalities in pregnancy?
Non-Invasive Prenatal Testing (NIPT) screening: This cell-free fetal DNA test can be done as early as after 10 weeks of pregnancy. The test uses a blood sample to measure the relative amount of free fetal DNA in a mother’s blood. It’s thought that the test can detect 99% of all Down syndrome pregnancies.
When can abnormalities be detected in pregnancy?
Major abnormalities of the fetal head, abdominal wall and urinary tract, and of the umbilical cord and placenta, can be reliably detected at 10-11 weeks of gestation. Detection of other anomalies such as spina bifida, diaphragmatic hernia or heart defects is limited before 13 weeks of gestation.
What do pregnancy blood tests show?
You can expect to receive routine bloodwork during your pregnancy that checks for: Your hCG levels. A blood test for hCG can detect pregnancy with more than 99 percent accuracy as early as one week after conception. A qualitative pregnancy blood test simply looks for any hCG in your bloodstream to confirm pregnancy.

Can a blood test show how many weeks pregnant you are?
Quantitative blood test – measures the exact amount of hCG in the blood and can give you an estimate of how far along the pregnancy has progressed. Qualitative blood test – only checks for the presence of hCG. Since this test doesn’t measure the exact levels of hCG, it can’t offer an estimate of gestation.
How do you test for fetal abnormalities?
Amniocentesis. An amniocentesis involves taking a small sample of the amniotic fluid that surrounds the fetus. It is used to diagnose chromosomal disorders and open neural tube defects, such as spina bifida.
