Quadruple Test (Quad Marker) Test

NRS. 5600

NRS. 5800


Maternal Screen 4 Quad marker with graph test (from 14 to 22 weeks of pregnancy)


Maternal Screen 4 Quad marker with graph test (from 14 to 22 weeks of pregnancy) for pregnant women as this test to classify a patient as either high-risk or low-risk for chromosomal abnormalities (Down Syndrome-Trisomy 21, Edward’s Syndrome-Trisomy 18) and neural tube defects. It identifies the risk of the baby being affected.

This test is done between 14 and 22 weeks of pregnancy. However, the best time for this test is between 15 and 20 weeks of pregnancy.

The approximate detection rate with this test is 75-80 % with a false positive rate of 5%.

This test not only for women of age 35 years or more. Every pregnant woman is advised to take this test, for detecting any abnormality in the fetus before birth.

Tests Parameter to check for:

This test measures the levels of four marker AFP, Unconjugated Estriol, β -HCG and inhibin A in blood, so known as the Quad Marker test.

·       AFP is a protein which is produced by the fetus. If the levels of AFP are high, it indicates neural tube defects in the fetus or there can be incomplete closure of the fetus abdomen.

·       HCG hormone is produced by cells of the placenta. If the levels of HCG are low, it indicates a miscarriage or ectopic pregnancy. Whereas, if the levels of HCG are high this indicates multiple pregnancies.

·       Estriol is a form of the hormone estrogen which is present in both fetus and placenta. If the levels of estriol are low, it indicates the risk of the baby getting delivered with Down syndrome especially when the levels of AFP are low and HCG are high.

·       Inhibin A is a hormone which is produced by the placenta. It is a dimer which means it has two parts. It is also sometimes referred to as DIA or dimeric inhibin A. In the 14 to 17 weeks of gestation (pregnancy), the levels of inhibin A in maternal blood slightly decrease and then rise again. Increased levels of Inhibin A indicate fetus with Down syndrome. Inhibin A enhances the sensitivity as well as the specificity in order to correctly identify cases of Down syndrome.

Recommended for

Females who are 35 years or more, have a family history of birth defects, or have diabetes or are using insulin have a higher risk of getting abnormal values of these markers. Exposure to high levels of radiation or having the viral infection during pregnancy can also be considered as possible risk factors associated with these high levels. This test is also helpful to indicate any complications in the fetus after birth.
