Triple screening

Triple screening refers to a screening blood test that is used to screen pregnant women for possible neural tube defects, Down syndrome and trisomy 18 in the developing baby. It measures:

An abnormal test result doesn't indicate a birth defect, it could be because of a disparity in the estimated gestational age, similarly not all defects can be detected by this test.

Triple screens are most accurate between the 16th and the 18th weeks; however they may be done between 15th and 22nd weeks. 

If found abnormal further ultrasound screening and amniocentesis may be suggested.
