What is a Double marker test?

Double marker test is done to get early information about a baby's risk of having certain abnormalities. Small fragments of DNA from placenta circulate in women’s blood during pregnancy. DNA from the fetus and mother is extracted from maternal blood samples. Collecting and analyzing these DNA fragments helps detect any possible genetic abnormalities without harming the fetus. The DNA in the placental cell is usually identical to the babies. Double marker test is used to detect chromosomal disorders like down syndrome, trisomy 18, trisomy 13 and missing sex chromosomes. Double marker test can also reveal the gender of the baby.It is mostly done in women who are at higher risk of carrying a baby with birth defects, usually after 10th week of pregnancy.
