Answer: for trisomy triple marker test is performed to know more about chromosomal abnormalities in fetus. the result shows how risky is at fetus to have such abnormalities. Triple marker test is the extension of double marker and looks for AFP, hCG, and Estriol. AFP: alpha-fetoprotein is a protein that is produced by the fetus. hCG: human chorionic gonadotropin is a hormone produced within the placenta Estriol: estriol is an estrogen produced by both the fetus and the placenta The triple screen test is performed between the 15th and 20th week of pregnancy. Low levels of AFP and abnormal levels of hCG and estriol may indicate that the developing baby has Trisomy 21, Trisomy 18 or another type of chromosome abnormality.
