Maternal Serum Screening
Down Syndrome, Trisomy 18 and Neural Tube Defects
Second Trimester Screening
March 2011
Second trimester screening using these 4 markers is the best option for women presenting for prenatal care later in the pregnancy.
Second trimester screening tends to have a slightly lower detection rate for Down syndrome compared to first trimester. In addition, since risk information is not available until the second trimester, the time for counseling and follow-up testing is limited.
