Double Marker (fmf Approved)

The Double Marker Test is a first-trimester screening for chromosomal abnormalities in the fetus, particularly Down syndrome (Trisomy 21) and Trisomy 18. It measures two key markers: free beta-hCG and PAPP-A (pregnancy-associated plasma protein A).

• It helps screen for fetal anomalies early in pregnancy, particularly Down syndrome and Trisomy 18, both of which can result in developmental delays and physical abnormalities.
• It allows for early intervention and counseling for the parents, and can also guide decisions about further testing (such as amniocentesis or CVS).

• Pregnant women in their first trimester (usually between 11 to 14 weeks of gestation).
• Particularly recommended for older women (over 35), or those with a family history of genetic disorders.

The test is non-invasive and offers an early assessment of the risk of chromosomal abnormalities, although it is not diagnostic. If results suggest high risk, further invasive testing may be recommended.
