A gynecologist may recommend the dual or double marker test to pregnant women, typically between 9 to 13.6 weeks of gestation during the first trimester. This screening test is used to assess the risk of the baby having certain chromosomal abnormalities, including:
Down Syndrome (Trisomy 21)
Trisomy 18 (Edwards Syndrome)
The test measures specific markers in the mother's blood to estimate the risk of these conditions. If the screening test indicates a high risk of abnormalities, a more definitive test, such as Chorionic Villus Sampling (CVS), may be recommended to confirm the diagnosis. The dual marker test is an important tool for early risk assessment, allowing for informed decisions and timely medical interventions if needed.
