The Double Marker test is a specialized screening test that assesses specific markers in the mother's blood to estimate the risk of certain chromosomal abnormalities, particularly Down syndrome (Trisomy 21) and Trisomy 18.

Thyrocare in Madurai ensures accurate and reliable testing results for the Double Marker - First Trimester test. This test measures two specific substances in the mother's blood: Pregnancy-associated plasma protein-A (PAPP-A) and free beta-human chorionic gonadotropin (hCG). These markers, combined with maternal age and other factors, provide important information to estimate the risk of chromosomal abnormalities in the developing fetus.

Double Marker – first Trimester FAQ

What happens if double marker test is positive?

If the double marker test is positive, it indicates an increased likelihood of certain chromosomal abnormalities, particularly Down syndrome (Trisomy 21) and Trisomy 18. However, a positive result does not provide a definitive diagnosis but rather indicates a higher risk compared to the general population. In such cases, further diagnostic tests, such as amniocentesis or chorionic villus sampling, may be recommended to confirm the presence of the chromosomal abnormality. These invasive tests can provide more accurate information about the fetal chromosomes. It is important to consult with a healthcare provider to understand the implications of a positive double marker test and to receive appropriate guidance and counseling regarding further testing and management options.

What does double marker indicate?

The double marker test is a maternal blood screening test performed during pregnancy to assess the risk of certain chromosomal abnormalities, particularly Down syndrome (Trisomy 21) and Trisomy 18. It measures two specific substances in the maternal blood: human chorionic gonadotropin (hCG) and pregnancy-associated plasma protein-A (PAPP-A). The results of the double marker test provide an indication of the likelihood of these chromosomal abnormalities in the fetus. A positive result indicates an increased risk compared to the general population, but it is not a definitive diagnosis. Further diagnostic tests, such as amniocentesis or chorionic villus sampling, may be recommended to confirm the presence of the chromosomal abnormality.

What is the risk in double marker test?

The test calculates the risk based on the measurement of two substances: human chorionic gonadotropin (hCG) and pregnancy-associated plasma protein-A (PAPP-A). The risk in the double marker test refers to the likelihood of the fetus having these chromosomal abnormalities. A higher risk result indicates an increased probability compared to the general population, but it is important to note that it does not provide a definitive diagnosis. Further diagnostic tests may be recommended to confirm the presence of the chromosomal abnormality and assess the actual risk accurately. Consulting with a healthcare provider is crucial to interpret the results and discuss any necessary follow-up actions.
