  • Free Beta HCG
  • PAPP-A (Pregnancy-Associated Plasma Protein A)

What does this test Double Marker Test identify?

The Double Marker Test is a blood test that is used to identify certain genetic disorders in a developing fetus. This test is typically done between 8 and 14 weeks of pregnancy and looks for specific markers in the mother's blood that may indicate an increased risk of certain conditions.

  • Identifies risk of Down syndrome: The test looks for markers that may indicate an increased risk of Down syndrome, a genetic disorder caused by the presence of an extra chromosome 21.
  • Identifies risk of neural tube defects: The test can also detect markers that may indicate an increased risk of neural tube defects, such as spina bifida.
  • Identifies risk of other chromosomal abnormalities: In addition to Down syndrome, the Double Marker Test can also identify markers that may indicate an increased risk of other chromosomal abnormalities, such as trisomy 18.

Why is this test Double Marker Test taken?

The Double Marker Test is a blood test that is taken during pregnancy to screen for certain genetic disorders and assess the risk of chromosomal abnormalities in the fetus. It is usually recommended for pregnant women who are at a higher risk of having a baby with a genetic disorder, such as women over the age of 35, those with a family history of genetic disorders, or those who have had a previous pregnancy with a genetic abnormality.

The test measures the levels of two substances in the mother's blood - hCG (human chorionic gonadotropin) and PAPP-A (pregnancy-associated plasma protein A). Abnormal levels of these substances can indicate an increased risk of certain chromosomal abnormalities, such as Down syndrome.

The Double Marker Test is not a definitive diagnosis of a genetic disorder, but it can help identify women who may benefit from further testing, such as amniocentesis or chorionic villus sampling, to confirm the presence of a genetic abnormality.

A Double Marker Test is a blood test that is performed during pregnancy to assess the risk of certain chromosomal abnormalities in the baby, such as Down syndrome and neural tube defects.
The Double Marker Test is typically done between 9 to 13 weeks of pregnancy, although it can be done up to 20 weeks.
The Double Marker Test involves taking a blood sample from the mother, which is then analyzed for levels of two specific proteins - PAPP-A and free beta hCG.
While the Double Marker Test is a screening test and not a diagnostic test, it is considered to be highly accurate in assessing the risk of chromosomal abnormalities in the baby.
The results of the Double Marker Test indicate the likelihood of the baby having certain chromosomal abnormalities, with a higher level of the proteins indicating a higher risk.
