Frequently asked questions

To determine the likelihood that the foetus may have chromosomal abnormalities, such as
Down syndrome, a blood test called the double marker test is often performed between 11
and 13 weeks of pregnancy.

A little amount of blood is drawn for the test from an arm vein. The material is delivered to a
lab for evaluation.

Human chorionic gonadotropin (hCG) and pregnancy-associated plasma protein A
(PAPP-A) levels in the mother's blood are determined by the test (hCG). During pregnancy,
these markers are created by the placenta and are found in the mother's blood.

The test is not entirely accurate, and a screen-negative outcome does not ensure that the
foetus does not have a chromosomal issue. When a test misses an anomaly even though it
is present, this is known as a false-negative result.

No, the test is optional, and the choice to undergo it should be made based on your unique
circumstances after you and your healthcare professional have talked about the risks and

It is risk-free and safe to perform the double marker test. A false-positive test result might
result in undue anxiety and more testing, which is the main danger involved.

If the test results are positive, it signifies that the test has found an elevated risk of
chromosomal abnormalities, and additional diagnostic testing, such as chorionic villus
sampling (CVS) or amniocentesis, may be suggested.
