Frequently Asked Questions (FAQ's)

A double or dual marker test screening is conducted during the first trimester of pregnancy. It is a part of a full-fledged screening panel that is conducted between the 8th and 14th weeks of gestation. The purpose of a double marker test is to detect neurological abnormalities in the foetus. The results of this blood test are given in the form of ratios that you can correlate with the ranges provided in the report. “Screen positive” of a double marker test means that the foetus is in a high-risk zone while “screen negative” indicates that there are minimal or no risks involved. It is extremely essential that you choose a reputed lab to get these tests done for accurate results.

A Nuchal Translucency Scan or NT scan is an abdominal ultrasound, recommended for pregnant women between the 13th and 15th weeks of gestation. This ultrasound scan helps in detecting chromosomal abnormalities in the foetus. In the case of a double marker test, a blood sample is taken between the 8th and 14th weeks of gestation. This blood test also helps in detecting chromosomal abnormalities by measuring the levels of free beta hCG and Pregnancy Associated Plasma Protein (PAPP-A). An NT scan and a double marker test are done simultaneously in order to get a comprehensive screening during pregnancy. 

A double or dual marker test is prescribed to pregnant women during the first trimester of gestation. The main purpose of this blood test is to detect chromosomal abnormalities in the foetus. There is a very short window of time to get this test done in order to get the most accurate results. This period is between the 8th and 14th weeks of gestation. So, an OB/GYN will recommend a dual marker test in pregnancy during the end of the first trimester or the beginning of the second trimester. 

No, it is not possible to predict the gender of the foetus with a double marker test. This is because this blood test is conducted between the 8th and 14th weeks of gestation for determining chromosomal abnormalities. Not only is it difficult to know the gender during this period, but it is illegal to provide this information in India. So, pregnant women or their families cannot find out about the gender of the foetus with this blood test or any other screening test. Reputed pathologists, as well as medical practitioners, do not provide information about gender. 

When the test reports are provided to the patient, the results can either be “screen positive” or “screen negative”. A “screen positive” in a double marker test means that the foetus may be at a high risk of chromosomal abnormalities. In case there is a false-positive test result, then the chances of such neurological conditions may or may not be present upon birth. Since this blood test is conducted early on, parents can make a sound decision about the pregnancy based on the test results. 

A double market test helps in determining whether the foetus has neurological defects like Down syndrome, Edward’s syndrome, Patau’s syndrome, etc. When the report states “screen negative” in a double marker test, this means that the foetus is at low risk of chromosomal abnormalities. This means that the test results are in the normal range, so further testing will only be required if this is a family history or any other medical condition. 

No, the sample collection of a double marker test does not require fasting. So, there is no requirement for being empty stomach for this blood test. But if you feel any confusion regarding this, then it is best to contact Max Lab’s helpline before giving your blood sample. Another way to resolve this query is by speaking with a physician or OB/GYN in your city or town. 

The time taken to provide the report of a double marker test may vary between three days to a week. Max Lab ensures that the time duration of a double marker test report does not take more than two days after sample collection. Whether the test is conducted at a diagnostic centre of Max Lab or the sample is collected at your residence, the reports are provided on time.
