Quadruple Marker Second Trimester Test in Madurai
Thyrocare, a trusted healthcare service provider, offers the Quadruple Marker Second Trimester test in Madurai providing expectant mothers with important information about the health and development of their baby during the second trimester of pregnancy. The Quadruple Marker test is a specialized screening test that assesses specific markers in the mother's blood to help identify the risk of certain chromosomal abnormalities and neural tube defects in the developing fetus.
The Quadruple Marker Second Trimester test offered by Thyrocare in Madurai measures four specific substances in the mother's blood: alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), unconjugated estriol (uE3), and inhibin-A. These markers, combined with the mother's age, gestational age, and other factors, help estimate the risk of conditions such as Down syndrome, trisomy 18, neural tube defects, and other chromosomal abnormalities.
Quadruple Marker Second Trimester FAQ
When is the ideal time for quadruple marker?
The ideal time for a quadruple marker test is typically between the 15th and 20th week of pregnancy. This test is a maternal blood screening test that assesses the levels of four substances: alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), unconjugated estriol (uE3), and inhibin A. The quadruple marker test is used to evaluate the risk of certain chromosomal abnormalities, particularly Down syndrome (Trisomy 21) and neural tube defects. Performing the test within the recommended time frame allows for accurate results and provides expectant parents with valuable information about the health of the fetus, helping them make informed decisions about their pregnancy and any necessary follow-up testing or interventions.
What is the normal range of quadruple marker test?
The normal range for the quadruple marker test can vary slightly depending on the laboratory and the gestational age at which the test is conducted. However, generally, the following ranges are considered normal:
- Alpha-fetoprotein (AFP): 10-150 ng/mL
- Human chorionic gonadotropin (hCG): 15,000-60,000 mIU/mL
- Unconjugated estriol (uE3): 0.5-3 ng/mL
- Inhibin A: 0.5-2.5 ng/mL
What is the age risk for quadruple marker test?
The age risk for the quadruple marker test refers to the association between a woman's age and the risk of certain chromosomal abnormalities, particularly Down syndrome (Trisomy 21). Advanced maternal age, typically defined as 35 years or older at the time of delivery, is considered a risk factor for chromosomal abnormalities. The quadruple marker test is often recommended for pregnant women, regardless of age, to assess the risk of these abnormalities. However, the age of the mother is an additional factor that healthcare providers consider when interpreting the test results. Advanced maternal age is associated with an increased likelihood of abnormal test results, and further diagnostic testing, such as amniocentesis or chorionic villus sampling, may be recommended to confirm or rule out any potential chromosomal abnormalities.
