Description
AFP, HCG, Free Estriol, Inhibin (14-21 weeks) second trimester
Sample Type:Serum
Tests Included:
The Quadruple Test is often used in pregnancy and includes measurements of alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), unconjugated estriol (uE3), and inhibin A.
Sample Required:
Blood sample collection for this test.
Test Time:
Results are usually available within a few days after sample collection.
Test Range Values:
Results are reported based on the levels of AFP, hCG, uE3, and inhibin A, helping estimate the risk of Down syndrome and other chromosomal abnormalities.
What is the test?
This test in pregnancy assesses the risk of Down syndrome and other chromosomal abnormalities by measuring specific proteins and hormones in maternal blood.
Test Procedure:
Blood is drawn from the pregnant individual, and the levels of AFP, hCG, uE3, and inhibin A are measured in the laboratory.
When to take the test:
Recommended between weeks 15 and 20 of pregnancy for Down syndrome screening.
Who should take the test:
Pregnant individuals, especially those at higher risk or with specific concerns about fetal chromosomal abnormalities, might consider this test.
Precautions for exceptional cases (pregnancy, etc.):
The Quadruple Test is a screening test and might not provide a definitive diagnosis. Further invasive tests might be recommended based on the results.
Frequently Asked Questions (FAQs) for Quadruple Test in Pregnancy:
Q1: Is the Quadruple Test more accurate than other prenatal tests?
A: The Quadruple Test is a screening test and has a certain level of accuracy in estimating the risk of chromosomal abnormalities but is not as definitive as invasive tests like amniocentesis.
Q2: What does a high or low result in the Quadruple Test indicate?
A: Abnormal levels in the Quadruple Test might indicate an increased risk for chromosomal abnormalities, but further testing is required for confirmation.
Q3: Are there factors that might affect Quadruple Test results?
A: Various factors, including maternal age, gestational age, multiple pregnancies, or certain medications, might influence the results of the Quadruple Test.
Q4: Is the Quadruple Test mandatory during pregnancy?
A: The Quadruple Test is optional and considered in pregnancies where individuals want information about the risk of chromosomal abnormalities.
Q5: Can the Quadruple Test pose risks to the pregnancy or the fetus?
A: The Quadruple Test is a non-invasive screening test and generally poses no risks to the pregnancy or the fetus.
