What is Double Marker?
This blood test is typically performed during the first trimester of pregnancy to screen for potential chromosomal abnormalities in the fetus. It measures the levels of two specific hormones, free beta-hCG and PAPP-A, in the mother's blood. The results help assess the risk of conditions like Down syndrome and Edward's syndrome.
Why is this test important?
The Double Marker test is a crucial screening tool that, when combined with an ultrasound nuchal translucency measurement, provides a more comprehensive risk assessment. It helps healthcare providers identify pregnancies that may require further diagnostic testing, allowing for informed decisions and early intervention if necessary.
