Description
Why It’s Done:
The Triple Marker Test is a screening tool used to evaluate the likelihood of fetal abnormalities, such as:
• Down syndrome (Trisomy 21)
• Trisomy 18 (Edwards syndrome)
• Neural tube defects like spina bifida and anencephaly
Preparation:
• No fasting or special preparation is needed.
• A blood sample will be drawn from a vein in your arm.
• Inform your doctor of your exact gestational age, weight, ethnic background, and whether you’re carrying more than one baby, as these factors influence the interpretation of the results.
