Dual Marker Screening
Dual marker screening is a first-trimester prenatal blood test that measures two biochemical markers. It is commonly interpreted together with maternal age, gestational information, and a nuchal-translucency ultrasound to estimate the chance of selected chromosomal conditions.
What the Result Means
The result is a chance estimate, not a diagnosis. A higher-chance result does not confirm a chromosomal condition, and a lower-chance result does not exclude every genetic or developmental condition.
Timing and Clinical Information
The test is performed during a specific first-trimester collection window. Accurate gestational dating and complete clinical information are important. Your obstetric clinician will advise the appropriate timing.
Possible Next Steps
Your clinician may discuss ultrasound, cell-free DNA screening, genetic counselling, or diagnostic testing based on the result and the wider clinical picture.
