Double Marker (Dual Marker) Test by Thyrocare:
The Double Marker test, also called the Dual Marker test, is a first-trimester prenatal blood screening used to estimate the risk of chromosomal conditions such as Down syndrome and Edwards syndrome. It measures PAPP-A and free β-hCG, and the result is interpreted with gestational age details and the NT scan report. This test is performed between the 8th and 13th week of pregnancy.
Free home sample collection for a dual marker test is available in 200+ cities and towns across India.

What’s Included in the Double Marker (Dual Marker) Test
Biomarkers
PAPP-A and free β-hCG from a single blood sample.
Risk calculation
The biomarker values are interpreted with gestational age and relevant maternal details to generate the screening risk estimate.
Screening output graph
Provides a risk probability, such as high-risk, medium-risk, or low-risk
Preparation for A Double Marker Test Profile
- Fasting: Not required. Stay well-hydrated.
- Gestational age (GA): Share your last menstrual period (LMP) to calculate GA.
- Documents: Keep the test requisition form (TRF) and the NT scan report ready. These help confirm whether the required screening is a double marker, triple marker, or quadruple marker test.
- Clinical context: Mention all required context, including pregnancy type (twin /ART/IVF), pregnancy history (number of children and miscarriage history, if any), and whether diabetic or not, so the lab pathway can be applied appropriately.
- Habits: Mention smoking or alcohol use, if any, because these details are relevant to risk interpretation.
- DOB: Provide the correct date of birth, because age is part of the risk calculation.

Why a Double Marker Test Is Advised in Pregnancy
The Double Marker test is used in the first trimester to screen for the risk of certain chromosomal conditions. It is advised, along with an NT scan, when early pregnancy risk assessment is needed.
This screening does not give a final diagnosis. It helps identify whether the pregnancy falls into a lower-risk or higher-risk category and whether further evaluation may be needed.
Limitation of a Double Marker Test Panel
- The Double Marker test is a screening test; it does not confirm or rule out a chromosomal condition.
- In triplet pregnancy, the Double Marker risk assessment is not possible. In twin pregnancy, risk estimation may be less accurate.
- After 13 weeks and 6 days of pregnancy, Double Marker risk estimation is not possible. In such a case, a triple marker or quadruple marker test is suggested, depending on the clinical context.
- Incorrect information in the test requisition form or patient details can affect risk calculation.
- If the report shows high risk, your obstetrician may advise follow-up options such as NIPT or amniocentesis.
