DOUBLE TEST FOR DOWN SYNDROME SCREEN TEST

What is a Double Test for Down Syndrome Screening?

A Double Test for Down Syndrome Screening is a prenatal blood test performed during the first trimester of pregnancy to assess the risk of certain chromosomal abnormalities in the baby, including Down syndrome (Trisomy 21) and Edwards syndrome (Trisomy 18).

The test measures two important markers in the mother's blood and is usually done between 11 and 14 weeks of pregnancy. It is often combined with an ultrasound scan called the Nuchal Translucency (NT) scan to provide a more accurate risk assessment.

It is important to understand that this is a screening test, not a diagnostic test. It estimates the likelihood of a condition but does not confirm whether the baby has a chromosomal disorder.

Double Test for Down Syndrome Screening Parameters

The Double Test typically includes:

• Free Beta Human Chorionic Gonadotropin (Free β-hCG) – Measures the level of pregnancy hormone in the mother's blood.
• Pregnancy-Associated Plasma Protein A (PAPP-A) – Evaluates a protein produced by the placenta during pregnancy.

These results, along with the mother's age, gestational age, and NT scan findings, help calculate the risk of chromosomal abnormalities.

8 Reasons Your Doctor May Recommend a Double Test

Your doctor may advise a Double Test for Down Syndrome Screening if:

• You are between 11 and 14 weeks pregnant.
• You are 35 years of age or older.

• You conceived through fertility treatment.
• The NT scan shows increased nuchal thickness.
