Down Syndrome: B-Test (13-22 Week, 2nd Trimester, Double Test)

Overview of Down’s Syndrome Screening

Screening for Down’s syndrome involves a series of tests designed to assess the likelihood that a developing baby has Trisomy 21, a genetic condition caused by an extra copy of chromosome 21.

Purpose of Down’s Syndrome Testing

These tests do not provide a definitive diagnosis but instead estimate the risk of the baby being born with Down’s syndrome. Early screening allows expectant parents to make informed decisions and access further diagnostic options if needed.

Common Tests Used in Screening

Nuchal Translucency Ultrasound: Measures fluid at the back of the baby’s neck during the first trimester.

Blood Tests: Assess levels of specific proteins and hormones, such as PAPP-A and β-hCG, linked to chromosomal abnormalities.

Combined First Trimester Screening: Combines ultrasound and blood test results to calculate the risk of Trisomy 21.
