The starting point of diagnosis of Downs Syndrome is a simple assessment of the mother as early as 3rd month of pregnancy by a blood test to measure the levels of certain pregnancy hormones in the mother’s blood (The Double Marker Test). At the same time, a further review of the baby through an ultrasonography examination is done (The Nuchal Translucency Scan), which assesses the fluid at the back of the baby’s neck All babies will have some fluid here, but in babies with Downs syndrome the fluid tends to be increased. The most accurate way of estimating the risk is by combining the information from mother’s age, nuchal scan & double marker test in an internationally patented software (Perkin Elmer System) to detect up about 90% of the babies with Downs syndrome & other Chromosomal Disorders.
