What is Genetic Screening?

Genetic screening is a medical test that analyzes your DNA to identify changes (mutations) in your chromosomes or genes. In the context of reproductive health, it is used to determine the risk of a couple passing on a hereditary condition to their offspring.

It is important to distinguish between two types of genetic tests:

• Screening Tests: These assess the probability or risk of a condition. They are non-invasive and offered to individuals who do not necessarily have a family history of disease.
• Diagnostic Tests: These provide a definitive "yes" or "no" answer. They are usually performed if a screening test comes back as "high risk" or if there is a known genetic issue in the family.

Key Types of Genetic Screening

At Ashoka Women & Children Hospital, we offer genetic insights at every stage of your journey toward parenthood:

1. Carrier Screening (Pre-Marital & Pre-Conceptional)

This is performed on the parents before pregnancy. Many severe conditions, such as Thalassemia, Cystic Fibrosis, and Spinal Muscular Atrophy (SMA), are autosomal recessive. This means a child only develops the disease if they inherit a mutated gene from both parents.

• The Benefit: If both partners are identified as carriers of the same condition, our specialists can guide you through options like IVF with genetic testing to ensure the disease is not passed on.

2. Non-Invasive Prenatal Testing (NIPT)

Performed as early as the 10th week of pregnancy, NIPT is a highly advanced blood test for the mother. It analyzes tiny fragments of fetal DNA that circulate in the mother's bloodstream.

• What it Detects: NIPT is exceptionally accurate at screening for chromosomal abnormalities, including Down Syndrome (Trisomy 21), Edwards Syndrome (Trisomy 18), and Patau Syndrome (Trisomy 13). Because it only requires a simple blood draw from the mother, it poses zero risk to the baby.

3. First-Trimester Screening (Double Marker Test)

This combined screening involves a maternal blood test and a specialized ultrasound called an NT Scan (Nuchal Translucency). Our Fetal Medicine experts measure the fluid-filled space at the back of the baby's neck. Increased thickness can be an early indicator of chromosomal issues or heart defects.

4. Preimplantation Genetic Testing (PGT)

For couples undergoing IVF Treatment, we can screen embryos for genetic abnormalities before they are transferred to the uterus. This is highly recommended for couples with a history of recurrent miscarriages, advanced maternal age, or known hereditary disorders.

Who Should Consider Genetic Screening ?

While genetic screening is available to all couples, it is strongly recommended if:

• You have a family history of genetic disorders or birth defects.
• The mother is over the age of 35 (increased risk of chromosomal issues).
• The couple has experienced recurrent miscarriages or a previous stillbirth.
• You belong to an ethnic group with a higher prevalence of certain genetic traits (e.g., Thalassemia).
• You and your partner are blood relatives (consanguineous marriage).
