What is a Carrier Screening Test?

Carrier screening is a genetic test that identifies individuals who carry pathogenic variants associated with autosomal recessive disorders. Carriers are typically asymptomatic, as they possess one normal and one mutated allele. However, if both partners carry variants in the same gene, there is a 25% risk in each pregnancy of having an affected child, making carrier screening essential for accurate reproductive risk assessment and informed decision-making.

Screening for Inherited Genetic Conditions

Inherited genetic conditions occur when specific gene mutations are passed from parents to children. While individually rare, these conditions are collectively common.

Common Conditions Screened For

 
  • Depending on the panel selected (Ethnic-Based vs. Expanded), we screen for disorders including:
  • 1.Cystic Fibrosis (CF) , Spinal Muscular Atrophy (SMA), Sickle Cell Disease, Tay-Sachs Disease, Thalassemia.
  • 2. Expanded Carrier Screening (ECS): Modern technology now allows us to screen for over 100+ conditions simultaneously, regardless of ethnicity, providing a more comprehensive risk assessment than traditional ethnicity-based panels.

Who should consider this test?

  1. As per current guidelines from ACOG and ACMG, couple carrier screening is recommended for:
  2. Couples planning a pregnancy (preconception stage), as this provides the widest range of reproductive options.
  3. Couples who are already pregnant and wish to assess the risk of genetic conditions in the baby.
  4. Individuals or couples with a known family history of genetic disorders, even in distant relatives.
  5. Egg or sperm donors, to minimise the risk of passing inherited conditions to offspring.
  6. Couples belonging to ethnic groups with a higher prevalence of specific genetic disorders.
  7. Any couple seeking proactive reproductive planning, especially considering increasing genetic diversity and unknown ancestry.

Frequently Asked Questions

Not really. Most carriers have no family history at all. These conditions can stay silent for generations until both partners unknowingly carry the same gene.

Usually, one partner is tested first. If they are a carrier, then the other partner is tested. But testing both together saves time and gives a clearer picture faster.

Not at all. It’s still useful during pregnancy to understand risks early and plan the next steps with proper medical guidance.

You’re not stuck you get options. This could include further testing during pregnancy, IVF with genetic testing, or simply being better prepared. The goal is informed decisions, not panic.

Earlier, yes. But now, with mixed ancestry and mobility, that approach misses risks. Expanded screening looks beyond ethnicity, which makes it more relevant today.

Sudden cardiac arrest (SCA) is one of the most devastating cardiovascular emergencies. SCA happens when the electrical system of the heart malfunctions, resulting in deadly arrhythmias, as opposed to a heart attack, which is brought on by limited blood supply to the heart muscle.
