Carrier screening

Testing to check whether a person carries a gene change for a recessive condition.

Genetics & PGT

Carrier screening is genetic testing offered to individuals or couples, usually before or in early pregnancy, to check whether they carry a variant for a recessive genetic condition that could affect a future child if both partners carry a change in the same gene. In India, screening for haemoglobin disorders such as beta-thalassaemia and sickle-cell disease is particularly relevant given their prevalence in many populations and regions, and some clinics also offer screening panels covering conditions such as spinal muscular atrophy. Carrier screening does not test for every possible genetic condition, and a 'low risk' result reduces but does not eliminate the chance of an affected child. Not everyone needs the same screening panel — relevance depends on family history, community background and personal preference, and results are best discussed with a genetic counsellor who can explain what a positive or carrier result means for reproductive planning.

Also known as: genetic carrier testing, preconception genetic screening, thalassaemia carrier screening
