Carrier Screening 100 Genes Couple

Carrier screening for couples checks both partners for changes in 100 genes linked to inherited recessive conditions. It helps couples understand the chance of passing a condition to their children, ideally before pregnancy.

What the test looks for

Most people carry a few harmful gene variants without knowing it, because one working copy of the gene is enough to stay healthy. A child is affected by a recessive condition only when they inherit a changed copy of the same gene from both parents.

This test screens 100 genes in both partners. It is most useful when both partners are tested together, because what matters is whether you both carry a variant in the same gene.

Who might consider it

• Couples planning a pregnancy, including those with no family history
• Couples who are blood relatives (for example, cousins), as they are more likely to carry the same variants
• Couples with a family history of an inherited condition, or who have had an affected child

Before you book

A doctor’s prescription is needed for this test, together with the medical and family history of both partners. Each partner gives one blood sample. Our team can collect the samples at your home anywhere in Dubai, or you can both visit our lab in Al Karama or Al Barsha 1. The lab also asks each partner for a signed consent form. Results are usually ready in 4–6 weeks.

Understanding your results

• No shared carrier status: neither of you carries a variant in the same gene, so the chance of an affected child for the screened conditions is low. No screen can cover every condition.
• Both partners carry a variant in the same gene: each pregnancy has a 1 in 4 chance of an affected child. A genetic counsellor will explain the condition and your options.
• One partner is a carrier: this is common and usually does not change the risk for the screened conditions, but your doctor will explain it.

Results should always be explained by a doctor or genetic counsellor.
