Health Advocates for Genotype Screening Before Marriage

A single blood test before marriage. Advocates say it could spare countless Nigerian families from a lifetime of preventable suffering.

Health advocates have called for mandatory genotype screening before marriage as part of broader efforts to reduce the incidence of sickle cell disease and prevent avoidable family crises across Nigeria. The call, made during discussions in Abuja, reflects growing concern that without systematic premarital screening, the country continues to see preventable cases of a condition that already places significant strain on families and the healthcare system.

Why Genotype Screening Matters

Sickle cell disease occurs when both parents carry the sickle cell trait, passing it on to their children in its most severe form. Advocates explained that genotype screening remains one of the most effective strategies for reducing the burden of sickle cell disease, since couples who learn of incompatible genotypes before marriage can make informed decisions about their reproductive futures.

Nigeria carries one of the highest global burdens of sickle cell disease, with the condition contributing significantly to childhood morbidity and mortality. Furthermore, families affected by the disease often face substantial financial and emotional strain managing a chronic condition that requires lifelong medical attention.

The Case for Mandatory Policy

While genotype testing is already widely encouraged in Nigeria, particularly within religious and cultural marriage traditions, it remains voluntary rather than legally mandated. Advocates argue that a formal policy requiring screening before marriage registration could significantly increase awareness and compliance, particularly in communities where the practice is not yet firmly established.

Such a policy would need careful implementation to avoid stigmatising individuals who carry the sickle cell trait, since carrying the trait does not mean having the disease itself. Consequently, any mandatory screening framework would need to be paired with comprehensive public education to ensure accurate understanding among the general population.

A Preventable Crisis, If Acted On Early

Unlike many of Nigeria’s current public health challenges, sickle cell disease prevention through screening represents a problem with a relatively straightforward, low cost solution available right now. The challenge lies not in medical complexity but in policy implementation, public awareness, and ensuring screening facilities are accessible across both urban and rural communities.

For the advocates pushing this agenda, the message is clear. Every couple who learns their genotype compatibility before marriage represents one less family that might otherwise face the heartbreak of raising a child with a severe, lifelong health condition that could have been anticipated and discussed in advance.
