The Complete Guide to Pre-Marriage Screening in Kano: Genotypes, Rhesus Compatibility & Viral Safety
Why comprehensive pre-marital diagnostic screening is vital for couples in Kano State, from understanding Sickle Cell hemoglobin electrophoresis (AA, AS, SS) to preventing Rhesus incompatibility.

1. Hemoglobin Genotype: Preventing Sickle Cell Disease
Hemoglobin electrophoresis identifies the specific hemoglobin variants present in red blood cells. The standard normal hemoglobin is HbA, while the mutated sickle hemoglobin is HbS and HbC.
When two sickle cell trait carriers (AS + AS or AS + AC) conceive, there is a 25% chance in each pregnancy that the child will inherit Sickle Cell Anemia (SS or SC disease). Automated hemoglobin electrophoresis and high-performance liquid chromatography (HPLC) performed at Klinchex eliminate ambiguity, providing absolute certainty on AA, AS, AC, and SS statuses.
- AA + AA: 100% compatible with no genetic sickle cell risk.
- AA + AS / AC: Safe combination — no child can develop full sickle cell disease.
- AS + AS or AS + AC: High genetic risk (1 in 4 chance of SS per pregnancy); urgent genetic counseling required.
2. Blood Group and Rhesus (Rh) Incompatibility
Rhesus factor is an inherited protein on the surface of red blood cells. If a prospective bride is Rh-negative (e.g., O-, A-) and her partner is Rh-positive, the mother may develop anti-D antibodies during a first pregnancy with an Rh-positive fetus.
Without medical awareness, subsequent pregnancies risk Hemolytic Disease of the Fetus and Newborn (Erythroblastosis Fetalis). Identifying Rh status before marriage allows timely administration of anti-D immunoglobulin (RhoGAM) during pregnancy and immediately post-delivery, ensuring safe, healthy childbearing.
3. Viral Hepatitis B, Hepatitis C, and Retroviral Status
Chronic viral hepatitis B (HBsAg) and hepatitis C (HCV) are highly prevalent in Sub-Saharan Africa and can be transmitted sexually or horizontally within households. Knowing a partner’s status allows the non-infected partner to complete the 3-dose Hepatitis B vaccination series with confirmed immune protection.
Similarly, early confidential retroviral screening (RVS / HIV 1 & 2) ensures both partners know their status. With modern anti-retroviral therapy (ART), individuals with undetectable viral loads live full, healthy lives with zero risk of sexual transmission (U=U).
- Hepatitis B Surface Antigen (HBsAg) with vaccine recommendations
- Hepatitis C Virus (HCV) antibody verification
- Confidential Retroviral Screening (RVS / HIV 1 & 2)
- Syphilis Serology (VDRL / RPR)
4. Reproductive Baseline & Microbial Health
Pre-marital screening at Klinchex also includes basic baseline microbial checks: Urinalysis and Urine Culture to detect asymptomatic urinary tract infections, High Vaginal Swabs (HVS) for prospective brides, and Semen Analysis (WHO parameters) where requested to assess fertility baselines.
