Blood Group & Genotype Test

Know your ABO blood type, Rhesus factor, and haemoglobin genotype (AA, AS, SS, AC, SC) in one visit. Essential for pre-marital planning, pregnancy care, surgery, and NYSC registration. Serving all of Lagos from our Akoka laboratory.

Two Tests, One Visit

Blood group and genotype are often required together — for pre-marital screening, NYSC medicals, and pregnancy care. We perform both in a single blood draw at our Lagos laboratory.

🅾️

ABO & Rhesus Blood Typing

Standard blood group typing identifies your ABO group (A, B, AB, O) and Rhesus status (positive or negative). Critical for blood transfusions, surgery, and — for Rh-negative pregnant women — monitoring for Rh incompatibility with the foetus.

  • ABO grouping: A, B, AB, or O
  • Rhesus typing: positive or negative
  • Same-day result in Lagos
  • Required for surgery and transfusion
🧬

Haemoglobin Genotype (Electrophoresis)

Genotyping by haemoglobin electrophoresis identifies your haemoglobin variant: AA (normal), AS (sickle cell trait), SS (sickle cell disease), AC, or SC. Two AS parents have a 25% chance of an SS child with every pregnancy — knowing your genotype before marriage enables informed family planning.

  • AA: normal — any partner compatible
  • AS: carrier — avoid AS or SS partner
  • SS: sickle cell disease
  • AC / SC: less common variants

When Results Are Required

Lagos employers, NYSC, hospitals, and immigration authorities routinely require documented blood group and genotype results. Our laboratory reports are accepted nationwide and include the clinic's stamp, date, and signatory details.

  • NYSC & pre-employment medicals
  • Pre-marital screening
  • Antenatal booking (mother & father)
  • Pre-surgery blood grouping

Serving Lagos — When Do You Need This?

💍
Pre-marital screening in Lagos Couples across Lagos Island, Lekki, Ikeja, and the Mainland test before marriage to ensure genotype compatibility and avoid sickle cell disease in their children.
🤰
Antenatal care — Rh incompatibility Rh-negative mothers carrying Rh-positive babies need anti-D prophylaxis. Blood grouping at booking identifies this risk. We serve Lagos antenatal clinics and individual patients.
💼
NYSC & Lagos pre-employment medicals NYSC registration and most formal sector employers in Lagos require documented blood group and genotype. Same-day blood group result makes appointment-day NYSC medicals easy.
🏥
Pre-surgery cross-matching Surgeons at Lagos hospitals request blood group documentation before elective procedures. Our results are printed on official laboratory headed paper.
👶
Children of AS parents Any child born to an AS parent should be genotyped. We welcome paediatric patients from across Lagos for haemoglobin electrophoresis.
Genotype Compatibility Guide
AA × AA → all children AA No sickle cell risk. Most compatible pairing.
AA × AS → 50% AA, 50% AS No sickle cell disease possible. Widely accepted pairing.
AS × AS → 25% AA, 50% AS, 25% SS 25% chance of SS child with each pregnancy. Requires genetic counselling.
SS × any → high SS risk SS paired with AS → 50% SS. Pre-implantation genetic diagnosis (PGD) may be considered.

Quick & Easy to Prepare

1

No Fasting Required

Neither blood group typing nor haemoglobin electrophoresis requires fasting. You can eat, drink, and take medications normally before your visit. Walk in at any point during our Lagos laboratory's operating hours.

2

Bring Previous Records

If you have been previously genotyped or blood-grouped and need a fresh official result, bring your prior result if available. Note: if you have received a blood transfusion recently, inform us — transfused blood can temporarily alter results.

3

Same-Day Blood Group

Blood group typing is completed in the laboratory within the hour and reported the same day. Genotype by haemoglobin electrophoresis takes 24–48 hours. Both results are available for collection or electronic delivery.

Lagos's Trusted Blood Group Laboratory

🔬
Haemoglobin electrophoresis, not just sickling test

A sickling test only identifies SS; it cannot distinguish AS from AA. We perform full electrophoresis to give you a complete and accurate genotype across all variants.

📋
Accepted nationwide

Our results are printed on official laboratory paper with stamp and signature — accepted by Lagos NYSC orientation camps, hospitals, courts, and immigration offices.

🚀
Same-day blood group result

Blood group results are ready in hours — making same-day NYSC or pre-employment medicals possible. No need to schedule a separate return visit for the blood group alone.

"We came from Lekki specifically because most labs don't do haemoglobin electrophoresis — just the sickling test. Mascot gave us a proper genotype result the next day. Totally worth the trip."
