Haematological parameters and haemoglobin genotype in maternal and cord blood pairs in Port Harcourt, Nigeria
Background: The study was conducted to ascertain the pattern of haematological parameters and haemoglobin genotype in maternal and cord blood pairs in the Port Harcourt area of the South-South geopolitical zone of Nigeria. Methods: One hundred and three (103) postpartum women and their newborns were randomly recruited into the study. Five millilitres (5ml) of blood was taken from the mothers and their respective babies and analyzed for haematological parameters and haemoglobin genotype. Results: Haemoglobin concentration (Hb) in mothers was 10.90-14.45 g/dl (PCV, 32.42-43.92%). Hb in cord blood was 12.50-17.68 g/dl (PCV, 37.5-52.90%). Average total white blood cell count (WBC) in mothers was 3.32-10.70 X 109/l and in cord blood, 4.10-13.10X109/l. Haemoglobin genotype revealed that AS was higher in maternal blood (17.5% vs 4.8%) while AA was higher in cord blood (94.2% vs 82.5%). Conclusion: The study adds to the data base of reference haematological values in Nigeria, especially the South-South zone and suggests that the frequency of the AS genotype may be undergoing a gradual reduction in subsequent generations as malaria is being controlled makings its relative advantage less important. Testing of prospective couples and counselling of AS individuals is still very important.
