Abstract

Objective: To evaluate the values of some major hematological parameters at different trimesters of pregnancy. Methods: The research involved 33 healthy pregnant women as the study group and 11 non-pregnant women as control. The age range of these women was 20-40 years. Ethical approval was obtained from Olabisi Onabanjo University Teaching Hospital, Sagamu. Three milliliters of venous blood collected from the median cubital vein with minimum stasis were put into K+EDTA bottle. The blood was properly mixed and analyzed for packed cell volume (PCV), total white cell count, differential counts and erythrocyte sedimentation rate (ESR). Hematology was done according to standard methods. Results: The result showed that study group exhibited statistically significant lower values of PCV, monocyte and lymphocyte while WBC, eosinophil and ESR were not significantly changed. There was no significant difference in all hematological parameters among the three trimesters. Conclusions: Healthy pregnancy may have effect on hematological parameters. Therefore, there is a need to monitor these parameters during pregnancy. We also find that stages of pregnancy have no influence on hematological parameters.
