Cord blood full blood count parameters in Lagos, Nigeria

Full blood count (FBC), one of the most frequently requested for laboratory investigations, is a simple, fast and cheap test and is a reliable indicator of health. Due to its usefulness in the assessment of health status of individuals, its parameters in cord blood, a major source of haemopoietic stem cell transplantation and an ideal source for laboratory investigations for newborns were determined to provide a useful guide to local neonatologists and stem cell transplant physicians.

Three millilitres of umbilical cord blood was collected from 130 normal birth weight newborns (69 males and 61 females) whose cord were clamped immediately after delivery, at a teaching hospital in Lagos, Nigeria and full blood count parameters were determined using Sysmex autoanalyzer, model KX-21N. Consented mothers of the newborns were selected based on, age between 18 and 45 years; uneventful pregnancy and delivery and haemoglobin (Hb) concentration ≥ 10 g/dL.

There were no statistical gender differences in the mean values of Hb concentrations (M = 13.27 ±1.60 g/dL; F = 13.32±1.61g/dL; p = 0.93), total white cell count (M = 3.16±5.43 × 10(9)/L; F = 13.07±4.98 × 10(9)/L; p= 0.92), platelet count (M= 223.64± 64.21 × 10(9)/L; F = 226.69±80.83 × 10(9)/L; p = 0.81) and other parameters.

Mean values of full blood count parameters obtained in this study are comparable to reports from other studies in developing countries and could be a useful guide for neonatologists and stem cell transplant physicians in our geographical location.
