LEVELS OF HAEMOGLOBIN AND PACKED CELL VOLUMES IN UMBILICAL CORD BLOOD IN JOS

Haemoglobin and packed cell volume have been studied in many neonatal study populations, but in Jos, Nigeria, no real reference values exist. On the other hand, disorders of the blood are common in this environment, necessitating knowledge of the references values of blood parameters as are applicable to neonates. Blood samples were taken from 121 umbilical cords at time of birth, and were analysed for haemoglobin concentration (Hb) and packed cell volume (PCV). The Hb concentration was determined by the indirect colorimetric method, and the PCV by the microhaematocrit centrifuge method. The mean values obtained were Hb 12.13 ± 0.11 g/dl and PCV 37.95 ± 0.49%. The mean umbilical cord blood haemoglobin and packed cell volumes were compared with those of the mothers, taken also at the time of delivery. The maternal values were Hb 10.87 ± 0.012 g/dl and PCV 34.51 ± 0.045%. The comparison shows statistically significant difference in Hb (P<0.0001, n =121) and PCV (P<0.0001, n = 121). The study establishes a baseline data on Hb and PCV in neonates in Jos.
