Abstract

This study assessed some haematological parameters of bankers in Calabar metropolis. A total of 100 people (male
and female) between the age of 21 and 60 were recruited for this research, 50 bankers and 50 non-bankers who served
as control. 4mls of blood was collected by venipuncture into an EDTA bottle for full blood count and erythrocyte
sedimentation rate. Using Microhaematocrit method for packed cell volume (PCV), visual manual method for total
white cell count and platelet count, cyanmethaemoglobin method for haemoglobin estimation and, Westergren’s
method for erythrocyte sedimentation rate (ESR). Results were expressed as means ± standard deviation, while
student’s t-test and analysis of variance was used for comparison of means; P was statistically significant at <0.05.Of
all the haematological parameters analyzed, there was a significant increase in basophil and a decrease in PCV and
platelet count (0.06 ± 0.31× 1012, 0.42 ± 0.05 l/l, 283.32 ± 78.20× 109) in bankers when compared with the control
(0.30 ± 0.65× 1012, 0.35 ± 0.41 l/l, 253.48 ± 71.18× 109) respectively. It also shows that there was a significant
reduction in the PCV and the haemoglobin concentration mean ± standard deviation of female bankers
(130.72±20.87, 0.40 ± 0.04 l/l) compared to their male counterparts (156.50±26.07, 0.48 ± 0.05 l/l). This study also
reveals that based on the duration of service, ESR was (14.44 ± 8.40 mm/hr.) amongst those who have been working
for 6 – 10 years, while those who have worked for less than 6years had an ESR of (9.23 ± 7.31). Pearson’s correlation
showed a strong positive association between PCV and haemoglobin concentration that was significant.
