A total 302 healthy volunteers whose ages ranged between 20â€“45 years, were investigated. All laboratory analysis was conducted under standardized conditions at the Haematology Section, Department of Pathology, Bakhtawar Amin Memorial Trust, Hospital (BAMTH) and Multan Institute of Cardiology, (MIC). <strong>Results: </strong>In Males, the mean Haemoglobin concentration (Hb) of 13.04 g/dl and Haematocrit (HCT) ratio of 0.39 l/l were significantly higher than females value of 11.63 g/dl and 0.35 l/l respectively. The mean Red Blood Cell (RBC) count of 5.3Â´10<sup>12</sup>/l in males was also significantly higher than the corresponding value of 4Â´10<sup>12</sup>/l in females (<em>p</em>&lt;0.05). The value of Mean Corpuscular Volume (MCV) in males (76.30 fl) was significantly higher than in females (73.84 fl), (<em>p</em>&lt;0.05). Similarly the Mean Corpuscular Haemoglobin (MCH) and Mean Corpuscular Haemoglobin Concentration (MCHC) were significantly higher in males than corresponding values in females (<em>p</em>&lt;0.05). On the other hand, the mean White Blood Cell count (WBC) of 8.25Â´10<sup>9</sup>/l in males was lower than mean value of 8.42Â´10<sup>9</sup>/l in females (<em>p</em>&lt;0.05). Similarly the values for Platelet count of 255Â´10<sup>9</sup>/l in males were also significantly lower than corresponding values of 255Â´10<sup>9</sup>/l in females (<em>p</em>&lt;0.05). <strong>Conclusions: </strong>This study has established baseline values for haematological parameters in healthy Pakistani adults of Multan and surrounding areas. The sex difference of measured levels of all of these parameters has attained statistical significance. When the observed values of this study were compared with those quoted for the methods in use and those drawn from different populations, significant differences were revealed. Such differences are of accurate clinical interpretation of haematological investigation of patients.</p>}, number={1}, journal={Pakistan Journal of Physiology}, author={Usman, Khalid and Syed, Zeeshan Ali and Rao, Arif Ashfaq}, year={2007}, month={Jun.}, pages={19–22} }
