Abstract
In this study, the subpopulations of human blood parameters which consist of white blood cells, red blood cells, platelets, and its components were determined by electronic sizing in the Sejahtera Centre of Universiti Sains Malaysia. These parameters have been correlated with human characteristics such as age, gender, ethnicity, blood groups, body mass index, and various medical histories, before and after irradiation with 632.8 nm He-Ne laser at energy density of 1.7 x 10-17 J/cm2, and with 10,600 nm CO2 laser at energy density of 1.9 x 10-19 J/cm2. Correlations were obtained by finding patterns in changes of blood parameters using paired and independent tests and the relationships were identified by using regression analysis. The statistical analyses were performed using SPSS version 17. The objectives of this research are to compare between He-Ne and CO2 laser irradiation on human blood parameters, to study the correlations between blood parameters with human characteristics before and after irradiation and to study blood–laser beam interaction via 2D contour and 3D profile images. Irradiation of blood samples with He-Ne and CO2 lasers respectively, showed significant changes in white blood cells, red blood cells, platelets, and its components. The difference in changes in human blood parameters of a patient’s characteristics depend on the type of laser used. The relationship between a change in human blood parameters and a patient’s characteristics conducted using a logistic regression analysis found that by using He-Ne laser an increase in mean white blood cells is significantly related with age, gender, and blood group O. An increase in mean red blood cells is significantly related with blood group B, blood group AB, and body mass index, and a decrease in mean platelet is significantly related for respondents with blood group AB having one chronic disease.
