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.
