Abstract

Hemophilia (HP), the deficiency of clotting factors such as VIII (FVIII) and IX, is an inherited blood disorder which is due to the lack of clotting protein. Conventional techniques for detecting hemophilia are based on clotting factor tests such as hemostasis assays to determine various types of hemophilia and its severity. In the current study, we propose a new approach involving a spectral technique to discriminate normal controls from hemophilia patients with an accuracy above 80 %. This accuracy is calculated on the normalized relative intensity based on the light measurement of blood components by analyzing a certain set of fluorescent bio molecules. Our results indicated that Red Blood Cells (RBCs) show lower porphyrin content and enzyme deficiencies in hemophilia patients than in normal controls. Therefore, the spectral features in hemophilia patients are different from those of normal controls. Thus, the proposed technique is a good alternative for the detection of hemophilia patients when compared with conventional detection techniques.
