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.

FISH - Fluorescent In-situ Hybridization

Fluorescence in situ hybridization, or FISH, was developed in the early 1980s and has quickly become one of the most widely used techniques in cytogenetics. Labeled probes are used to bind complementary DNA or RNA sequences on a chromosome or in a region within a cell. Earlier, the probes could only be obtained by cloning or reverse transcription of a DNA template. Currently, the probe oligonucleotides can be synthesized synthetically. Additionally, with the advancement of optical techniques,...

Labeling DNA Probes

DNA probes are fragments of DNA labeled with a reporter tag to enable their detection or purification. The resulting labeled DNA probes can then hybridize to target nucleic acid sequences through complementary base-pairing, and may be used to recover or identify these regions.
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...

Fluorescence and Phosphorescence: Instrumentation

Fluorometers and spectrofluorometers are two types of instruments used for measuring molecular fluorescence. These instruments differ in how they select excitation and emission wavelengths and the type of light sources they utilize. Fluorometers use absorption interference filters to choose excitation and emission wavelengths. The excitation source in a fluorometer is typically a low-pressure mercury vapor lamp that emits intense lines distributed throughout the ultraviolet and visible regions.
