Fast and accurate identification of blood types is very important during emergency situations before administering a blood transfusion. At present the blood culture is done using automated blood analyser. When blood is drawn for blood test it may cause bleeding under the skin, fainting, and infections at the particular region. The proposed idea is a non-invasive method for the identification of blood group of a patient without pricking the skin of the patient. This method is used to automatically determine human blood type by applying image processing algorithms to the optically captured images of superficial capillaries underlying the skin surface. The technique embeds Light scattering method, as light passes through the capillaries for dynamically classifying blood cells based on specific antigen shapes present on the Red Blood Cell (RBC) surface such as A antigen, B antigen and AB antigen. Optically sensitive web camera is used to capture the scattered light pattern, from the red blood cells to determine the blood type without drawing the blood samples from the body of patient. The process is simple and convenient to determine ABO blood group instantly, so it can be economically used for undertaking blood tests in hospitalized conditions, emergencies, war fields and it is more comfortable for infants.
