Non-invasive Approach for Blood group Detection

The determination of an existent’s blood group is essential during transfusions and transplants. The previously developed system involves drawing blood samples and conducting an antigen- antibody response, which is time consuming and requires chemical reagents. In this study, we propose a non-invasive system for relating blood groups using light as a source of optic signals passed through the cutlet, which is also detected by an optic sensor. As the optic parcels of blood vary for different antigens present on the RBC, the voltage attained also varies. Depending on the affair voltage of the sensor, blood groups can be determined without puncturing the skin, making it an accessible and uncomplicated process.
