Blood Type Identification Through Spectrophotometry and Optical Density Analysis

Blood is a vital component in body system regulation and sustaining homeostasis. It is responsible for transporting oxygen and nutrients, as well as maintaining body pH and temperature. Blood type. Blood typing is essential in the medical fields and hematology. It makes processes like blood transfusion and donation to be faster and safer. Slide method is a known traditional method for blood typing and new biomedical techniques in image processing. Though proven to be effective, the traditional way takes time to process and is prone to human errors. Image processing on the other hand is functional yet expensive to assemble and operate. The study developed an alternative device to determine the blood type via spectrophotometry and optical density characterization and analysis. The proposed electronic device collects and analyzes data from the reaction of the blood samples subject to a specified wavelength. The prototype can display the corresponding blood type that ranges from A+, B+, AB+, O+, A-, B-, ABand Oin a short time. A total of 39 blood samples used in calibration and actual testing collected from the National Blood Services laboratory of the Philippine Red Cross exhibit promising results.
