This study intended to design a device that can accurately classify and identify the blood type and RH of a person. Aside from its reading apparatus, the system could also display and save the results fast in a computer.
To establish the functionality of the device, experimental development and descriptive approaches were applied. Ten purposively chosen evaluators consisting of students from different schools in Davao City participated in the study.
The findings showed that the digitized blood type identifier was successful in generating identical results with those which were determined using the manual procedure. Thus, the device was established as a reliable medical instrument in terms of its functionality and accuracy.
