This paper presents an innovative prototype to perform
pre-transfusion tests especially developed for emergency
situations. This prototype is portable and automates the
procedure of the plate test. The prototype is based on image
processing techniques to analyze the captured images from the
performed test. The image processing techniques are able to
detect agglutination reactions in the samples and based on the
results of occurrence or absence of agglutination the result of the
test is given. This paper also presents a user-friendly interface
application to be used with the prototype developed. In this study
the tests were performed with the prototype for ABO and Rh
blood types and the prototype was tested with donor blood
samples
