Abstract
A medical analysis system for reading and interpreting an occult blood test (OBT) device is provided. The instant system comprises an image sensor for capturing an image of the entire test area of the fecal occult blood test (FOBT) device and for converting the image into a digital data. The system further comprises a data processor conventionally coupled to the image sensor. The data processor compares the digital data with pre-determined threshold conditions of a positive FOBT by utilizing a spectrographic and morphologic image analysis algorithm and determines a presence of the occult blood in the sample. A hue angle analysis for data processing may be used. A method of performing FOBT on a sample is also provided.
