The evaluation of liver function via grey relational analysis

Liver diseases and liver cancer has been the top ten causes of death among ten leading causes of death in Taiwan and always in the top. Usually, in the general liver function examination, biochemical test is the most common and a test that show the most direct reflection of the body condition. The health subject can determine the further inspection according to the inspection results. Nevertheless, the result of biochemical tests is not absolute, nor is the results represent in the normal range will not be suffering from liver disease. Therefore, how to let the health subject understand his/her own health condition is the main purpose of this paper. So, this paper makes use of grey relational analysis method and according to the standard values of hospital test results to be divided into Level method and compare with the health subject´s test results. It will convert the past ordinal decision into cardinal quantitative evaluation value and evaluate liver function´s level. At the same time, it develops MATLAB GUI toolbox to assist the numerical calculation, which can complete a medical assistance platform for liver function evaluation. It not only provides a further step of making decision for doctors in order to promote medical quality, but also provides a new research direction of this field.
