Liver function tests are routinely investigated for suspected liver disorders due to infection by blood
borne viruses such as HCV, HbsAg which leads to a host of liver disorders. A total of 7 tests are
collectively done to evaluate the role and normal functioning of synthetic, metabolic and excretory
functions of liver. Each test has its specific diagnostic use to assess the above three standard functions of
liver. While individual tests are specific to one particular function and as the exact malfunction of the
liver is not known, all the tests are done together, and a statistically significant association should exist
between any two liver function tests whether the patients liver functions are normal or abnormal.The
outcome of this study has established that there is always statistically significant association between any
two liver function tests suggesting the need to order all the liver function tests collectively or specific tests
depending upon clinical diagnosis as pointed out in many studies mentioned under literature review.
