Hi All, My father drinks from a long time around 16-17years. Now he drinks more like 4-5 peg everyday. Whenever we get his liver test done - the test usually comprises of SGOT, SGPT and Bilirubin. These some times comes elevated and sometimes normal. When I researched I realised that liver failure is hard to diagnose until it is 80% failed. I want to know which is the best liver diagnosis test from which we can identify early symptoms of liver failure. Kindly reply back as soon a possible.
