Both the renal and liver function tests of your father are abnormal. Does you father have history of taking alcohol ? Is he on any medications ? He is a diabetic ?
These tests would require further evaluation. I would suggest the following investigations
For the liver :
2. viral markers- hepatitis B
For the kidney
1. urinary albumin/creatinine
2. urine examination for casts in urine
If he is taking alcohol, i would advise to stop that. Please send the reports and I would be glad to review them.
