Hi.. one of my friends is in the ICU, the doctors have not been able to diagnose the cause and they have put him on dialysis. His blood tests are normal parameters for all the checks, but his creatinine has been increasing, it was around 8 to start with and he has been under treatment in numerous hospitals for over the past one month, but it started to increase to 14 around 3 days back and today it is around 18. Could anyone pls let us know what could be the diagnosis....
