Going by the acute pain abdomen and deranged Liver Function Tests, I suggest you get a couple of investigations done at the earliest:
2. blood tests: Viral markers of hepatitis, serum lipase
, complete blood count
, serum creatinine
3. blood culture
4. routine urine examination
In case you are having fever what evidence based medicine says is that in case you do a blood culture ,it is far superior that getting widal tests and other such tests.
After getting the reports can we arrive at a definite diagnosis.
At present probably it is a case of acute hepatitis
? viral hepatitis
