Routine blood tests are usually the next step in diagnosis after a thorough medical history and physical examination. They should include a full blood count, blood urea nitrogen (BUN), creatinine, and liver function tests such as albumin, international normalized ratio (INR), partial thromboplastin time (PTT), serum amylase and total bilirubin (TBIL). If late-stage liver disease is suspected, then a serum glucose may be appropriate.
