Biochemical analysis including standard liver and renal function tests, as performed daily until death or recovery.

Liver function tests and renal function tests are often abnormal.

Liver function tests, renal function tests and electrolytes should be monitored while on therapy.

Renal function tests; blood, urea, nitrogen (BUN); and creatinine.

Laboratory investigations may include serum and urine calcium and phosphate, and possibly liver and renal function tests.

Laboratory tests that might show abnormalities include blood count tests, renal function tests, electrolyte tests, and liver enzyme tests.

Renal function test: A procedure in which blood or urine samples are checked to measure the amounts of certain substances released into the blood or urine by the kidneys.

Investigations to assess involvement of other organs frequently involve electrocardiogram, ocular examination by an ophthalmologist, liver function tests, renal function tests, serum calcium, and 24-hour urine calcium.

Investigations: CBC, Renal function test (RFT), Liver function test (LFT), coagulation screen, plasma rate concentration, 24 hour urine analysis, ultrasound.

Relevant preoperative clinical details were recorded as well as routine laboratory investigations (full blood count, hepatic and renal function tests) and radiological assessments (chest radiographs, abdominal computed tomography, and ultrasound scans).

Hepatic and renal function tests should be performed; patients with irreversibly elevated serum bilirubin are excluded, and iodinated contrast use should be avoided or minimized in patients with renal insufficiency.

When the cause is not obvious, clinicians use other tests: ESR, ferritin, serum iron, transferrin, RBC folate level, serum vitamin B, hemoglobin electrophoresis, renal function tests (e.g. serum creatinine).
