Overview
An elevated/reduced concentration of serum/blood/urinary/CSF/other [lab test] is diagnostic of [disease name].
OR
Laboratory findings consistent with the diagnosis of [disease name] include [abnormal test 1], [abnormal test 2], and [abnormal test 3].
OR
[Test] is usually normal among patients with [disease name].
OR
Some patients with [disease name] may have elevated/reduced concentration of [test], which is usually suggestive of [progression/complication].
OR
There are no diagnostic laboratory findings associated with [disease name].
Laboratory Findings
- There are no diagnostic laboratory findings associated with [disease name].
OR
- An elevated/reduced concentration of serum/blood/urinary/CSF/other [lab test] is diagnostic of [disease name].
- [Test] is usually normal among patients with [disease name].
- Laboratory findings consistent with the diagnosis of [disease name] include:
- [Abnormal test 1]
- [Abnormal test 2]
- [Abnormal test 3]
- Some patients with [disease name] may have elevated/reduced concentration of [test], which is usually suggestive of [progression/complication].
Laboratory Findings
Ammonia levels
An ammonia level more than 200 strongly suggests hepatic encephalopathy.[1]
Ammonia levels over 123 are likely to improve with lactulose therapy.[2]
Other tests may include:
- Anemia is a predictor of hepatic encepphalopathy in some patients with hepatic cirrhosis.[5]
- Liver function tests: patients may have abnormal bilirubin, albumin, AST, ALT, AST/ALT, INR due to hepatic disease.[6]
- BUN and creatinine to see how the kidneys are working
- Hypercreatinemia may be present in patients with end-stage liver disease
