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
- Laboratory findings consistent with the diagnosis of insulinoma include
- S. glucose <50 mg/dL
- S. Insulin >5-10 μU/mL
- S. C-Peptide >200 pmol/L
- S. proinsulin ≥ 22 pmol/L
- Patients with insulinoma may have elevated insulin to glucose ratio >0.4, which is usually suggestive of insulinoma after a 72-hour fast test.It is a gold standard test.
- 1/3rd or 33% patients have clinical symptoms with in 12 hour of the fasting.
- 80% develop within 24 hours
- 90% develop within 48 hours
- 100% develop within 72 hours
