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 for 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
Blood work
- CBC with differential
- Leukocytosis with marked eosinophilia is present(>10% eosinophils/µL)[1][2]
- Anaemia
- Elevated BUN
- Elevated serum creatinine
- Raised ESR
- Elevated c-reactive protein
- Elevated troponin T[3]
Urine analysis
- Proteinuria
- Microscopic hematuria
- Red cell casts
- Albuminuria
- Abnormal sedimentation
Immunologic tests
- Antineutrophil cytoplasmic antibodies[4][5]
- P-ANCA positive in most cases
- Elevated levels of IgE[6]
- Elevated levels of rheumatoid factor at low titer
- Hypergammaglobulinemia
- C3, C4 levels may be normal or elevated
- Increased levels of eosinophil cationic protein[7]
