Overview
There are no diagnostic lab findings associated with uveitis. The presence of certain non-specific laboratory findings, in the presence of uveitis, may be suggestive of certain underlying causes.
Laboratory findings
There are no diagnostic lab findings associated with uveitis. The presence of certain non-specific laboratory findings, in the presence of uveitis, may be suggestive of certain underlying causes such as:
Complete blood count
- A low hemoglobin or hematocrit with microcytosis or marginal normocytosis may be indicative of blood loss by inflammatory bowel disease, or any chronic inflammatory disorder.
White blood cells and differentials
- Elevated white blood cells with a left shift may be suggestive of an underlying infection.
- Decreased white blood cell count may be indicative of an immunosuppressed state.
ESR and CRP
- Elevated ESR and CRP may be suggestive of an underlying infection or inflammatory condition.
Iron studies
- Low ferritin with a high TIBC is suggestive of chronic blood loss by inflammatory bowel disease.
- High ferritin may be suggestive of anemia of chronic inflammatory conditions.
Serology tests
- HLA subtyping: HLA-B27, HLA-A29, HLA-B9, HLA-B15
- Antinuclear antibody (ANA)
- Venereal disease research laboratory (VDRL) or Rapid Plasma Reagin (RPR) for syphilis
- Purified protein derivative (PPD) for tuberculosis
- Lyme titer
- HIV test
