Enzyme-Linked Immunoassay Dot (Immunodot)
Negative
Aid in the diagnosis of leptospirosis.
The temporal IgM immune response can vary among patients. Therefore, a single negative result by this assay should not be used to exclude diagnosis, especially in patients with symptoms suggestive of leptospirosis who have an appropriate exposure history. This test does not distinguish between acute or past infection. Clinical correlation is required. Patients may remain seropositive for months to possibly years following resolution of disease; therefore, this test cannot be used to establish cure or response to therapy.
Test is sent to Mayo Clinic Laboratories.
