Test Overview

Test Methodology

Routine testing is performed by the complement fixation method. Immunodiffusion methodology will be used to resolve questions of cross-reactivity, if the specimen has anti-complementary antibodies or if specifically requested in suspected cases of blastomycosis.

Test Usage

To obtain serologic evidence of an immune response (antibody production) to Histoplasma capsulatum, Blastomyces dermatitidis, or Coccidioides immitis.

Reference Range*

Negative. A four-fold or greater rise in titer between acute and convalescent paired specimens, collected 14-21 days apart is consistent with the diagnosis of recent infection. In the presence of high titer against one fungal pathogen, other low level antibody titers may represent a cross-reaction and are not considered significant.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
