Laboratory

Sent to Mayo Medical Laboratories, Rochester, MN.

Performed

Monday, Wednesday, Friday.
Results available in 2-5 days.

Reference Range

Negative.

Test Methodology

Latex Agglutination.

Interpretation

Any titer should be considered clinically significant, however, clinical correlation must be present.

Some cutaneous infections are associated with negative serologic results.

Extracutaneous infections, including disseminated and articular infections, produce positive tests.

Clinical Utility

This assay aids in detecting antibodies in extracutaneous sporotrichosis. Sporptrichosis usually is a subcutaneous mycosis caused by Sporothrix schenckii. The fungus typically is introduced by minor trauma into subcutaneous tissue and produces a mycotic infection. The infection may be limited to the site of inoculation or may spread along proximal lymphatic channels.

CPT Code
