Test ID: FSS    
Fungal Antibody Survey, Serum

Useful For Suggests clinical disorders or settings where the test may be helpful

Screening for antibodies to dimorphic fungi (Blastomyces, Coccidioides, Histoplasma) and the antigen of Cryptococcus neoformans during infection

Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

See individual test IDs.

Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

Blastomyces ANTIBODY BY EIA

Negative

 

Coccidioides ANTIBODY

Complement fixation: negative

If positive, results are titered.

Immunodiffusion: negative

Results are reported as positive, negative, or equivocal.

 

Cryptococcus ANTIGEN SCREEN

Negative

If reactive, results are titered under the reflex test.

 

Histoplasma ANTIBODY SCREEN

Negative

Interpretation Provides information to assist in interpretation of the test results

See individual test IDs.

Cautions Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

Cross-reacting antibodies may be produced and sometimes present interpretive problems.

Clinical Reference Provides recommendations for further in-depth reading of a clinical nature
