Not recommended. For initial establishment of diagnosis, refer to Coccidioides Antibodies Reflexive Panel (3001982).
Serum Separator Tube (SST).
Transfer 0.5 mL serum to an ARUP Standard Transport Tube (Min: 0.3 mL)
Contaminated, hemolyzed, or severely lipemic specimens.
Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
Coccidioides infection is demonstrated by the detection of IgM antibody to the Immunodiffusion Tube Precipitin (IDTP) antigen. IgM antibody may be detected 1 to 3 weeks after the onset of primary infection and may suggest active or recent infection. IgM antibody is rarely detected 6 months after infection but may reappear with relapse and may persist in disseminated cases. IgG antibody may also be demonstrated in response to the Immunodiffusion Complement Fixation (IDCF) antigen and may represent active or past infection. Negative fungal serology does not rule out current infection.
No compliance statements are in use for this test.
This test uses culture filtrates of Coccidioides immitis and includes IDCF and IDTP antigens.
