Aids in the diagnosis of coccidioidomycosis. Includes screening by immunoassay (IgM and IgG) and confirmation by complement fixation and immunodiffusion. For comprehensive nonreflex testing, refer to Coccidioides Antibodies Panel, Serum (0050588).
Complement Fixation/Immunodiffusion/Enzyme-Linked Immunosorbent Assay (ELISA)
New York DOH Approval Status
Serum Separator Tube (SST).
Separate from cells ASAP or within 2 hours of collection. Transfer 2 mL serum to an ARUP Standard Transport Tube. (Min: 0.6 mL). Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens.
Other body fluids. Contaminated, hemolyzed, icteric, or lipemic specimens.
Mark specimens plainly as "acute" or "convalescent".
Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
|Coccidioides Antibody, IgM by ELISA||0.9 IV or less|
|Coccidioides Antibody, IgG by ELISA||0.9 IV or less|
|Coccidioides Antibodies, IgG by Immunoassay, Serum||0.9 IV or less Negative - No significant level of Coccidioides IgG antibody detected.
1.0-1.4 IV Equivocal - Questionable presence of Coccidioides IgG antibody detected. Repeat testing in 10-14 days may be helpful.
1.5 IV or greater Positive - Presence of IgG antibody to Coccidioides detected, suggestive of current or past infection.
|Coccidioides Antibodies, IgM by Immunoassay, Serum||0.9 IV or less Negative - No significant level of Coccidioides IgM antibody detected.
1.0-1.4 IV Equivocal - Questionable presence of Coccidioides IgM antibody detected. Repeat testing in 10-14 days may be helpful.
1.5 IV or greater Positive - Presence of IgM antibody to Coccidioides detected, suggestive of current or recent infection.
Coccidioides Antibodies, IgM and IgG by Immunoassay, Serum is used to screen for coccidioidal antibodies. If the immunoassay testing is equivocal or positive for IgM and/or IgG, then Coccidioides Antibodies by Immunodiffusion and Coccidioides Antibody Titer by Complement Fixation, Serum will be added. Additional charges apply.
