Aspergillus Antibody by CF : 0050100

Mnemonic: ASPER

Methodology: Complement Fixation
Performed: Sun-Fri
Reported: 2-4 days
Specimen Required: Collect:  One 4 mL serum separator tube.

Storage/Transport Temperature:  1 mL serum at 2-8°C. (Min: 0.15 mL)  Submit specimen in an ARUP Standard Transport Tube.

Remarks:  Separate serum from cells ASAP. Acute and convalescent specimens must be labeled as such; parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Please mark specimens plainly as "acute" or "convalescent."

Unacceptable Conditions:  Severely lipemic or contaminated specimens.

Stability (collection to initiation of testing):  After separation from cells: Ambient: 2 days; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
Reference Interval:
< 1:8
Interpretive Data: Cross-reactions with dimorphic fungi are not unusual with the genus Aspergillus. A negative test does not exclude infection, especially in immunocompromised patients. Best use of the test is with paired sera taken three weeks apart to detect a rise in titer against a single antigen.
Note: Negative fungal serology does not rule out the possibility of current infection.
CPT Code(s): 86606
