HISTOPLASMA ANTIBODIES

LAB795

Collect

Serum separator tube.

Specimen Preparation

Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.25 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of acute specimens. Mark specimens plainly as acute or convalescent.

Unacceptable Conditions

Storage/Transport Temperature

Refrigerated.

Stability (from collection to initiation)

After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)

Notes

Negative fungal serology does not rule out the possibility of current infection.

Synonyms

Ordering Recommendations

Not recommended as a stand-alone test. Refer to Histoplasma Antibodies by CF & ID (0050627).

Reference Interval

Components
Reference Interval
Histoplasma Mycelia, CFLess than 1:8
Histoplasma Yeast, CFLess than 1:8

Interpretive Data

An antibody titer greater than or equal to 1:8  is generally considered presumptive evidence of histoplasmosis. Greater than 1:32 or rising titers indicate strong presumptive evidence of histoplasmosis.

Yeast phase is regarded as more sensitive. Approximately 90-95 percent of cases have positive titers to one or both antigens. Titers to mycelial antigen are higher in chronic infection. Cross-reactions, usually at lower titers, may occur with other fungal disease. Rising titers suggest progression of infection. Skin tests in individuals previously exposed may cause titer elevation in 17-20 percent of cases.
