Histoplasma Antibodies by Complement Fixation
Also known as: HISTO
Use
Histoplasma Antibodies by Complement Fixation aids in the diagnosis of histoplasmosis. It is not recommended as a standalone test. For more complete serologic testing, immunodiffusion should be performed in parallel with complement fixation. A titer of 1:8 or greater is generally considered presumptive evidence of histoplasmosis. A titer of 1:32 or greater or rising titers indicate strong presumptive evidence of histoplasmosis. Cross-reactions, usually at lower titers, may occur with other fungal diseases.
Special Instructions
Not provided.
Limitations
This test detects total antibodies to mycelial and yeast antigens of Histoplasma and is prone to cross-reactions with other fungal diseases at lower titers.
