Histoplasma Antibodies by Complement Fixation and Immunodiffusion
Also known as: HISTO PAN
Use
This test aids in the diagnosis of histoplasmosis, a fungal infection caused by Histoplasma capsulatum. Detection of antibodies through complement fixation and immunodiffusion helps in confirming infection. It is recommended to be used in conjunction with Histoplasma Antigen Quantitative by EIA for a comprehensive diagnosis.
Special Instructions
Not provided.
Limitations
A titer of 1:8 or greater may suggest histoplasmosis, but cross-reactions can occur with other fungal diseases, typically at lower titers. This test does not exclude the possibility of an infection even if antibodies are not detected.
