In the ID assay, antibodies against Histoplasma H and M antigens precipitate on an agar gel. The H band is seen in < 20% of cases, is rarely seen without the M band, and confirms acute infection. The M band is much more common and often persists after the infection has resolved [1, 47]. WebbHistoplasmosis comes from breathing fungal spores found in bat and bird droppings. Mild infections produce no signs. Severe forms can be fatal. Learn more.
SHSTO - Overview: Histoplasma Antibody, Serum
WebbCross-reactivity in Histoplasma serologic tests was evaluated by using sera from patients with histoplasmosis and other infections. Serum samples from 127 of 134 (95%) patients with histoplasmosis were judged positive by complement fixation tests, and 121 (90%) showed H bands, M bands, or both by immunodiffusion. Webbantigen coccidioidin, only one patient (histoplasmosis case number 5) responded positively-with a titer of 1:8. scribed by Heiner in 1958. He designated as the "M" band a band that was the result of a reaction between the histoplasmin antigen and the antibody produced in response to skin test-ing. A band that resulted from reaction with saber rocky mount

Reactive results will indicate presence of M or H bands (precipitins), or both M and H bands.
