name
descriptionImmunodiffusion (ID) and complement fixation (CF) are used to detect antibodies to Histoplasma capsulatum in spinal fluid. The ID assay detects the presence of antibodies to the H. capsulatum M and H precipitin bands. The M band is present during acute infection, but can also be present during chronic infection and be detectable for months or years after the infection has resolved. The H band is present during chronic or severe acute infections. The M band is usually also present when the H band is detected. [PMID: 17223625]
