Complement Fixation Test Reagents

The complement fixation test remains the ‘Gold Standard’ in the serodiagnosis of many diseases.

The complement fixation reagents listed here are used to test patients’ sera for complement fixing antibodies against Histoplasma capsulatum, Blastomyces dermatitidis, Coccidioides immitis, and Aspergillus fumigatus.

The antigens include both optimally diluted (i.e. ready-for-use) and concentrated (i.e. must be diluted to optimum).
