Evaluation of the sensitivity and the specificity of the Aspergillus antigen-capture ELISA for the detection of culture filtrates of fungal antigens. Culture filtrates from five Aspergillus species gave a very strong positive signal following the dilution (approximately 1:10,000) of cell cultures containing 2 × 106 cells/ml. The culture filtrate from Penicillium marneffei was not detectable beyond a dilution of 1:2.
