Disclosed herein are methods of detecting microbial infection in mammalian subjects comprising treatment of a sample and detection of polysaccharide antigenic components. The methods disclosed provide for pretreatment of biological samples, such as urine samples, to maximize detection of galF—containing antigens and improvement of sensitivity of galF antigen detection assays. The methods include minimizing Intelectin-1 binding to galF—containing antigens and improvement of monoclonal antibody binding. The detection methods are useful for identifying the presence of microbial antigens related to Streptococcus pneumoniae, Klebsiella pneumonia, Escherichia coli, Mycobacteria species, Malassezia species, Aspergillus species, Fusarium species, Alternaria species, Coccidioides species, Cryptococcus species, Mucormycetes, Histoplasma species, Neosartorya species, Fusarium species, Paracoccidioides species, or combinations thereof. |
