| Additional information | This assay does not detect certain fungal species such as Cryptococcus (Tanaka et al, 1991) or the yeast phase of Blastomyces (Girouard et al 2007) that produce very low levels of Beta-D-Glucan, The assay also does not detect fungal spercies that do not produce Beta-D-Glucan such as Absidia, Mucor and Rhizopus (Mitsuya et asl 1994). Due to the potential for contamination by oral Candida Sp. this test is inappropriate for sputum, BAL or other respiratory samples colelcted through the mouth. |
