Interpretive Data
The Fungitell test is indicated for presumptive diagnosis of fungal infection and should be used in conjunction with other diagnostic procedures. This test does not detect certain fungal species such as Cryptococcus, which produce very low levels of (1,3)-beta-D-glucan. This test will not detect the zygomycetes, such as Absidia, Mucor, and Rhizopus, which are not known to produce (1,3)-beta-D-glucan. In addition, the yeast phase of Blastomyces dermatitidis produces little (1,3)-beta-D-glucan and may not be detected by the assay.
