New diagnostic tools have been developed for the diagnosis of this mycosis that allow the identification of the main species, from improvements in conventional stains such as calcofluor white, which increases sensitivity, as well as technologies such as T2 Candida, MoiM assay, biomarker panel (1,3 β-D-glucan, C-reactive protein, presepsin, and procalcitonin), and, more recently, the development of biosensors for the identification of Candida spp. Here, CRP is linked to fungal infectious disease.
