beta d glucan testing

β-d-glucan assays can detect the presence of several different fungi, including Aspergillus, Candida, and Pneumocystis jirovecii. Unfortunately, cross-reactivity also extends to β-lactam antibiotics (eg, piperacillin) and immunoglobulins, which raises the concern for false-positive test results.1

Cross reacts except for Mucor and cryptococcus.2
