 False positives may occur because of fungal contaminants in the antibiotics amoxicillin-clavulanate, and piperacillin/tazobactam.False positives can also occur with contamination of clinical specimens with the bacteria "Streptococcus pneumoniae", "Pseudomonas aeruginosa", and "Alcaligenes faecalis", which also produce (1→3)β-D-glucan.This test can aid in the detection of "Aspergillus", "Candida", and "Pneumocystis jirovecii".
