Chang, Euijin, et al. “Limited Positive Predictive Value of β-d-Glucan in Hematologic Patients Receiving Antimold Prophylaxis.” Open Forum Infectious Diseases, vol. 7, no. 3, 2020, pp. ofaa048.

Retrospective study from South Korea evaluating the predictive value of BD glucan in the age of mold active triazole prophylaxis. They recruited patients that underwent induction chemotherapy, SCT, or GVHD treatment that had BD glucans throughout their stay while on posa or micafungin prophylaxis. They defined a positive BD glucan as 2 or more BDG
