Serum B-glucan for diagnosing PCP

In this cohort of HIV patients with PCP, a serum B-glucan level >23 pg/mL (the threshold of detection for that assay) had a sensitivity and specificity of 96% and 88% respectively (over half of these patients also had candidiasis). Of note, the level did not correlate with severity of hypoxia, serum LDH, or response to treatment. Serum B-glucan is a sensitive and specific diagnostic test for PCP in HIV patients (abstract).
