Urine samples were obtained from a cohort of 78 subjects undergoing evaluation for suspected invasive fungal infections, and stored frozen until testing. Urine was processed by centrifugation through desalting columns and exposed to dipsticks. Reviewers blinded to clinical diagnoses graded results. Western blots were performed on urine samples from 2 subjects to characterize mAb476-reactive antigens.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Per-patient sensitivity and specificity for diagnosis of proven or probable IA in the overall cohort was 80% (95% confidence interval [CI], 61.4%\u201392.3%) and 92% (95% CI, 74%\u201399%), respectively. In the subgroup with cancer, sensitivity was 89.5% (95% CI, 66.7%\u201398.7%) and specificity was 90.9% (95% CI, 58.7%\u201399.8%); among all others, sensitivity and specificity were 63.6% (95% CI, 30.8%\u201389.1%) and 92.9% (95% CI, 66.1%\u201399.8%), respectively. Eliminating lung transplant recipients with airway disease increased sensitivity in the noncancer cohort (85.7% [95% CI, 42.1%\u201399.6%]). Semiquantitative urine assay results correlated with serum galactomannan indices.
