Performance of Laboratory Testing in Culture-Confirmed Blastomycosis: A Retrospective Study
1Department of Pathology, Microbiology and Immunology, Vanderbilt University Medical Center, Nashville, Tennessee, USA.
Abstract:
This retrospective study evaluated diagnostic modalities in 51 culture-confirmed blastomycosis cases over a 10-year period. Urine antigen testing demonstrated variable sensitivity across disease types, whereas antibody testing with enzyme immunoassay, pathology, and fungal culture were essential for diagnosing antigen-negative cases. These findings highlight the importance of a multimodal diagnostic approach.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
