Abstract:
To determine the optimal number of specimens for virus detection in a respiratory outbreak, laboratory results from 2 Canadian public health laboratories were reviewed. The evidence suggests that 3 specimens are sufficient for detection of a virus in >95% of outbreaks, thereby reducing laboratory costs.

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,...
