Sampling variability in the microbiological evaluation of expectorated sputa and endotracheal aspirates
Abstract
A five-center study was conducted with the aim of determining how reproducibly expectorated sputa and tracheal aspirates could be sampled when preparing Gram-stained smears and inoculating cultures. With both specimen types, excessive variation was noted among Gram stain results obtained from replic …
