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 replicate smears. Less variation was noted among culture results, especially with tracheal aspirates.
一项五中心研究开展,目的是确定在制备革兰氏染色涂片和接种培养物时,咳出的痰液和气管吸出物的采样可重复性如何。对于这两种标本类型,从重复涂片获得的革兰氏染色结果之间存在明显差异。培养结果之间的差异较小,尤其是气管吸出物。
