Single and multiple test combinations were studied to determine the accuracy of the standard urinalysis method in predicting sterile or contaminated cultures and cultures with significant bacteriuria from gram negative rods (GNR). The results demonstrated a significant incidence of microscopic bacteriuria and pyuria in GNR culture (P < .001) and an association between large numbers of epithelial cells and culture contamination. A discriminate analysis of multiple test combinations was done to identify the order in which urinalysis tests significantly improved the ability to discriminate between culture groups. Results indicated that multiple test combinations were more predictive than single tests. Based on study results, a cost-effective scheme for ordering urine cultures is proposed.
研究了单一和多种检测组合，以确定标准尿液分析方法在预测无菌或污染培养物以及革兰氏阴性杆菌（GNR）引起的显著菌尿培养物方面的准确性。结果表明，GNR培养物中显微镜下菌尿和脓尿的发生率显著（P <.001），并且大量上皮细胞与培养物污染之间存在关联。对多种检测组合进行判别分析，以确定尿液分析检测显著提高区分培养组能力的顺序。结果表明，多种检测组合比单一检测更具预测性。基于研究结果，提出了一种经济有效的尿液培养检测方案。
