Performance of urinalysis tests in screening for significant bacteriuria among human immunodeficiency virus-infected subjects in South India

| 2017 | 1 Of the study population, 57.6% were females with mean age of 30.3 years (range, 4–66) and the rest were males with mean age of 38.6 years (range, 1–79). Most infections were due to Escherichia coli (10.7%), followed by other members of family Enterobacteriaceae, Staphylococcus aureus and Pseudomonas aeruginosa. Table 1 outlines the performance of the urinalysis tests for detection of significant bacteriuria. A positive urinalysis result (combining the LE, NIT and excluding microscopy) had a sensitivity of 57.4% and a specificity of 99.7%. On further analysis by including only the Gram‐positive uropathogens, the LE’s sensitivity and specificity dropped to about 72.2% and 68.5%, respectively. However, sensitivity and specificity of NIT including only the Enterobacteriaceae members modestly raised to 36.7% and 99.5%, respectively.
