ABSTRACT
Although culture is the gold standard for diagnosis of urinary tract infections (UTI), microscopy of well mixed drop of urine and several different dipstick rapid tests have become popular over the years, as culture is expensive, time consuming and requires a well-established microbiological laboratory and technical expertise. Rapid screening is also required in special circumstances, not only where it is difficult to identify urinary tract infection (UTI) on basis of clinical criteria alone but also where early diagnosis and prevention of complications affords significant benefit. This prospective cross sectional study was carried out in the Department of Microbiology of Government Medical College, Srinagar. A total of 800 patients were taken up for the study. Samples following the inclusion criteria were included in the study. Gram staining, wet mount for detection of pus cells and urine culture was performed. Data was compiled and compared with culture as gold standard for diagnosis of UTI.
Results: wet mount examination for detection of pyuria was done on all 800 samples taken up for study which gave sensitivity, specificity, positive predictive value, negative predictive value of 75%, 55%, 37.14%, 86.32% respectively when compared to conventional culture. Gram staining for detection of bacteriuria was also done on all 800 samples and showed sensitivity, specificity, positive predictive value, negative predictive value of 90%, 89%, 74.51%, and 96.17% in comparison to culture.
Conclusion: Although urine culture is used as the reference standard to determine the presence or absence of urinary tract infection (UTI), but it is an expensive and time consuming method. Substituting rapid diagnostic tests for a hospital laboratory urine analysis may be less time consuming and less expensive.
