Abstract


Screening test is not for diagnose, but to determine whether the one who involved in this ailment sick or not. Then for those with positive result will be threating intensively. In order to prevent the infection. Because screening test is not for diagnose, there for it is requires direct follow up and appropriate treatment. The formulation of this research was the sensitivity and specificity’s values of gram negative rods invention with Gram staining as a screening test of urinary tract infection (UTI). This research was a cross sectional study, the samples of this research was 18-20 years old students of laboratory technician program in Polytechnic of Health Ministry of Health Mataram taken with consecutive sampling method. The urine culture as a Gold standard of urinary tract infection (UTI) test. The result from this research shows that 8 samples with bacteria positive and 69 samples with negative result from 77 samples. The Gram staining from samples shows that 9 samples with positive result and 76 are negative. Urine microscopy test show 15 samples are positive leukocyturia and 62 are negative. Sensitivity and specificity value present from the 2 x 2 chi – square table. Sensitivity value is 75.05% and specificity is 80,51%. Gram staining of urine without centrifugation result is higher than leukocyturiaurine.
