Abstract

We evaluate the triphenyl tetrazolium chloride (TTC) dye reduction test for quicker diagnosis of urinary tract infections for its sensitivity and reliability to detect significant bacteriuria. Of the 1400 urine samples tested 780 (55.7%) had significant bacteriuria. TTC dye test was positive in 678 (86.9%) of those with significant bacteriuria thereby showing its usefulness. The test is simple and cheap and can be carried out in field situations.
