Urine Culture - Nitrite: - Conversion of nitrates to nitrite; - Positive: infection (negative test does not rule out infection since some organisms such as Strep faecalis & other gram positive cocci will not produce nitrite, & note that urine must also be retained in bladder for several hours to allow the reaction to take place;
- Leukocyte Esterase: - Test detects 5 or greater WBC/HPF or lysed WBC's; - When combined w/ Nitrite Test, it has a predictive value for UTI of 74% if both pos, and >97% if both Tests are Negative; - Positive: Infection False Pos with Vaginal contamination;
