Abstract
The presence of nitrite was initialy assessed in 306 specimens of urine. If the initial result was negative a sample of urine was incubated at 37°C. The other portion was also incubated but with the addition of one drop of 1% NaNO3, and the nitrite test was then repeated. The results were correlated with the results of quantitative routine urine culture. The modified test significantly (P<0.01) improved the sensitivity (93% v 21%), and the predictive negative value (97% v 80%).
