Helloo everyone! I'm here to answer Ms Chew's question for me..
Sigificance of Nitrite dipstick test in Urine FEME
The presence of nitrite in the urine indirectly indicates that there is nitrite-releasing bacteria present. This test depends on the conversion of nitrate to nitrite by nitrate reductase, an enzyme usually produced by gram-negative bacteria. A positive nitrite test is shown by a pink colouration in the nitrite test region on the test strip, indicating bacterial infection. Not all kinds of bacteria releases nitrite. However, if bacteriuria is significant but WBCs are absent when viewed microscopically, the bacteria formed may be due to contamination because of wrong collection or handling method. Hence, bacteria should not be reported.
That's all folks!
