The clinical test nitrite is a test used to detect the presence of nitrite in a patient's urine. Nitrite is a byproduct of bacterial metabolism and is an indicator of a urinary tract infection. The test is performed by collecting a urine sample from the patient and then testing it for the presence of nitrite. The most common method for obtaining a urine sample is to have the patient urinate into a clean, dry container. The sample is then tested using a nitrite dipstick, which is a small plastic strip that contains a chemical that changes color when nitrite is present. The color change is then compared to a color chart to determine the amount of nitrite present in the sample.
