| Limitations |
Metabolites of Pyridium® may interfere with the dipstick reactions by producing color interference. High vitamin C intake may cause an underestimate of glucose, blood, bilirubin, and a false-negative nitrite test. A low ph can also result in a false negative for protein and WBC's. A false negative for WBC's also can occur with elevated specific gravity, glucose, and/or protein levels. An increased specific gravity may cause a false negative for blood and/or nitrites. False positives can occure for protein when hemoglobin is present and/or an elevated ph level. |
