The simple visual inspection of urine may be just as accurate as standard laboratory tests in determining if there is a urinary tract infection (UTI) present, according to a new study.
Researchers obtained urine samples from 159 patients ranging in age from 4 weeks to 19 years.
They note that "The finding of clear urine on visual inspection had a negative predictive value of 97.3%. These results were similar to those obtained with standard urinalysis."
"Clear urine on visual inspection cannot completely eliminate the possibility that a child has a urinary tract infection. However, it is a reproducible test that offers the advantages of being simple, fast, and inexpensive. The finding of clear urine should be considered a reasonable and relatively effective bedside screen for the presence of a urinary tract infection," the authors conclude.
