Looking at the Color of Your Urine Can Diagnose an Infection or If You're Dehydrated
November 26, 2000
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.
