RAPID URINE SCREENING FOR BACTERIURIA IN CHILDREN USING MICROBIOLOGY ANALYZER, COMBINING PHOTOMETRIC AND COHERENT FLUCTUATION NEPHELOMETRIC METHODS

One of the most widespread microbiological analyses in clinical practice is urine culture, and up to 80% of urine samples turn out to be negative. In this study we demonstrate applicability of coherent fluctuating nephelometry (CFN) method for rapid urine screening and negative samples identificatio...
