Abstract
A multicentre evaluation of the urine analyser Miditron(R) Junior was performed at four laboratories. The Miditron(R) Junior analyser provid es semi-quantitative results for erythrocytes, bilirubin, urobilinogen , ketone bodies, glucose, protein, nitrite, leukocytes, pH and relativ e density. Accuracy of the Miditron(R) Junior analyser was evaluated b y comparison to quantitative analytical chemistry methods (glucose, to tal protein), physical methods (pH, relative density), and microscopic methods (erythrocytes, leukocytes). Agreement was defined as identica l or neighbouring concentration block. The level of agreement found wi th chemical, physical or microscopic methods for the six analytes test ed varied from 79 to 99%. The within-run precision was determined as r epeatability by using 31 native urines. The results of repeated measur ements (n=10) fell in the same concentration block, or in case of bord erline concentration were spaced between two adjacent colour blocks. D ay-to-day precision covering a minimum of 20 days using commercially a vailable control solutions yielded results within +/-one colour block from the mean.
