Consistent assignment of urine test strips categories to the respective concentration or concentration ranges of measured analytes is not only a crucial prerequisite for comparability of results between medical laboratories, but also for a longitudinal comparability of results in the same laboratory. Reference Institute for Bioanalytics (RfB), Institut für Standardisierung und Dokumentation im medizinischen Laboratorium (INSTAND), Labquality) also use categorized scale for reporting urine test strip qualitative analysis results, without declaring accompanying concentrations or concentration ranges.

Moreover, most external quality providers ( e.g. However, respective concentrations or concentration ranges for measured analytes have not been provided by CCMB and it is thus, up to the laboratory to decide which category to assign to particular concentration of analyte in urine. In Croatia, in line with the recommendation of the Croatian Chamber of Medical Biochemists (CCMB), medical laboratories report the results of urine test strip qualitative analysis using the categorized scale with a defined number of categories ( Table 1) ( 1). It is often up to the medical laboratory to define their own categories and respective concentration ranges. Thus, most analytes measured by urine test strips have more measurement fields then categories commonly used to report test results. Most test strips have one field for negative result and various number of fields for positive results, in an increasing order of the concentration of an analyte. strip pad) on the test strip per analyte may vary. Depending on the manufacturer, the number of measurement fields ( i.e. Urine test strip analysis is a semi-quantitative analysis in which the concentration of an analyte is measured in urine and expressed as a category.
