[An outside assessment of the quality of studies on the chemical composition of the urine within the framework of a single federal system].
The National External Quality Assessment Scheme for analysis of the urine is presented. It includes 9 parameters: protein, glucose, creatinine, urea, uric acid, sodium, potassium, hemoglobin, and pH. Two lyophilized of liquid control samples of urine (normal and abnormal) are distributed to the participating laboratories. An original evaluation protocol for qualitative and semiquantitative methods is proposed in addition to the traditional statistical approach to evaluation of the results of quantitative methods.
