Examinations
Water for dissolution
Important Notes
Only in connection with scheme 3130
Clinical Chemistry
Specimens
1 lyophilised urine, 15 mL
Examinations
Particle count: erythrocytes and leukocytes. Estimation of density: creatinine, relative density, osmolality. Strip tests: glucose, ketone bodies, leukocytes, nitrite, pH, protein, blood (erythrocytes)
Important Notes
Also suitable for automatic analysers (erythrocytes and leukocytes counting). The arbitrary concentrations of the obtained strip test results will only be collected in order to avoid different groupings of positive categories used by different strip tests and user laboratories. Water for dissolution of the lyophilized sample available, see scheme 3131, should be ordered separately. 3 results processed
