[Differential diagnosis of hematuria on the basis of morphology of stained erythrocytes].

Glomerular and nonglomerular hematuria was differentiated in 40 patients by the morphology of erythrocytes stained with floxin in buffer solution. Glomerular hematuria was correctly diagnosed in 91.0%, nonglomerular in 88.9% of patients. The results of diagnosis of hematuria by floxin staining and by phase-contrast microscopy coincided; both methods are superior to the Right staining technique. The proposed method is easily available for any laboratory and is suggested for tentative diagnosis, in order to improve the diagnostic process.
