Summary
In a blind-study with 96 patients analysis of erythrocyte diameters permits to differentiate between renal-parenchymatous and post-renal microhaematuria in 89,9% of the cases.
Erythrocytes on renal-parenchymatous microhaematuria are distinctly smaller (Average diameter 3.2 µm-5.6 µm) than those on post-renal microhaematuria (average diameter 5.4 µm-8.8 µm).
In addition to the evaluation of erythrocyte morphology erythrocyte morphometry represents further possibility in diagnosis.
