The Assessment of the Clinical Significance of the Source of RBC in Patients with Hematuria by Hematoanalyser

Red blood cell volume distribution curve （RDG）, mean corpuscular volume （MCV） and red blood cell volume distribution width （RDW） in urine were measured in 44 cases with glomeruloneph ritis and 39 cases with non-glomerulonephritis and their clinical significance on differentiating hematuria were observed. The results showed that there were obvious difference between glomerulonephritis and non-glomerulonephritis about the characteristic of the RBC. The MCV （average） were 60.26±12.57 f1 and 80.56±15.9f1 respectively. if 72f1 was used as a standard to differentiate glomerulonephritis and non-glomerulonephritis. The sensitivity and specificity of differentiating hematuria were 84.1％, 84.0％ respectively. There was less clinical significance with RDW in differentiating glomerulonephritis and non-glomerulophritis.
