The Study of the Value of Mean Corpuscular Volume in the Urine Red Blood Cell Phase in the Differential Diagnosis of Hematuria

Abstract

<p><strong>Objective: </strong>The changes of urinary red blood cell morphology and the average volume of red blood cell were examined by MCV. <strong>Method:</strong> In 100 cases of patients with urinary sediment microscopy of hematuria, and used blood cell analyzer for determination for MCV in urinary RBC. <strong>Results</strong><strong>: </strong>Renal hematuria MCV and the outer peripheral blood MCV has significant difference (<em>p</em> < 0.01) and non-renal hematuria and peripheral blood MCV had no significant difference, glomerular hematuria and non-glomerular hematuria erythrocyte deformity was significantly different (<em>p</em> < 0.01), renal hematuria MCV is less than or equal to 73 fL, abnormal red blood cells with 2 or more, deformity rate is more than or equal to 76%. <strong>Conclusion:</strong> RBC phase combined with MCV detection of urine RBC is the practical value in diagnosis of glomerular hematuria.</p>
