The mean cellular volume (MCV) of urinary red blood cells (RBCs) of pediatric patients with glomerular (group I; n = 52) and nonglomerular (group II; n = 21) hematuria was determined using an automated bloodell analyzer. Group I patients had a significantly lower MCV than group II (61 ± 8 w. 88 ± 15 μm3, mean ± SD; p<0.001). With a MCV of 75 μm3 taken as the dividmg line between glomerular and nonglomerular hematuria, correct assessment of the site of bleeding was made in 67 of the 73 (92%) patients studied. Determination of the MCV of urinary RBCs is a simple noninvasive test for localizing the site of hemaw in pediatric patients.
