Aberrant red blood cells usually refers to non-homogeneous red blood cells, 40,000 aberrant red blood cells/ml in urine test is usually more serious, suggesting that the urine contains a large number of non-homogeneous red blood cells. If the proportion of non-homogeneous red blood cells in the urine is too high, the main consideration is renal hematuria, which is common in diseases such as glomerulonephritis, and the condition is usually more serious. When the proportion of non-homogeneous red blood cells is too high, it mostly suggests that the hematuria is dominated by non-homogeneous red blood cells, and then it is often considered as renal hematuria, which is mostly seen in glomerular and tubular injuries and other causes, such as glomerulonephritis, nephrotic syndrome and other diseases. If the number of aberrant red blood cells is small, then consider that the hematuria is dominated by homogeneous red blood cells, and consider that it is non-glomerular hematuria, which is commonly seen in urinary tract infections, stones, and tumors. If the number of aberrant red blood cells in the urine test is found to be high, it is recommended that the patient go to the hospital in time, under the guidance of the physician to actively improve the relevant examinations, and comply with the doctor’s instructions to standardize the diagnosis and treatment, so as to avoid delaying the condition.
