Urine erythrocyte count 5.2/HP is not normal, urine erythrocyte count is normal <3/HP. Excessive erythrocytes detected in urine can be seen in physiological factors, such as strenuous activities, staying up all night, etc.; can also be seen in pathologic factors, such as glomerulonephritis and urinary tract infections. 1. Physiological factors: strenuous exercise, fever, late at night, nutcracker syndrome, etc., can lead to abnormal red blood cells in the urine, at this time there is generally no need for special treatment, pay attention to rest, regular review can be. 2. Pathologic factors: urine red blood cells are divided into glomerular origin and non-glomerular origin. (1) Glomerular origin: when the red blood cells pass through the glomerular filtration membrane, they are squeezed and damaged, and are affected by pH and osmotic pressure changes in the renal tubules, showing polymorphic changes. It is common in internal diseases, such as acute glomerulonephritis and chronic nephritis. (2) Non-glomerular origin: erythrocytes are homogeneous in morphology, similar to those in peripheral blood, and in the form of biconcave discs, which are commonly seen in urological diseases, such as urinary stones, tuberculosis, tumors, and infections. Patients with abnormal urinary red blood cells are advised to consult regular hospitals and standardize treatment under the guidance of physicians.
