Urine should not contain red blood cells. What should I do if red blood cells are found in my urine during a hospital examination? First of all, don’t panic. This situation may be caused by blood in the urine, which may be caused by a urinary tract infection or other disease. Consult a doctor promptly and conduct other examinations. Only after finding the cause will you know how to treat it. Red blood cells are the most numerous formed elements in the blood. Their main physiological function is to act as respiratory carriers to carry oxygen to tissues throughout the body and to maintain acid-base balance. This function is accomplished by the hemoglobin it contains. Hemoglobin is a reddish colloidal substance composed of globin combined with ferrous heme, and its molecular weight is 64458. It is a respiratory carrier and each gram of hemoglobin can carry 1.34 ml of oxygen. Studies have found that the diameter of quasi-mature red blood cells is 6.7-7.7μm. They are disc-shaped when viewed from the front and appear as a single or double concave disc when viewed from the side. This shape is conducive to the completion of the physiological functions of red blood cells. Because: ① The cell membrane has a large area, which is convenient for gas exchange; ② The cell membrane has a surplus, which ensures that red blood cells can easily stretch and deform. Although its diameter is 6.7-7.7μm, it can smoothly pass through the splenic sinus with a diameter of only 3μm. Pay attention to personal hygiene, keep the vulva clean and dry, change underwear frequently, and use vulva equipment for one person only. Used underwear, towels, and basins should be washed with boiling water and exposed to the sun. Normal human urine does not contain red blood cells or the number of red blood cells is extremely small. Due to reasons such as the kidneys, bladder or ureters, red blood cells may enter the urine, increasing the number of red blood cells in the urine. In mild cases, occult blood in the urine will occur, while in severe cases, gross hematuria will occur. Disease indicators Therefore, macroscopic hematuria contains more blood and is more serious than microscopic hematuria. Normal range: <3 per high-power field. In addition: When the urine red blood cells are >10, the urine occult blood will show positive (+). Clinical significance: Common causes of hematuria include acute glomerulonephritis, chronic nephritis, acute pyelonephritis, and urinary stones. Tuberculosis, tumor, trauma, etc. If there is simply a large amount of hematuria, the possibility of stones is greatest. Pathological causes Erythrocytes, which are red blood cells that appear in urine. Polycythemia vera is caused by bleeding in the urinary system (kidneys, bladder, or ureters), with blood entering the urine. This type of urine specimen is also called hematuria, which is divided into gross hematuria and microscopic hematuria. Macroscopic hematuria is urine that is visible as blood to the naked eye. When there are >3 per high-power field, but the urine does not appear bloody, it is called microscopic hematuria. |
