What are the reasons for high red blood cells in urine test

When we do a checkup at the hospital, we usually do a urine test. The urine test is mainly to check the kidneys. If the red blood cell count is high, there is a high possibility that there is a problem with the kidneys. If you have kidney disease, it can be very dangerous. Some kidney diseases may lead to kidney failure and loss of life. So if you find that your red blood cell count is high, you must pay attention.

However, for those who have not learned about kidney disease, they certainly don’t know the reasons for high red blood cell levels in urine tests. Here I will introduce to you the reasons for its appearance, and I hope that you can understand and gain something after reading it. If you have other knowledge you want to know after reading this, you can also read other articles. Routine urine test items can be roughly divided into four categories: the most important of which is kidney disease examination. In kidney disease projects, the normal reference values ​​for red blood cells in urine tests are: 4.6-8.0, 1.005-1.030, positive, negative, light yellow to dark yellow. Changes in these indicators may indicate renal impairment.

Occult blood, clinical significance: positive or increased, seen in urinary system stones, infection, tumors, acute and chronic nephritis, thrombocytopenic purpura, hemophilia, etc.

Tail-shaped epithelial cells: mostly come from the renal pelvis, and sometimes from the ureter and bladder neck. The presence of these cells in urine makes it difficult to determine the location of the lesion.

Epithelial cells. Normal human urine may contain a small amount of desquamated epithelial cells. The number of epithelial cells in the urine increased significantly, suggesting that there was a lesion at the site where the cells fell off.

Squamous epithelial cells: They come from the urethra. The presence of these cells in urine indicates inflammation of the urethral mucosal surface. A small amount has no clinical significance.

Small round epithelial cells: come from the renal tubules. It can also come from the deep mucosa of any part of the urinary tract. Therefore, it is difficult to determine the location of the lesion when these cells appear in the urine. If such cells are seen in casts, it is a strong basis for diagnosing renal tubular disease. In the case of rejection after kidney transplantation, sheets of small round epithelial cells may also appear in the urine.

This is all I have to say about the reasons for high red blood cell count in urine tests. I believe that friends who have read this should have a certain understanding of this. If you find that your urine test shows high red blood cells, don't panic too much. See if you might have made a mistake. If you are afraid of making a mistake, you can check again to make sure the value you get is accurate.
