What is the normal number of red blood cells in a urine test?

When you go to the hospital for a urine test, if you find that there are too many red blood cells in the urine, you should be alert to some urinary system diseases, such as kidney disease and urinary stones, etc. Patients need to judge based on their own situation, such as whether they feel pain, whether they have symptoms such as urinary pain and frequent urination when urinating. In order to find out the cause, further examination may be needed. So under normal circumstances, what should be the number of red blood cells in the urine?

What is the normal number of red blood cells in a urine test?

Urine is a very important excretion of the human body. Whether urine is normal reflects a person's physical health. Normal urine test results do not show red blood cells. If a person's urine test results show that there are too many red blood cells, then it means that the urine is abnormal and there must be something wrong with the body. So, what is the normal red blood cell count in a person’s urine test?

Normal urine test red blood cell count

Normal urine generally contains no red blood cells or only a small amount of red blood cells. Urinalysis examination should show less than 3 red blood cells per high-power field, less than 500,000 red blood cells in 12-hour urine, or less than 8,000 red blood cells per milliliter of urine. If the above limits are exceeded, hematuria can be diagnosed.

What causes high red blood cells in urine?

Through urine examination, it was found that the red blood cell level was high. There are usually three types of red blood cell shapes in urine. One is deformed red blood cells, in which case the red blood cells are mostly leaked from the kidney, mainly due to nephritis and other conditions; one is normal red blood cells, in which case the red blood cells are mostly caused by extrarenal bleeding, mainly due to ureteral, bladder and other lesions; one is a mixed type, which includes both of the above shapes. At this time, other medical history needs to be analyzed to determine the cause.

If the hematuria is simple dysmorphic erythrocyte urine, without proteinuria and hypertension, it may be mild glomerulonephritis, but it usually gets better later. More than 95% of patients will not develop the disease and usually do not need medication. Because the effect of erythrocyte urine itself on the kidneys is slight, far less than the effect of drugs on the kidneys, this is why it is not recommended to treat simple erythrocyte urine at that time.

This article introduces in detail the normal number of red blood cells in a normal person's urine test, and also explains what is going on when there are too many red blood cells in a urine test.
