I would like to know what happens if during a regular orine check the erythrocytes is found very high?

Question

also how dangerous is that

Answer 1

So an increase in erythrocytes in the urine can be considered normal if they are after trauma or instrumentation.

Many patients with kidney stones can also be found to have some hematuria.

If these do not apply, then, it is proper to repeat the sample in a short period of time to confirm the finding and then you should be tested for some of the causes of microscopic hematuria.

The small list of items that you do not want to miss include:
Transitional Cell Carcinoma (Cancer) - uncommon except in smokers and dye workers
Hypertensive Nephropathy
Nephritic Diseases of the Kidney : SLE, Goodpasteurs, PSGN, etc.

Some advise, get a repeat test and then do the blood work, these conditions are possible but relatively rare.

Answer 2

Do you mean urinalysis?? Erythrocytes are red blood cells, and red cells in the urine is called hematuria. It can be as little as trace hematuria (few cells and detectable only by microscopic exam) and as much as gross hematuria (obviously bloody urine). Hematuria can be an indicator of infection, trauma or urinary calculus.

I don't know what YOU mean by very high but a number would have been helpful to me.
