Kidney values in the laboratory and blood count
The kidney function is mainly controlled by appropriate blood tests. Usually two tubes of blood are taken from the patient and examined in the laboratory. Particularly important is creatinine, which increases in the blood when kidney disease occurs.
Furthermore, the potassium value and urea should be determined. These values are also increased if the kidney is not working in the usual way. A kidney function check therefore includes blood count and clinical chemistry (creatinine, urea and potassium).
Depending on the level of the values, a close monitoring must be carried out. If there is a sudden explosive increase in creatinine, acute kidney failure must be assumed. In this case, however, the lack of fluid is usually responsible and should be compensated as soon as possible.
