Why is creatinine level used to indicate dialysis?
Our kidneys play a very important role for a healthy body. It helps to regulate blood pressure, maintain electrolyte balance, purify blood and produce urine, so when kidneys fail to function properly, various medical problems will appear. Failed kidney can not remove toxins out of the body any more when they are damaged severely, so large amounts of toxic substances will build up in the blood at that time. Dialysis is needed by kidney failure patients because it can replace failed kidney to purify blood, so as to maintain the normal function of our body.
Creatinine is one of the wastes in the body that need to be removed by kidney, so when kidney failure is always accompanied with high creatinine level in blood. In general, the higher the serum creatinine level, the poorer the kidney function, the higher the toxin levels in the blood and the more emergency for patients to do dialysis.
What creatinine level indicates dialysis?
Generally speaking, kidney failure patients need to prepare for dialysis when their creatinine level becomes higher than 5, but of course, dialysis is not a must at at that time. If they have no symptoms like fluid retention in lung, severe vomiting and severe skin itching, they can delay dialysis. Also, if they have good urine output at that time, there is great chance for them to avoid dialysis completely if they can take right treatment as quickly as possible. (You can consult our online doctor for medical suggestions about your illness, so as to make sure you are getting the right treatment).
Serum creatinine level is just one of indicators for dialysis, apart from it, potassium level in blood is also a very important. High level of potassium in blood is extremely harmful for heart, so dialysis is also recommended when potassium level in blood is as high as 6.5mmol/L. Any questions, please leave us message below
