Creatinine level can become higher and higher along with decrease of renal function. In clinic, it is usually taken as an index to reflect how well your kidneys are functioning. Well then, what levels of creatinine would indicate kidney disease? Now, follow me and see the answer.
what creatinine levels indicate kidney disease?
Normally, the healthy kidneys are responsible for filtering extra wastes and toxins including extra creatinine from the body effectively. And they can keep creatinine level within the normal ranges: 0.5-1.1mg/dl for females and 0.6-1.2mg/dl for males. Our kidneys is composed over one million nephrons which is mainly composed of renal tubule and glomerular. When only a small part of nephrons are damaged, creatinine does not increase at all, as the other nephrons can help to remove the excessive creatinine out of the body. According to clinical experiments, creainine level increases when about a half of renal function is affected. Therefore, in cases of chronic kidney failure, high creatinine level always indicates kidney functions have been affected seriously. Generally speaking, if creatinine level is in 5.1 to 7.9ml/dl or 442 tp 707umol/L, it suggests patients are in Kidney Failure stage.
However, should I be concerned with slightly high creatinine level?
Because high creatinine level can imply kidney disease, hence, some patients are worried when they have elevated creatinine level occasionally. Actually, elevated creatinine level also can be caused many conditions like improper diet, strenuous exercises before tests. Other conditions like dehydrate, medications also can induce slightly elevated creatinine level. Therefore, creatinine is not the most reliable indicator to reflect kidney function. Here GFR (glomerular filtration rate) is more reliable indicator. When GFR decreases to 50ml/min or even less, patients are prone to suffer from corresponding symptoms.
