A serum creatinine test — which measures the level of creatinine in your blood — can indicate whether your kidneys are working properly.
The normal range for creatinine in the blood may be 0.84 to 1.21 milligrams per deciliter.
In general, high levels of creatinine in blood and low levels in urine indicate kidney disease or another condition that affects kidney function.
But abnormal results don't always mean kidney disease. You can check whether you have the following conditions:
·A diet high in red meat
·Certain medicines. Some medicines have side effects that raise creatinine levels.
Creatinine level of 2 is higher than the normal standard, you’d better see a nephrologist. Wish you all the best！
