normal range for blood creatinine
The normal range for serum creatinine (in the blood) is usually between 0.6 and 1.3 milligrams per deciliter (mg/dL) although it varies between labs, between men and women, and by age.... A high serum creatinine level means your kidneys aren't working well.f they are healthy, the kidneys typically keep blood creatinine levels in a normal range. As such, creatinine levels are a fairly reliable indicator of kidney function. If the kidneys become impaired for any reason, the creatinine level in the blood will rise.
