What is a dangerous creatinine level?


Answer by  Ginny (2251)

Reference ranges for creatinine levels vary by age and body type, but normal for women is 0. 5 to 1. 0 mg/dl, for men 0. 7 to 1. 2 mg/dl. Muscular adults will have more. Elderly have less. Levels of over 10. 0 are dangerously high in adults.

My 84 year old Mother was given a baseline of 170-210, is that dangerous?  add a comment

Answer by  FreddieR (104)

The short answer is anything over 1.0 mg/dl (milligrams per deciliter of blood) is considered dangerous, although your doctor would probably say a level of up to 1.2 mg/dl is okay if you are a male in excellent physical condition. The older and less muscular you are, the lower the level should be.

Anything over 1.0 would be considered dangerous. The appropriate range varies based on body type and gender, so consult with a doctor if you are concerned.


Answer by  kezza (23)

Creatinine is found in a person's blood and urine. It measures how well a person's kidneys are functioning. A rise in creatinine level indicates a problem with a person's kidneys. A dangerous level varies depending on a persons' age and body type. Generally a measurement over 1.0 is worthy of concern.

Dangerous creatinine levels differ with age, the older you become the lower that level will become. Ideally a creatinine level around one is okay, however a level less than one and a half in a young adult is alright. It is hard to determine a definite number but if you follow these guidelines you should be fine.


Answer by  MaryM (25)

Creatinine can be measured in the blood or urine. Normal levels are 0. 5 to 1. 1 mg/dL. Any rise in creatinine 0. 5 or above normal levels can indicated a problem with your kidneys and therefore could be considered dangerous.

my creatinine level is suposed to be in a reference range of (0. 40-1. 10). mine is 1. 40 and flagged as HIGH. Should I be concerned?  add a comment

It depends on the age. In older adults, there is a much lower verge for high creatinine, because creatinine relies on ratio of muscle mass to fat mass. The higher the muscle mass, the higher the creatinine.

Despite what some claim here, most labs state the normal range for males is up to 1.2, some labs state 1.4. Its really disgusting how people can post nonsense on the web to try and scare people. It also varies from each test.
