Sandy i've not had the problem and i'm over 5 yrs out....how did they do the test for the creatinine level?...did you fast 8 hrs first?
As to the preparations that people would do before undergoing the test, there are a number of steps they need to take to make sure that the results of the test would be accurate. One of these is that people are encouraged to fast, which means no food or drink for a period of eight hours before the test. In addition to this, people are also advised not to take vitamin C, barbiturates, and diuretics 24 hours before the test, as these can affect the results of the test. As to the precautions that people need to be aware of, one of the most important is that a high diet of meat can also significantly affect the results of the test. Moreover, people are also discouraged to take medications that decrease Creatine levels in the body, as they can be toxic to the kidneys.
Results
For adult males, the normal Creatine level is 0.6 to 1.2 mg/dL, while for adult females, the normal level is about 0.5 to 1.1 mg/dL. With regard to abnormal results, physicians would suspect that something is wrong if the deviation from the normal level reaches about 2 to 4 mg/dL, which can mean that there is impairment in the renal function of the kidneys
