Hello doctor, This person is 43 years old and male. He takes weekly urine screen at the same time of each week. The screen measures creatinine in mg/dL and the previous creatinine results are as follows: 117, 221, 179, 88, 147, 235, 201, 173, 100, 92, 123 and 142. About a year ago, he had levels as low as 17 and 22. Are these normal range of numbers? If not, what might explain this person's wide range in creatinine? The tests are to monitor for alcohol use and I believe there is a possibility that this person is falsifying the tests. If you know any studies, then you could point me to that to have a look at creatinine variations in healthy adults that would be helpful. Thank you.
