For kidney transplant patients, it does not matter what is your creatinine level. What is important is whether your creatinine is stable. For example, if your creatinine is steady around 0.9, then it is very good. If your previous creatinine level is 0.5, and this time you got a creatinine level of 0.92 (although normal in absolute numbers), it still suggests something wrong, such as you may have a rejection. So look at creatinine changes rather than the value itself in kidney transplant recipients!
