(I guess you meant "creatinine" levels?) Normally in the lab tests for kidney function, the creatinine, urine albumin, BUN and GFR levels are tested. You can check online lab sites for the 'normal' parameters for these tests. And please have your doctor explain to you what your test results mean, if you need further testing, etc.
Check out this website explaining these tests. https://www.healthline.com/health/kidney-function-tests
Keeping your blood pressure and blood sugar at normal levels help to prevent chronic kidney disease, so learn what your blood pressure is, and have your blood sugar tested for diabetes. Even elevated or what they call "prediabetes" can affect kidney health.
The best advice I can give you is to return to your doctor for more information and find out if your blood pressure and blood sugar levels are normal. If this information is not given to you or tested by your doctor and lab tests (for blood sugar), then find another doctor.
And, always get hard copies of your lab work whenever/whatever is done. Keep these in a "health" file in your home for future reference.
