ckd depends on more than protein in the urine..labs also can be off..have them retaking say 2 times a month..mine was 1.0 1 time then next time 1.3....ur bun, gfr, among others account for the creatine levels...do you have foam in ur urine thats a sign of protein in urine...you need to recheck this at least 2 times then waite 3 monthes to see whats going on..if urs is that then others will follow like ur gfr rate anything below 59 is to be watched for a 3 month period...im a advocate not a m.d.
Your creatinine can also be based on your height and how much you exercise.
The bigger the muscle mass we have the higher our creatinine will be.
So, if you're tall and exercise daily creatinine of 120 might be normal for you.
It's hard to diagnose you with just one test. The test will have to be repeated numerous times within the next few months, so see it that 120 was a one time or if it stays at that #
