Question about creatinine level

Is 70.3 mg/dL something to worry about? Google confuses me, by the time I Google something else to figure out what it is, and go back, I have to Google something again because I...

So, should one be concerned with that? The month before was 81.2 mg/dL, and month prior to that was 87.2 mg/dL

I ask because someone asked me if I had mine checked recently, why I'm not sure. I could have remembered wrong, he could've asked if I tested something else. But when I seen this on some results, I googled it. And here I am. Either I'm really high and should be gone, or I'm dangerously low and will be gone before you finish reading this.

I seen something about disease, wasting muscle disease, other stuff. Just wondering if those are normal a 33 year old man, or no? I'm also 155 if that matters. I don't know. Should I be worried? Tia.
