Help with my blood tests and the way I am feeling

Hi Everyone,

My name is Mike, I am 41 male. I have had some muscle twitching and brain fog for about a month, and I went to my GP and he sent me for blood work, and it came back that my potassium level was high 5.7, and that I my GFR was 76.

My urea is 5.4 and my creatine is 104.

My fasting glucose is high at 5.8, and my cholesterol is 5.37.

The blood test was a fasting blood test and I didn't eat or drink anything for about 13 hours.

Is this indicative of CKD? I have noticed that my GFR has decreased from 87 to 76 in about a year.

I do have some health anxiety, and I have been pretty stressed out from this twitching. This twitching has seemed to be really bad today in my left knee MCL muscle, and my middle finger. it is very constant.

Can someone give me some advice as what this means?

Thanks
