Hi,

I am a little concerned about my last two blood tests as my potassium levels are a little high but my GFR for kidneys was 79 which they say is normal.

I went to the doctor on Friday last week because I was having wheezing after a hard work out on Monday and I started to get a sore spot on my right chest so the doctor sent me for an EKG, blood, and xray and they all were normal except the Friday blood test had my potassium at 5.4 so the doctor called me yesterday and said everything was normal except my potassium and then she asked me if I'm taking any supplements to which I replied no except a men's vitamin called Active X and 4000 IUs of vit D. She said it could be a false positive so sent me for another blood test and it came back at 5.0. Now 5.0 is considered normal but it is at the threshold of high, and I'm a little worried because I had this happen a couple of years ago and the doctor at that time said it happens all the time because of how they handle the blood sample so he sent me back for a repeat a day later and I was normal, but this time it is high normal.

My GFR was 79 and blood pressure was excellent. I am 44 male and work out 4-5 days per week, and am healthy although my diet could be better. I like my beers on the weekend and I am trying to get to my goal weight of 170 lbs to which I am currently 188 lbs.

Does anyone have experience with this?

Thank you,
