No

No. There is zero chance of that. If your potassium level is high, then there are one of two problems:

1) You have kidney problems

OR

2) The blood sample was damaged and it released the intracellular potassium into the sample, thus making artificially high levels. This is an EXTREMELY common problem in blood tests.

If you have normal kidney function (your BUN and Creatinine levels are normal on your blood test), then just have them run the blood test again. It's almost certainly just a damaged blood sample- again, a VERY common problem in blood tests. I've collected probably HUNDREDS of samples that hemolyzed and showed a high potassium level on the test. Just get the test redone.
