Possible Reasons For High Potassium On A Blood Test?

[Ryan999]

To specify my question even more, the blood test was for my brother who has muscular dystrophy (not sure if that would matter or not). The blood test was just a general one done by his PCP. His level was out of the normal range as 5.30 mmol/L.

if the muscular dystrophy produced ongoing activity,
it seems likely that the higher Potassium is some kind of "spill over"-event,
coming from the pool of K in the musculature.
