Highly fluctuating potassium levels
Hi there!
I recently went into my annual PCP visit and the blood work showed I was on the high end of normal for potassium (5.2). I did labs again and it went up to 5.3, then all the way to 5.9 during the third draw. I just did labs for a fourth time and it came back down to normal (4.7). I did these labs all within at least 2-4 weeks of each other. I am 28F and all of my other labs have come back normal.
I've read that potassium can be a bit finicky during blood draws and false high readings can be common. I'm wondering if anyone has had a similar experience to this, or what highly fluctuating potassium levels could point to? When my third blood draw came back as 5.9, I was quite concerned. Now that it's back down to normal range, I'm just puzzled!
