What a low potassium usually means, and its common causes
When a potassium can read wrong
Potassium is the result most often thrown off by the sample. Cells that burst in the tube, a tight tourniquet, clenching your fist, a long wait before the sample is spun, or a very high platelet or white cell count can all make it read high when your blood isn't.

Questions
Is a potassium of 3.2 mmol/L normal?
A potassium of 3.2 mmol/L is in the 3.0 to 3.4 mmol/L range usually called mildly low. The usual range is about 3.5 to 5.0 mmol/L (some labs go to 5.1 or 5.3).
Is a potassium of 3.2 mmol/L dangerous?
Between 3.5 and 5.0 mmol/L is the usual range. Just above 5.0 is most often a sample that burst in the tube; 6.0 and over, or under 3.0, is a same-day call to your doctor.
Can bananas raise potassium to 3.2 mmol/L?
Not in people with healthy kidneys, which clear the extra quickly. With reduced kidney function, or on medicines that hold potassium, diet matters more.
