In brief: Blood test

High and low blood levels of potassium may actually have similar symptoms e.
g. Muscle fatigue or cramps. There is no substitute for blood test. Taking excessive amounts of otc potassium pills for cramps is dangerous since if you have high levels of blood potassium it may be compounded causing heart muscle problems.

In brief: Testing

Other than a blood test there is not a reliable way to know.
Ekgs are used too but they aren't specific and don't catch everything. By the time someone has a obvious side effect to a very very high or very very low potassium level it is likely life threatening. Symptoms often associated with mild potassium abnormalities are common and correctioning potassium level doesn't always resolve them.
