Who should get a potassium test?

A potassium test is recommended for individuals with symptoms like muscle weakness, fatigue, irregular heart rhythms, or high blood pressure. It is also essential for people with conditions like kidney disease, heart disease, or adrenal gland disorders, as these can affect potassium levels. Individuals taking medications like diuretics, which alter potassium levels, should also get tested regularly. Additionally, those undergoing treatment for dehydration or electrolyte imbalances or with chronic illnesses like diabetes may require periodic potassium testing to monitor their health.
