Hypokalemia (Low Level of Potassium in the Blood)
Diagnosis of Hypokalemia
Measurement of the potassium level in the blood Electrocardiography Sometimes measurement of the amount of potassium in urine The diagnosis is made by measuring a low potassium level in the blood. Doctors then try to identify what is causing the potassium level to decrease. The cause may be clear based on the person’s symptoms (such as vomiting) or use of medications or other substances. If the cause is not clear, doctors measure how much potassium is excreted in urine to determine whether excess excretion is the cause. Because low potassium levels can cause abnormal heart rhythms, doctors usually do Electrocardiography (ECG) to check for abnormal rhythms.
