Understanding the Test Report:
Normal: 3.5 – 5.5 mEq/L
Low Potassium (<3.5): Muscle weakness, cramps, arrhythmias
High Potassium (>5.5): Kidney issues, medications, dangerous arrhythmias
Both high and low potassium can be serious.
Preparation and Procedure:
Routine blood sample
No special preparation required
How is the Test Done?
