Potassium Test

The Potassium (K⁺) Test measures the level of potassium in the blood, a crucial electrolyte that helps regulate nerve signals, muscle contractions (including the heart), and fluid balance. Proper potassium levels are essential for heart function, kidney health, and muscle activity.

Why is the Potassium Test Important?

• High potassium levels (Hyperkalemia) may indicate kidney disease, dehydration, Addison’s disease, excessive potassium intake, or certain medications (e.g., ACE inhibitors, diuretics).
• Low potassium levels (Hypokalemia) may result from vomiting, diarrhea, diuretic use, malnutrition, or excessive sweating.
• Severe potassium imbalances can lead to irregular heartbeat, muscle weakness, paralysis, or life-threatening cardiac issues.

When is the Test Recommended?

• If a person experiences weakness, irregular heartbeat, muscle cramps, or high blood pressure.
• Individuals with kidney disease, heart problems, or those on diuretics may need regular potassium monitoring.
• Often included in electrolyte panels and kidney function tests (KFT/RFT).
