What causes Potassium 7.0 mEq/L?

Advanced kidney failure Severe acidosis or tissue breakdown Acute kidney injury with hyperkalemia

What should I do if my Potassium is 7.0?

Call emergency services / go to the ER now IV calcium to protect the heart, then insulin-glucose to shift potassium Dialysis is usually needed and is the fastest reliable fix

Potassium — Critical

Potassium 7.0 mEq/L: What It Means

Classification: Critical

Potassium 7.0 is a life-threatening emergency — imminent risk of cardiac arrest from arrhythmia. This requires immediate emergency treatment.

What can cause this?

Advanced kidney failure
Severe acidosis or tissue breakdown
Acute kidney injury with hyperkalemia

About the Potassium test

Potassium is the main intracellular electrolyte. The kidneys control its balance â€” CKD reduces potassium excretion, so levels rise as kidney function falls.

Standard blood test. Fist clenching or hemolysis during the draw can falsely raise it (ask for a repeat if in doubt).

Reference: Normal range per major laboratories; hyperkalemia thresholds per KDIGO • Normal range: 3.5-5.0 mEq/L

Other Potassium Values

3.2 mEq/L 3.4 mEq/L 3.5 mEq/L 5.0 mEq/L 5.2 mEq/L 5.5 mEq/L 5.8 mEq/L 6.0 mEq/L 6.5 mEq/L
