Why This Biomarker Matters

Proper digoxin levels are critical for heart disease treatment; too little is ineffective, too much causes dangerous side effects requiring dose adjustment.

Understanding Your Results

Normal Range

0.6 – 2 nmol/L

Overview

This test measures the level of digoxin in your blood, a cardiac glycoside medication used to treat heart failure and certain arrhythmias. Digoxin has a narrow therapeutic window—the difference between an effective dose and a toxic dose is small. Monitoring blood levels ensures the medication is working at the right dose without causing toxicity, which can cause nausea, arrhythmias, and other serious side effects. Regular monitoring is essential for patients on long-term digoxin therapy.
