Frequently Asked Questions
Why is a digoxin serum test ordered?
It monitors drug levels in patients on digoxin for heart failure or atrial fibrillation, ensuring the dose stays within the therapeutic range and does not reach toxic levels.
What is the therapeutic range for digoxin?
The therapeutic range is 0.5–0.9 ng/mL for heart failure. Levels above 1.2 ng/mL are considered toxic and may cause nausea, visual disturbances, or cardiac arrhythmias.
When should the blood sample be drawn?
The sample should be drawn at least 6–8 hours after the last digoxin dose, when the drug has reached steady-state distribution, to ensure an accurate trough level.
Is fasting required for this test?
No, fasting is not required. Digoxin levels are not significantly affected by food intake.
What factors can affect digoxin levels?
Kidney impairment reduces digoxin clearance, raising levels. Drug interactions with amiodarone, verapamil, and spironolactone can also increase serum digoxin concentrations.
