Serum Digoxin Level

The Serum Digoxin Level Test is a blood test used to measure the concentration of digoxin in the bloodstream.

Digoxin is a medication commonly prescribed to manage certain heart conditions, including heart failure and specific heart rhythm disorders. This test helps healthcare professionals monitor medication levels, assess treatment response, and reduce the risk of digoxin toxicity.

What Does This Test Check?

The test measures the amount of digoxin present in the blood and may help with:

• Monitoring therapeutic digoxin levels.

• Assessing possible digoxin toxicity.

• Evaluating whether medication levels are within the recommended range.

• Supporting medication dose adjustments when clinically required.

• Monitoring patients receiving long-term digoxin treatment.

Sample Requirements

• Sample Type: Clot or Serum

• Sample Quantity: 2–3 ml

• Collection Instructions: Blood should be collected in an appropriate tube and processed according to laboratory requirements.

Patient Preparation

• Fasting is generally not required.

• Sample collection is usually recommended at least 6–8 hours after the last digoxin dose, often immediately before the next dose.

• Inform the laboratory about the current dose and time of the last medication intake.

• Do not stop or change medication without medical advice.

Important Information

• Digoxin levels should be interpreted alongside symptoms, kidney function, electrolyte levels, and treatment history.

• Blood collected too soon after a dose may show misleadingly elevated levels.

• Digoxin has a narrow therapeutic range, so accurate sample timing is important.

• Medication adjustments should only be made by the treating healthcare professional.

Reporting Time: To be confirmed by the laboratory.

Please confirm test availability and sample collection requirements with the laboratory before booking.
