Digoxin

What is Digoxin Testing?

A digoxin test is a type of blood test purposed to find the level of the concentration of medicine in your blood. Digoxin is a medicine used for the treatment of cardiac problems and irregular heartbeats.

When an individual has heart failure, including congestive heart failure (CHF), he/she starts feeling some symptoms like swelling, fatigue, and breathing problem. And all these symptoms happen to an individual because his/her is less effective in circulating blood in the body. In that condition, the blood starts accumulating in the liver, feet, hands, legs, and lungs. 

Digoxin relates to the cardiac glycoside group and it is prescribed to the patients with cardiac problems. Your doctor may order for the digoxin testing to check whether you are taking an optimal amount of digoxin. The test helps them to know the level of digoxin in your blood as it may cause some other serious problems if you are taking too much or very little of the medicine.

Digoxin is a potentially a toxic medicine that can affect you adversely if you don’t take it as suggested. The incorrect dose of digoxin may lead to some other health conditions. Therefore, doctors keep performing the digoxin testing to monitor the amount of it in your blood when you are this medication.

Based on your symptoms, your doctor may order for the test several times. In case of the low level of digoxin in your blood, you may experience the following symptoms:

How to prepare for the test?
