What kind of tests do veterinarians to check for heartworms in pets?

There are two main tests that veterinarians use to check for heartworms in pets:

1. Blood Test: This is a simple blood test that can detect the presence of heartworm antigens in the bloodstream. This is the most common test used to diagnose heartworms in canines and felines.

2. Antigen Test: This test is also used to detect the presence of heartworm antigens, but it is done using a quick, in-clinic test that provides results within minutes.

Additionally, veterinarians may recommend the following diagnostic tests:

3. Echocardiogram: This is an ultrasound examination used to examine the structure of the heart and to detect signs of a heartworm infection such as enlarged chambers, valve abnormalities, and blood clots.

4. X-ray: An x-ray of the chest can reveal the presence of enlarged arteries, an indication of heartworm disease.

5. Electrocardiogram: This test measures the electrical activity of the heart and can detect changes that may indicate a heartworm infection.

It's important to note that the veterinarian may recommend additional tests based on the pet's individual situation and findings from the initial tests. Early detection and treatment of heartworms are essential for the long-term health and well-being of your pet.
