Heartworm infections may be occult for a number of reasons: A heartworm test is to check for the evidence of the parasite Dirofilaria immitis, more commonly known as heartworm, in your dog's bloodstream.
The test should be performed on any dog showing signs of heartworm disease, e.g. exercise intolerance, coughing, loss of appetite, weight loss, labored breathing, or heart disease. Antigens for the heartworm cannot be detected until seven months after initial infection. For this reason, testing animals less than 7 months of age is not indicated. Annual re-testing is recommended for dogs not receiving heartworm preventative year round.
