It is advised to get your vet to check for heartworm symptoms that may not be outwardly apparent. Why? Because by the time your dog starts to exhibit obvious symptoms of heartworm such as lethargy or intolerance to exercise, the heartworm infestation is already advanced and your dog may be beyond easy help.
Fortunately, your veterinarian can perform a few simple tests that detect internal symptoms of heartworm. Heartworm treatment for dogs is a dangerous process; the earlier you are able to detect an infestation, the better.
One of the easiest and most effective ways your veterinarian will detect the presence of heartworm in your dog is to use an ELISA (Enzyme Linked Immunosorbant Assay) test. This test will detect heartworm antigens if present in your dog’s blood sample. Antigens are produced by the adult heartworm, and is a reasonably accurate way to detect an infestation.
A microfilariae test is conducted by a veterinarian analysing your dog’s blood sample through a microscope, where the presence of these infant heartworms are visually detected. This test isn’t completely accurate, as there are a number of factors that may lead to lack of microfilariae even if adult worms are present. There is also risk that a false positive is made in error, when a vet may mistake the microfilariae of harmless parasites to be that of heartworms.
There are other ways to detect otherwise invisible symptoms of heartworm. Your vet may use an ECG and detect a disturbance in your dog’s heart rhythm. Or, a chest X-ray may reveal an enlarged heart or swollen pulmonary arteries, indicating severe infestation.
All of these symptoms may be detected by your vet before your dog exhibits any obvious outward symptoms of illness. This may particularly be the case if your dog leads a relaxed lifestyle. Get your vet to check for heartworm symptoms today. It may just save your dog’s life.
