Here's why:
* Heartworm tests are specific: A separate, specific test is needed to detect heartworm antibodies or antigens in the blood. This test is usually done by a veterinarian as part of a heartworm prevention program.
* Routine bloodwork focuses on other issues: Routine bloodwork is designed to check for overall health, including kidney and liver function, red and white blood cell counts, and electrolytes. These tests are not sensitive enough to detect heartworms.
Important note: It's crucial to have your dog tested for heartworms regularly, even if they are on preventative medication. Heartworm prevention is not 100% effective, and false negatives can occur.
Recommendations:
* Talk to your veterinarian about the frequency of heartworm testing for your dog based on their individual risk factors.
* Follow your veterinarian's recommendations for preventative medication, and be sure to administer it as directed.
