Common questions about heartworm test costs
How much does a heartworm test cost?
Heartworm tests typically cost $10 to $80 depending on the provider and test type. Retail walk-in clinics generally charge $35 to $48 without an exam fee, nonprofit clinics may offer tests for $20 to $35, and private veterinary offices may charge $45 to $80 which often includes an exam fee. Verify pricing before visiting.
Can I get a heartworm test at Petco or PetSmart without an exam?
Based on publicly available information, retail clinics at Petco (Vetco) and PetSmart (ShotVet) typically offer walk-in heartworm testing without requiring a full veterinary exam. This can make the test more affordable compared to private veterinary offices that may include an exam fee. Availability varies by location.
How often does my dog need a heartworm test?
Annual heartworm testing is generally recommended for all dogs, even those on year-round prevention medication. Testing is typically required before starting or refilling heartworm prevention prescriptions. Your veterinarian may recommend more frequent testing in certain circumstances. Consult your veterinarian for guidance specific to your dog.
What's the difference between a heartworm test and a 4DX test?
A basic heartworm test screens only for heartworm disease. A 4DX test (or similar combo test) screens for heartworm plus tick-borne diseases including Lyme disease, Ehrlichiosis, and Anaplasmosis. The 4DX test typically costs more but provides a broader health screening. Ask your provider which test option is available.
