The 4Dx Test is a blood test for dogs that screens for Heartworm disease and 3 tick-borne diseases (Lyme, Ehrlichia and Anaplasma).

  • A positive Heartworm test requires immediate treatment. Heartworm test results are only valid on dogs six months of age or older.
  • A positive test for tick-borne disease may or may not be treated, depending on individual circumstances to be discussed with your veterinarian. If a dog tests positive for Lyme, we recommend administering the Lyme vaccine to protect against future infections. Please read our Lyme Disease Update for more details.
