Infectious disease screeningDogsA few drops of blood
Heartworm & Tick-Borne Disease (4Dx)
One blood test screening for heartworm plus three tick-borne diseases.
What it measures
- • Heartworm antigen (protein from the parasite)
- • Antibodies to Lyme, Ehrlichia, and Anaplasma
What results can show
- ✓ A positive heartworm result indicates an active infection
- ✓ Recommended annually in most regions
Honest limitations
For the tick-borne diseases the test detects antibodies, so a positive means exposure — not necessarily an active infection. Those results need your vet’s interpretation and sometimes follow-up testing.
What we collect
Positive/negative results for each of the four targets.
