Use the following algorithm to guide next steps based on your patient’s Fecal Dx antigen testing results.1

Antigen-negative results
What to do next?
Treat with appropriate dewormer or use monthly parasite control product effective for this parasite
Communicate the success of current preventive measures Review possible risks and reinforce year-round protection
Review risk factors and proper disposal of feces
Retesting a healthy dog who is on a broad-spectrum monthly control product is not necessary If a follow-up test is preferred, retest by antigen testing and fecal flotation 7–10 days after deworming
CAPC recommendations: Fecal examinations at least 2 times per year
Administer year-round, broad-spectrum parasite control with efficacy against heartworm, intestinal parasites, fleas, and ticks

Testing sick dogs

Testing recommendations vary based on the duration and severity of diarrhea and the health and dietary habits of the dog or dogs affected.
