Fecal Dx antigen testing.

For early, accurate detection of the most common, clinically relevant intestinal parasites—even before eggs are present.1–3

Accurately screen for the most common and clinically relevant intestinal parasites.

Fecal Dx antigen testing detects parasite-specific antigens rather than relying on the presence and detection of eggs. More infections can be caught earlier, even in pets that seem perfectly healthy.1-3

The Companion Animal Parasite Council (CAPC) agrees that antigen testing is an advanced diagnostic method, and they don’t recommend passive flotation, where parasite infections can be missed, leading to missed diagnoses.4

The future of parasites is 
they have no future.

It’s true. Fecal antigen testing is the future of parasite screening as we know it, catching up to 2x more infections. And now, after a retrospective study of nearly 900,000 cases that compared fecal antigen testing to flotation, we have the data to prove it.5


Detect up to 2x more infections earlier than fecal flotation.5†

†Cumulative antigen positivity for 6 antigens/any O&P positive = 1.9x more.
Cumulative antigen positivity for 6 antigens/O&P positives for those same parasites = 2.3x more.
