Fecal Dx antigen testing

Detect parasite infections even before eggs are present.

The most accurate, reliable diagnostic for shining a light on the most common and clinically relevant intestinal parasites in dogs and cats is Fecal Dx antigen testing. And soon, this test will detect Cystoisospora.
 

Upgrade to Fecal Dx

By testing for antigens rather than relying on the presence of eggs, you can detect earlier for hookworm, roundworm, whipworm, flea tapeworm, and—coming soon—Cystoisospora.

Earlier detection than fecal floatation1–5

Detect up to 5X more infections than fecal floatation alone1,4,6

  • Identify infections prior to eggs being shed.
  • Avoid false-negative results caused by intermittent shedding of eggs.
  • Detect worms even if eggs are not present in the fecal specimen.
