Fecal Dx antigen testing
Detect parasite infections even before eggs are present
By testing for antigens rather than relying on the presence of eggs, you can detect early and accurately for hookworm, roundworm, whipworm, and flea tapeworm.

Earlier detection than fecal flotation1–5

Detect up to 5X more infections than fecal flotation alone1,4,6
Find what the microscope misses with Fecal Dx antigen testing2–5
- 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 sample.

Help protect pets and families like never before
Detecting infections sooner helps you treat effectively, reducing the risk of infection to other pets and family members.7
