Faecal Dx antigen testing
Detects common and prevalent parasites earlier—even when there are no eggs present.1-5
That's good news for you. Bad news for parasites.
Unlike other faecal testing methods, Faecal Dx antigen testing doesn’t rely on the presence of eggs for an accurate diagnosis. Instead, it detects parasites by their antigen protein. If there are parasites, there will be antigen. Even in prepatent or single-sex infections.

By testing for antigens rather than relying on the presence of eggs, you can detect earlier and more accurately for hookworm, roundworm, whipworm and – coming soon – flea tapeworm.1,2
Earlier detection than faecal flotation1–5
Detect up to 5X more infections than faecal flotation alone1,4,6
Find what the microscope misses with Faecal 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 faecal sample.
