Hi Jennifer, I've been using the Avecon POCT kit for 2 years now, and confirming any positive results with a blood test at a later date. People have had problems with this test but it has to be done exactly to the instructions, which a lot of people seem to have trouble following and I believe this caused the inaccurate results. The main thing is the ferrets MUST not have any food for at least one hour before the mouth swabbing is done. We have used around 500 of these test kits and the failure rate seems to be no different than the usual blood test. Last year we had ferrets show positive to the Avecon test but negative to the POC test, this year those same ferrets were positive on both types of test so it looks like the Avecon test is picking up the virus well before the POC test. We dual tested 50 ferrets in Feb. to check the test kits were still working correctly.
