Round one of testing...all 7 ferrets tested with ELISA blood test. All 7 came back positive. Retested 3 for confirmation with United CEP, all 3 tested negative. The blood was drawn for the different tests a week apart by my vet. No vax were given during that time and only one ferret is on meds (pred). I emailed Dr. Stephon and asked for an explanation as to the discrepancy between his lab and United. To date, I have had no reply (has been nearly 3 weeks now). Since Dr. Stephon has failed to give me any explanation, I will most likely have Dr. Stevenson test 3 or 4 of my kids and see how those results turn out. Right now, I honestly don't know anymore than I did $200 ago. Tea` [Posted in FML issue 3730]
