dobermom,
in the last several years i've seen claims that cornell university did a dna test on someones doberman. in each case where the owner pursued the business further it has turned out that cornell's test was NOT a dna test but an elisa assay.
the only lab licensed to to do the genetic test for vWD in north america is vet gen. the only other lab who was doing dna tests had to cease when they lost a court case to vet gen which was based on the fact that the test is protected by patent & the patent holder have the right to restrict testing to licensee's.
i'm not sure exactly what the wording is but i suspected some while ago that cornell (who does do elsa testing) has something in their paperwork which makes owners & vet clinics who send samples for testing to believe that they are getting a gene test & not a blood assay. there are a whole lot of vets who don't know there is a gene test & continue to rely on the elisa assay for accurate results.
as far as gene test errors go. it's is possible to have a testing error--sloppy lab techniques can account for them & in one case some bad reagents (test chemicals) caused errors but there have been no errors in quite a few years now.
i don't know who is still thinking that cornell's test is a gene test but i'd advise they check further into this.
