Absolutely, this happened to me with my first litter, born shortly before the dna test was available. I bred a clear via ELISA test bitch to a clear by ELISA test stud dog. Five months later the dna test came on the market, and we found out some of the resulting puppies were affected via dna.
There's more of a problem with the ELISA test than just an overlap of categories. The results can also be affected by a wide variety of external factors-hormones, stress level, etc. The results aren't worth the paper they're printed on.
As Dobebug said, Vetgen is the ONLY entity who can legally offer dna tests for vWD. This is because they hold the patent on the actual genetic location of the vWD mutation.
