Linda said "He said that to date, 1100 tests have come back as questionable because of the same type scenario and all the retests have cleared up the question by finding an error on the parents' tests or the retest on the pup came back as clear the second time"

This statement is NOT correct at all. The 1100 tests she is referring to are those where we have tested both parents and those results show NO cases where normal parents have produced carrier or affected offspring, No cases where normal to carrier breedings have produced test results indicating affected offspring and No cases where affected parents have produced normal offspring.

We have a report that is refreshed every day to flag inconsistent results and that starts a procedure to track down the reason. So far the few cases in that situation have proven to be caused by either misinterpretation of a result or mishandling of samples at some stage of collection and DNA extraction. In one case it was found that the dog in questions pedigree was incorrect.
