I have seen incorrect test results more than once
Friend had a stallion who she tested came back negative & she advertised him as such.I thought no way he is negative he was classic frame in his markings.It was suggested she should retest but she insisted he was negative.Sang a different tune though when he produced a leathal white foal the following season
