Mr. Denis Duggan:

My understanding is that the move was made about ten or 12 years ago. I do not know the reasons for it but we can go away and review the archive to see what the rationale was. The context is it is the vet who takes the hair sample. We traditionally always had a 4% to 5% failure rate, where there was not enough hair follicle. The issue is not the hair in itself; it is the root follicle-----
