Usually if there is a problem, you hear very quickly. It's less of a priority when there is nothing of concern. So, take it as good news. If you haven't heard by Thursday of THIS week, call them. They had trouble getting ahold of me once and so I got no results for over a week but it was an issue of not having the right number. But you should heard any day or call them by Thursday. Try not to worry. Again, they usually contact you fairly quickly if there is an issue. good luck
