Found at my Genographic page, the message in bold letters is newly added.
Your sample needs additional testing. In some cases, the standard testing procedures do not permit the accurate determination of a haplogroup, so we perform additional tests. This test is referred to as a SNP test. This is not uncommon, but will delay the posting of your results by two to three weeks. You do not need to take any action at this time.
Please be aware that in some cases a simple SNP test may be inconclusive, which could result in additional delays of several weeks as we continue to test your sample.
If we find that there is a problem at any point during the processing of your sample, you will receive an updated message when you log in to check your status.
