    I don't think it is "mislabeled" so much as mis-queued. IE it correctly read labels 1, 2, 3, 4, 5. But when they were queued, they went in as 5, 4, 3, 2, 1 or something else equally strange.

    You wrote likely relatives, and not that you are sure of that.

    Two mislabelled vials do not seem to be likely, so I understand FTDNA actions.


    On the other hand, I tend to use scientific approach, and I would use YSEQ to test for the SNP that defines the major haplogroup you are expecting, since F is ancestral to many popular European haplogroups. That would be a very cheap confirmation or disapproval of your hypothesis (and FTDNA lab results).

    P.S.
    I might have thought differently, but nowadays I add Family Finder when ordering Y DNA and mtDNA tests. And I have asked my family to retroactively add Family Finder to all the older kits.

    Were you in test batch 925 by any chance? A kit I was tracking had erroneous STR results in that batch which probably only was caught as quickly as it was due to a BigY test also being underway which didn't agree with the initial STR results. In that case they went from E-M35 to R-Z280+ which is "just a tiny bit of a difference." Not reassuring when errors occur, but as it probably coincided with the transition from Y500 to Y700, I could imagine a few lab miscues slipped through.

    Failed YDNA test -- no new sample

    To try to get past a roadblock in research, I have paid for a couple of tests of likely relatives in Switzerland.

    The last one returned ridiculous results (Haplogroup "F"), and only enough "matches" to count on one hand.

    FTDNA has chosen to simply re-run the original sample, with a 6-8 week wait time. This doesn't make sense: The lab inaccurately processed the first sample, for unknown reasons. A new sample should be ordered.

    I'm disappointed, and am considering other services for future tests.

    In genetic genealogy, accuracy is all.
