On split-specimen tests, only bottle A gets tested. Bottle B gets stored away and only gets tested if the donor decides to challenge the test results of bottle A.

And if this was a split-specimen test, you would understand that it is one because you are required to enter your initials on both bottle A and B. The collector must also perform the actual split in your view.
