Actually, although the panels were obviously not selected at random,
they were also not selected with foreknowledge of the results of
Sharon's testing, or yours or mine, for that matter. Thus, as long
as we can assume mutations occur independently, the selection
effectively *is* random because it's the mutations that do the
"selecting" as far as the test results are concerned.
