Hmmm.... nice. DNA-based genetic diagnostics are still relatively
nascent, though. (There are enough good tests that it's a viable
business, but for cancer diagnostics it's not really the in thing.)
The bulk of oncodiagnostics these days is apparently done via
"cytogenetics," a much more involved process. (Ironically, though far
more labor intensive, this is less expensive.) A lab gets tissue or
other cellular products, cultures it, then harvests / fixes / cuts /
scopes it to produce a karyotype. The diagnostic is performed by
looking at the chromosomes directly rather than DNA sequences. (E.g.,
chromosome #3 is deleted, #8 is "inverted", #15 is duplicated, #21 is
truncated, etc. etc. --- this particular set of changes correlates to
pathology X, Y, or Z...)
Not sure what benefit having an offshore cytogenetics lab would be,
though. 'Course, I'm just trying to figure out how I can leverage my
POSSLQ's particular expertise here. :-)
