I went to the Rational Therapeutics site and am pretty curious about it.

Relies on a "living" cell sample that has specific time constraints from sample to delivery. So..I'm thinking a very regimented biopsy setting would have to happen. Looks like it would cost $3,500 out of pocket. An extra $500 for individual consult. I filled out a contact form. Unfortunately, at one point it asked if patient could provide sample after 4 or so weeks without chemo. I hope this doesn't mean chemo invalidates sample.
