in many of our experiments the way that we can be very certain that's the case is because we start by actually sequencing the tumor so let's say particularly for this initial problem we had of telling who is cured or not if you sequence those patients all have treatment they're all known to have cancer so we have a piece of their tumor we can sequence that and identify what mutations that tumor has compared to the patient's healthy cells let's say we find you know in a particular panel we might be using let's say we find 10 just for the sake of example so 10 mutations the patient's tumor has that the healthy cells don't we can then go look in the blood in the sequencing dataset we have for those molecules that carry the one of those 10 mutations and that turns out to be exquisitely specific and sensitive for the presence of the cancer
