Yeah...anyone have any idea how many samples are fixed before the 1 hour mark? This combined with heterogeneity of the (partially sampled) tumor(s) itself really begs for a more comprehensive approach. Serum tests seem like a good first step. Now..do serum tests have similar time sensitive issues? Hmmm. How about temperature? Elephants form a line outside the room.
