has anyone had this?

[grandma2]

saw onc today. of course we discussed my inability to tolerate xeloda. last attempt was 2000mg daily. she wants me to have the 5 FU/capecitabine toxicity test. hutchick suggested this and i asked about it. my confusion came when the office manager was filling out the tons of paperwork...she kept repeating that this is a full genetic test and everything about my dna would be analyzed. this was not my understand and quite frankly i never wanted dna testing. i've gone to the website and according to this the test is just for analysis of the DPYD and TYMS genes. so should i assume that this woman just did not know what she was talking about? wondering also if medicare will pay for it. thanks, gm
