I was not sure what Julie was referring to when she mentioned the "regular one" vs the Bayer serum test for Her2+. I thought the only other test was the tissue sampe. Are there 2 different blood tests?
I have a second question. If one was Her2+ and treated with herceptin, would a low test result mean that they:
1) no longer were Her2+ ?
OR
2) did not have metastases?
