post Herceptin her2 blood levels???

My understanding of Her2 status was not from blood test. It is from the actual tumor tissue. You wanted to know if you are still her2, chances are "yes", to my impression.(I was her2 3+ 5 years ago, and when I had mets to lung, biopcy showed her2 +3 again after 5 years!)The only thing you need to know from the blood test rutinely is the tumor marker which will indicate any mets. When you have mets, they can do biopcy to test her2 or ER/PR status. Since you are NED, you should ch if you need any hormonetreatment to maintain it and do a lot exercise, keep good diet, most important relax and get rid of stress!Hope this is the right answer you expectted!
