her2serum test results HELP

[Princesswaffle]

Thank you so much for the link! I very much appreciate it. I know that the test is a prognostic tool, but wanted to see if anyone has had a test that may have shown an elevated level, that could have been a reading error on the lab part or an error in the handling of the tube, that after retesting was back in the normal range. I am somewhat concerned since, but all my other markers and scans have shown NED, so I am not sure what else there is I can do even if levels continue to rise and it is not a lab mistake. At this point my doctor is ecstatic at my progress and feels that since I am monitored by blood work every three weeks that there is no cause for concern and she is leaning towards an error. I want to agree, but I also want to hear other people who have had similar experiences.

Thank you!
