Hello,
I have had two IHC tests. The first test my doctor described as having Her2 traces and asked for a the second which was Her2 3+.
In order to qualfiy for a clinical trial a FISH test had to be done and it came back negative.
From what I have read this rarely happens with a IHC 3+ result.
I would be very grateful if you could advise as to what my Her2 status actually is.
Regards Maggiec
