There is much confusion about the results of IHC and FISH test results. They both measure different segments of the HER2/neu gene so there is no direct correlation.

The results of the IHC test are: 0,1,2,3 and 3+++

The results of the FISH test is a ratio of Chromosone 17 to HER2 genes and there are only two scores: positive or negative.

For an explaination of both tests go to:
