WebFeb 27, 2024 · FISH testing also measures the amount of HER2 within your breast cancer cells. However, while IHC tests for protein overexpression (high levels of the HER2 protein), FISH tests for HER2 gene amplification (lots of copies of the HER2 gene). FISH results may be more accurate than IHC, but FISH can cost more and take longer to process. WebNotably, the guideline refined optimal testing algorithms for positive, equivocal, negative, and indeterminate HER2 results. For example, the 2007 guideline defined HER2 positivity as either IHC 3+ or FISH with a HER2/CEP17 ratio >2.2 or average HER2 gene copy number >6 signals/nucleus for test systems without an internal control probe.
