Could someone please help me understand the numbers I keep reading here related to HER-2 positivity? I think I've read things like "HER-2, 9.6" or "HER2+++" and so on.
I assume the +++ must be the IHC scale, where 1 is negative, 2 questionable and 3 positive. But I thought I saw one HER-2++++.
The FISH part of my path report reads:
"nuc ish 17q11.2-q12 (HER-2 amp+). The ratio of HER-2 to CEP17 is greater than 4.0."
I have forgotten to ask the docs for over a year, so I hope someone can explain or perhaps direct me somewhere I can get this information.
