IHC ANALYSIS

What is IHC analysis?

IHC or immunohistochemistry is a special dye treatment applied to lung and breast cancer biopsies. IHC is used to show whether biopsies have HER2 receptors or hormone receptors. This test measures the amount of HER2 receptor protein and scores with values between 0-3 +. If the score is 0-1 + 'HER2 negative'; If the score is 2+ 'borderline'; Score 3+ means 'HER2 positive'.
