Site-Specific Factor 15
HER2: Summary Result of Testing
Notes
**Note 1:** The summary of the results of the Immunohistochemistry (IHC), Fluorescent In Situ Hybridization (FISH), Chromogenic In Situ Hybridization (CISH), or other/unknown Human Epidermal Growth Factor Receptor 2 (HER2) test is recorded here. This variable is based on **Site-Specific Factors 9, 11, 13, and 14**. **Note 2:** If both an IHC and a gene-amplification test (FISH or CISH) are performed, record the result of the gene-amplification test in this field. However, if the gene-amplification test is given first and the result is borderline or equivocal and an IHC test is done to clarify these equivocal results, code the result of the IHC test. **Note 3:** If the results of one test are available, and it is known that a second test is performed but the results are not available, use code 997.Default
