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.
