Immunohistochemistry (IHC) Biomarker Testing
Specialized protein antigen profiling on biopsy tissue to identify receptor status (ER/PR/HER2), lineage markers, and immunotherapy eligibility.
Clinical Overview & Diagnostic Rationale
Immunohistochemistry uses specific antibody-antigen reactions on tissue sections to evaluate cellular protein expression. In breast cancer, ER, PR, and HER2/neu IHC determines hormone receptor positivity and targeted drug selection. In lung and gastrointestinal cancers, PD-L1 IHC guides immunotherapy suitability.
Primary Indications & Clinical Scenarios
Requires paraffin tissue block (FFPE block) or freshly prepared unstained tissue slides from previous biopsy.
