Can IHC results be obtained through blood work?
No, IHC (immunohistochemistry) testing cannot be done through blood work. IHC requires a tissue sample from a biopsy to examine the actual cancer cells.
The IHC test is performed on biopsied breast tissue that's attached to a glass slide. A chemical solution with special antibodies is added to see if cancer cells contain specific proteins like HER2, estrogen receptors, or progesterone receptors.
Blood work serves different purposes during breast cancer care, such as:
- Checking blood cell counts
- Testing liver and kidney function
- Measuring tumor markers
If you need IHC testing, your doctor will need to perform a biopsy to collect tissue samples. This is the only way to accurately determine your HER2 status and hormone receptor status, which are crucial for choosing the right treatment plan.
