IHC (1)

What is the IHC1 test?

IHC1 refers to immunohistochemistry testing, typically for estrogen receptor (ER), progesterone receptor (PR), and HER2 markers in breast cancer diagnosis and prognosis.


Why is this test done?

It helps determine hormone receptor status in breast cancer patients, which influences treatment decisions and prognosis.


How is the test performed?

A tissue sample, usually from a biopsy, is stained with antibodies and examined under a microscope to detect the presence of hormone receptors.


What do the results mean?

Positive ER/PR results indicate that the tumor is likely to respond to hormonal therapy. HER2 positivity may guide targeted treatment options.


Are there any precautions or preparations required?

No patient preparation is needed, but proper tissue handling is essential for accurate results.
