Frequently Asked Questions
Why is ER PgR HER2 testing done on breast tissue?
These biomarkers determine whether the tumor grows in response to hormones (ER/PgR) or has HER2 protein overexpression, guiding targeted treatment decisions.
What do positive ER and PgR results mean?
Positive hormone receptors indicate the cancer may respond to endocrine therapies like tamoxifen or aromatase inhibitors, improving treatment options.
What does HER2 3+ vs 2+ mean?
HER2 3+ is definitively positive and qualifies for targeted therapy like trastuzumab. HER2 2+ is equivocal and requires FISH testing for confirmation.
How long does the report take?
IHC biomarker results are typically available within 2 to 3 working days from receipt of the FFPE tissue block.
Can I get the report online?
Yes, verified PDF reports are available within 48 hours via www.drpatholab.in or through WhatsApp and email.
