Understanding your breast biopsy report

ER, PR, HER2 and Ki-67 — Test Cost in India

The ER, PR, HER2 and Ki-67 panel is run on your breast biopsy sample. The four results together determine your treatment plan. Cost depends on the type of laboratory and whether FISH is needed on top of the standard panel.

  • Four results, one sample — All four markers are usually tested from your existing biopsy tissue — no second procedure needed.
  • FISH is a separate charge — If HER2 comes back borderline (2+), FISH is ordered on top of the panel and billed separately.
  • Cost varies by lab type — Government and CGHS-empanelled labs charge substantially less than private chains.
  • Insurance usually covers IHC — Most health plans include the standard panel; FISH reimbursement varies across policies.

The ER, PR, HER2 and Ki-67 panel is run on your breast biopsy sample. All four results together shape your entire treatment plan — not just the cancer type, but the biological subtype. Costs vary by city and laboratory type. FISH for HER2, if your result is borderline, is priced separately and adds to the total.

Why are all four markers ordered together?

Your breast cancer's biological type — not just its size or stage — determines which treatments your oncologist will recommend. ER, PR, HER2 and Ki-67 are the four markers that establish that type from your biopsy tissue.

All four are run by immunohistochemistry (IHC) on slides prepared from your existing biopsy sample. No second biopsy is usually needed.

Each result tells a different part of the story. Interpreting one result in isolation, without the full panel and your stage, can mislead. Your oncologist will explain what the combination means for your specific case.

What does each marker measure?

ER — Oestrogen Receptor
Measures whether cancer cells carry receptors for oestrogen. Reported as positive or negative, usually with a percentage showing how many cells stained positive. Your oncologist will explain what the result means for your treatment plan.
PR — Progesterone Receptor
Measures sensitivity to progesterone. Interpreted alongside ER. A cancer can be positive for one and negative for the other — both results matter, and neither is read alone.
HER2 — Human Epidermal Growth Factor Receptor 2
Measures a protein on the surface of cancer cells. Reported as 0, 1+, 2+ or 3+. A borderline result of 2+ means FISH is ordered next to confirm the result before any conclusions are drawn.
Ki-67
Measures how rapidly cancer cells are dividing. A higher reading suggests faster growth. Your oncologist interprets this alongside the other three results — not in isolation — as part of the overall biological picture.

What should you sort out before and after the test?

  • Ask your insurer specifically whether IHC (immunohistochemistry) is covered — some policies require pre-authorisation before the sample is sent.
  • If FISH is also ordered, ask the laboratory for an itemised bill that separates it from the IHC panel for your insurance claim.
  • Confirm whether testing will be done in the hospital's own lab or at an external laboratory — costs and turnaround times can differ.
  • If you have CGHS, ECHS or a state health scheme, verify the laboratory is empanelled before the sample is sent, not after.
  • Keep printed copies of all four results — every new consultation and every insurance claim will ask for them.

How is the standard IHC panel different from FISH?

FeatureIHC Panel (ER, PR, HER2, Ki-67)FISH for HER2
What it measuresProtein expression on tumour surfaceHER2 gene copies in tumour DNA
When orderedRoutinely on first biopsy for all invasive breast cancersOnly when IHC HER2 result is 2+ (borderline)
Result formatPositive / Negative; percentage for ER and PRRatio and gene copy number
Typical turnaroundUsually within a few working daysUsually longer than IHC; confirm timing with your lab
Insurance coverageCovered by most standard health plansLess consistent; confirm with your insurer before the test

What else do families ask about cost and their report?

Does health insurance cover these tests?

Most standard health insurance plans in India cover IHC under pathology benefits, but the exact terms depend on your policy. Check whether pre-authorisation is needed and whether the lab must be a network provider. FISH is covered less consistently — some plans include it, others require a separate pre-authorisation or exclude it. Call your insurer before the test with the specific test names and ask for written confirmation of what is and is not covered.

Why does FISH cost more than the standard IHC panel?

IHC uses chemical staining on standard pathology slides and can be run in most equipped laboratories. FISH uses fluorescent probes to examine the HER2 gene directly, requires specialised equipment, and must be performed by a pathologist trained in molecular techniques. Because the process is more complex and the equipment less widely available, FISH is substantially more expensive and is not offered at all laboratories — in some cities the sample must be sent to a specialist centre.

Can I save money by using a government hospital lab?

Yes, substantially. Government medical college laboratories and CGHS-empanelled labs run these tests at publicly listed rates, which are considerably lower than private chain rates. The trade-off is usually turnaround time and, in some locations, availability of FISH. Ask your oncologist whether a government lab is appropriate for your case, and confirm that the reporting standards meet your treating team's requirements before the sample is sent.

My report is missing Ki-67 — does it matter?

It can. Ki-67 is part of the recommended panel under NCCN and ASCO guidelines because it gives your oncologist information about how fast the cancer is growing. If it is missing from your report, raise it at your next appointment. Additional staining can usually be run on the original biopsy tissue block without a repeat biopsy — but the treating team must make that request to the pathology laboratory, so do not delay mentioning it.

Did you know?

The combination of ER, PR and HER2 results alone defines at least four distinct molecular subtypes of breast cancer, each with a different treatment pathway.

ASCO and NCCN guidelines require all four markers on every invasive breast cancer before any treatment decisions are made — not as optional add-ons, but as a prerequisite.

Common questions

Frequently asked questions

What does the ER, PR, HER2 and Ki-67 panel cost in India?

Costs vary by city and laboratory type and change often enough that any figure here would quickly become unreliable. Government and CGHS-empanelled labs charge at publicly listed rates, which are considerably lower than private chain laboratories. The most reliable step is to call two or three labs in your city and ask for an itemised quote separating IHC from FISH. Also ask your oncologist whether the hospital's in-house laboratory can be used — in-house testing is often cheaper than sending the sample out.

Is FISH the same as the HER2 test, or is it a separate charge?

FISH is a separate test ordered on top of HER2 IHC, not a replacement for it. Your initial HER2 result will be reported as 0, 1+, 2+ or 3+. If it comes back as 2+ (borderline), FISH is ordered to look at the HER2 gene directly and reach a definitive answer. You will be charged for both tests in that situation. Not everyone needs FISH — it is only triggered by a borderline IHC result, so many patients pay only for the standard panel.

Will my health insurance pay for the ER, PR, HER2 and Ki-67 tests?

IHC is covered by most standard Indian health insurance under pathology or diagnostic benefits. Whether it requires pre-authorisation depends on your policy. FISH is covered less reliably — some plans include it, others exclude it or need a separate pre-authorisation. Do not assume FISH is covered because the IHC panel is. If a FISH claim is rejected, an oncologist's letter explaining the clinical necessity is often enough to support a successful appeal.

What does it mean if my HER2 result is 2+?

A HER2 result of 2+ means the test found an intermediate level of the protein — not clearly positive, not clearly negative. This is called equivocal or borderline, and it means the question needs a more precise answer before any treatment decision is made. FISH is the standard next step, looking at the HER2 gene directly. Your oncologist will not draw treatment conclusions from a 2+ result alone. Wait for the FISH result before drawing your own.

Do I need all four markers, or is ER and PR enough?

All four are part of the standard work-up for invasive breast cancer under ASCO, NCCN and ESMO guidelines. ER and PR together answer one question; HER2 answers a separate one; Ki-67 adds information about growth rate. Each result contributes something the others do not. If your report is missing one or more markers, tell your oncologist at the first appointment — additional staining can often be requested on the original biopsy block without a new procedure.

How long do the results take?

IHC results come back within a few working days from when the lab receives the prepared slides. Add time if the biopsy tissue needs processing first. FISH takes longer, and in some cities the sample must be sent to a specialist laboratory, which can extend the wait further. If your report is delayed, call the laboratory directly rather than waiting. The lab itself will have the most accurate update on where your sample is in the process.
