The short answer
A letter says my genetic result has changed. What do I do first?
Find out which way the result moved, then book a conversation with the counsellor or doctor who ordered the test. Do not start, stop or cancel anything on the letter alone. Most letters bring good news, because the most common change is an uncertain result being settled as harmless.
Three things to find on the letter
Look for the old classification, the new classification and the date of the change. Check that your name, date of birth and sample number match your original report. The letter may come by post, by email or as a message forwarded from the lab, and it is often written in technical English.
Why you should not act on it alone
A reclassification letter is written for a doctor to interpret. The same new classification can mean different things depending on your own history, your family tree and any treatment you are already having. What your specific variant means is a question for the counsellor who ordered the test.
Keep the letter with your original report. The two belong together from now on.Reading the change
What is the letter most likely telling me?
Almost every reclassification letter falls into one of these four groups. Each one leads somewhere different.
Uncertain, now harmless
The most common letter. A variant of uncertain significance, or VUS, has been settled as benign or likely benign. Your care now follows your family history alone, and relatives need no test for it.
Uncertain, now a real fault
Less common. The variant is now pathogenic or likely pathogenic, meaning disease-causing. This letter needs a prompt appointment, because screening may change and blood relatives can be offered testing.
Bring to the appointment
- The letter and your original report
- A list of relatives on both sides
- Any scans or treatment since the test
A fault, now downgraded
Rare. A variant once called pathogenic is now thought harmless or uncertain. Past decisions, and any relatives tested for it, need to be looked at again with your doctor. Do not undo anything on your own.
A correction, not a change
Some letters only update how the variant is written or which gene name is used. The meaning is the same. File it with the original so future doctors see the current wording.
Not sure whether this applies to you?
Ask an oncologistIn the first fortnight
What should I do, step by step?
Confirm the letter is yours
Match the name, date of birth, lab name and sample number against your original report. Mistakes are uncommon, but worth ruling out.
Contact whoever ordered the test
That is usually your oncologist or genetic counsellor. If they have moved on, the hospital that ordered the test can direct you to someone who can read it.
Book a counselling appointment
An upgrade needs a proper conversation, not a quick phone call. Ask for one in Telugu if that is easier for you and your family.
Wait before telling the whole family
Share it once you understand it. The counsellor can help you decide who needs to know first and can prepare a family letter.
Update your own records
Keep both documents together, and tell every doctor who treats you that the classification has changed.
On the letter
The words you will meet, in plain language
- Reclassified
- The lab has changed what it says your variant means. The variant in your DNA has not changed.
- Previous classification
- What your original report said. The letter should show this beside the new one so you can compare them.
- Amended report
- A reissued report carrying the new classification. It replaces the meaning of the old report, not the record of it.
- Evidence summary
- A short paragraph explaining why the lab changed its view, such as new family studies or data from other labs.
- Ordering clinician
- The doctor or counsellor who requested your test. Labs usually send updates to this person first.
- Cascade testing
- Offering blood relatives a test for one known family variant, one branch of the family at a time.

Being straight with you
What this page cannot tell you
It cannot tell you what your letter means for you. The same change can matter a great deal to one person and very little to another, depending on their history and treatment. Only someone who has your report, your letter and your family tree in front of them can answer that properly.
It cannot say whether the change is final
Classifications can be reviewed again as evidence keeps growing. A second change is uncommon, but a reclassified result is still the lab's best current judgement, not a last word. Ask your counsellor how any future update would reach you.
Who this does not apply to
If you have not had a germline test, meaning a blood or saliva test for inherited faults, this page is not about you. Changes to tumour test results are a separate subject, covered on the targeted therapy pages. And if your letter only corrects wording, there is usually nothing to act on.
If the letter reached a relative instead of you, the steps are the same. Take it to the doctor who ordered the test.Commonly believed
Four things people assume when the letter arrives
"A letter from the lab must mean bad news."
Most reclassification letters settle an uncertain result as harmless. Many people feel alarmed opening the envelope and relieved once someone explains it.
"The first report was a mistake, so I cannot trust any of it."
The reading of your DNA was almost certainly right. The knowledge used to interpret it has moved on. That is why labs review old results in the first place.
"If it has been upgraded, I should book surgery straight away."
An upgraded result opens a discussion. Screening, medicines and preventive surgery are options to weigh with your doctor over time. Nothing needs deciding the week the letter arrives.
"My relatives do not need to hear about a downgrade."
They do if they were tested for the variant or changed their screening because of it. A downgrade can lift worry and unnecessary tests from several people.
Questions we are asked
Common questions about reclassification letters
Why did the letter come to me and not my doctor?
Labs differ. Some write to the ordering doctor only, some to the patient as well, and some send a copy to both. If yours came to you directly, forward it to the doctor who ordered the test and ask for an appointment to go through it together.
The doctor who ordered my test has left. Who reads it now?
Contact the hospital or clinic where the test was ordered and ask to be seen by their oncology or genetics team. Any qualified genetic counsellor or clinical geneticist can read the letter alongside your original report. Bring both documents to that appointment.
My result was upgraded. Do my children need testing now?
Adult children can usually be offered a test for that exact variant. For faults that raise risk only in adult life, testing of young children normally waits until they can decide for themselves. Your counsellor will tell you which situation your family is in.
My result was downgraded after I had preventive surgery. What now?
This is rare and very hard to take in. Ask for a joint appointment with your surgeon and the doctor who ordered the test. They will look at whether your family history still supported the decision and what follow-up you need. Support is available for this situation.
Does a reclassification letter cost anything?
Receiving the letter does not commit you to any cost. A counselling appointment to discuss it, a review you request yourself, and any testing offered to relatives may each carry a fee. Ask about charges when you book so that nothing comes as a surprise.
Should I tell my insurer about the change?
India has no dedicated law on genetic discrimination in insurance, and disclosure rules depend on your policy wording. This is worth raising with your counsellor and reading your policy carefully. Do not guess at an answer from websites written for other countries.
Can the classification change again?
It can, though a second change is uncommon. Each classification is the best judgement on the evidence available at the time. Keep both reports safe and keep your contact details current with the lab and hospital, so any later update can reach you.
How do I explain the letter to my parents?
Start with what it means for them in one sentence, not the gene name. Ask the counsellor for a short family letter, in Telugu if that helps. Offer the counsellor's contact so they can ask their own questions rather than relying on your retelling.
