Genetic test kits sold in India: how to judge one before you pay | CION Cancer Clinics
A genetic test kit is worth buying only if it names every gene it reads, is run in an accredited laboratory, and comes with a counsellor before and after the result. Many kits sold online in India miss at least one of these. This page gives you the questions to ask the seller, the warning signs to look for, and who does not need a kit at all. At CION Cancer Clinics in Hyderabad, our oncologists review your family history with you and guide you to the right genetic counselling and testing.

The short answer
How can you tell whether a genetic test kit is worth buying?
A kit worth paying for names every gene it reads, is run in an accredited laboratory, and comes with a genetic counsellor before and after the result. It also has a doctor behind it who will act on what it finds. Many kits advertised online in India meet one or two of these, and fewer meet all four.
Why the checking falls on you
Tests sold straight to the public face lighter oversight than tests a doctor orders. Advertisements often lead with a discount or a promise of peace of mind, and rarely say what the test cannot see. A few questions asked before you pay will tell you far more than the price or the packaging.
Why it matters more here
India has no dedicated law protecting people from genetic discrimination in insurance or employment. A result, once on paper, can travel through a family WhatsApp group in minutes and come up during marriage talks. A poorly explained report can cause real harm before anyone qualified has looked at it.
An ancestry or wellness gene report is not a cancer risk test, however it is marketed.Four things to check
What should a good kit show you before you pay?
If the seller cannot answer these four points clearly, in writing, treat that as your answer.
The full gene list
Every gene read should be named, along with the kinds of change looked for in each. Phrases like "comprehensive cancer screen" with no list behind them tell you nothing about what was left out.
An accredited laboratory
Ask where the sample is actually tested. In India, look for NABL accreditation of the testing laboratory for genetic work, not just of a collection centre. Samples sent abroad should go to a laboratory with equivalent accreditation in that country.
Counselling on both sides of the test
A qualified genetic counsellor should talk to you before the sample is taken and again when the result arrives. A phone call from a sales executive is not counselling.
Good counselling covers
- Whether you need the test at all
- Who in the family should go first
- What each possible result would mean
A plan for what happens next
Ask who explains a positive result, who arranges screening, and how relatives can be tested for the same fault. A kit that ends at a PDF report leaves the hardest part to you.
Not sure whether this applies to you?
Ask an oncologistBefore you pay
What questions should you ask the seller?
-
Who is this test meant for?
A kit suited to someone already diagnosed may not suit a healthy relative, and the reverse. If the answer is "everyone", the kit has not been designed around a real clinical question.
-
Does it find missing or extra chunks of genes?
Some inherited faults are large deletions or duplications that ordinary reading can miss. Ask whether the kit looks for these, and by what method.
-
How are findings checked and classified?
A reliable laboratory confirms important findings and classifies variants using published international standards. Ask which standards it follows and how an uncertain result is reported.
-
What happens to my sample and my data?
Ask whether your DNA is stored, shared with research partners or sold on, and how you can ask for it to be destroyed. Get the answer in writing.
-
Will I hear if my result changes?
Classifications are revised as evidence grows. Ask whether the laboratory will contact you or your doctor if a finding in your report is ever reclassified.
On the box and the website
What do the words on a kit's page really mean?
- NABL accredited
- The laboratory has been assessed against a recognised quality standard by India's national accreditation board. Check that the scope covers genetic testing.
- Clinical grade
- A marketing phrase with no fixed meaning. It only counts if an accredited laboratory and a counsellor stand behind it.
- Germline
- Inherited, present in every cell from birth. This is what a cancer risk kit should be testing.
- Variant of uncertain significance
- A change the laboratory cannot yet call harmful or harmless. It should not drive any medical decision.
- Confirmation testing
- A second, separate method used to check an important finding before it is reported.
- Reanalysis
- Reading your existing data again later, as knowledge improves. Some laboratories offer this and some do not.

Being straight with you
What this page cannot tell you
It cannot tell you whether a particular brand is good. We do not rate or recommend commercial kits by name, and quality can change when a company switches laboratories. The four checks above apply to any kit, from any seller.
It cannot read a kit result you already have
If you have already bought a kit and have a report, do not act on it alone. What your specific variant means is a question for a qualified genetic counsellor or clinical geneticist. Some kit results need to be confirmed by a second test before any decision is made.
Who this does not apply to
Most people do not need a genetic test for cancer risk at all. If your family has one relative diagnosed at an older age and no pattern of young or rare cancers, a kit is unlikely to tell you anything useful. If a relative already carries a known fault, you need a test for that one change, arranged through a counsellor.
If a relative has cancer now, their oncologist is usually the best person to arrange testing, starting with them.Commonly believed
Four things buyers assume, and what is actually true
"A clear result from a kit means I am safe."
A clear result only covers the genes and the kinds of change the kit looked for. Your family history still counts, and it still decides when your screening should start.
"A costlier kit must be more accurate."
Price reflects the number of genes, the brand and the marketing as much as quality. A smaller, well-chosen panel from an accredited laboratory can be the better test.
"If the kit found something, I should plan surgery."
No medical decision should rest on an unconfirmed kit result read without a counsellor. Findings are checked first, and every option, including closer screening, is discussed before anything is decided.
"Doing it privately at home keeps the result private."
Your data sits with the company that sold the kit. Read how it is stored and shared. A test ordered through your own doctor keeps the result inside your medical record.
Questions we are asked
Common questions about genetic test kits
Are home genetic test kits legal in India?
They are sold openly, and oversight of tests sold straight to the public is still limited. That means quality varies a great deal from one seller to the next. The checks on this page are the best protection a family has before paying.
How do I check whether a laboratory is NABL accredited?
Ask the seller for the name and address of the laboratory that runs the test, then look it up on the NABL website. Check that its accredited scope includes genetic or molecular testing, and not only routine blood tests.
Can I use a saliva kit instead of a blood test?
Saliva can give a reliable inherited result when the laboratory is equipped for it. There are exceptions, such as people who have had a bone marrow transplant or have a blood cancer. Tell the counsellor your history before choosing the sample type.
My kit report shows a variant. What should I do first?
Do not change anything yet. Take the full report to a genetic counsellor or your oncologist. They will check whether the finding needs confirming, what it means for you, and whether relatives should be told.
Is a kit cheaper than testing through a hospital?
Sometimes the headline price is lower. The total cost can rise once you pay separately for counselling, confirmation and follow-up. Compare what is included, and ask whether Aarogyasri, Ayushman Bharat or your insurer covers any part of hospital testing.
Will the company share my DNA with anyone?
It depends entirely on the company. Read the privacy terms before buying, not after. Look for whether samples are stored, whether data is shared for research, and how you can ask for your sample and data to be deleted.
Should my whole family buy the same kit?
Usually not. The best first step is testing the relative who already has cancer. If a fault is found, others are then tested for that one change, which is quicker, cheaper and gives a much clearer answer than several broad kits.
Where do I start if I am unsure a kit is right for me?
Write down who in the family had cancer, which kind and roughly at what age. Take that list to a genetic counsellor or your oncologist before buying anything. Call the CION helpline if you are not sure who to approach, and we will point you to the right clinic.
