Thalassaemia and sickle cell carrier checks for couples before pregnancy
TL;DR Duetcheck tests couples who are planning a pregnancy for thalassaemia and sickle cell carrier status, then gives at-risk pairs genetic counselling and options. Employers, fertility clinics and obstetricians offer it as a benefit or add-on. It works because the blood test is cheap and the disease it prevents is very costly.
A haematologist writing in October 2026 estimates that about 10,000 Indian children are born with thalassaemia major and 40,000–42,000 with sickle cell disease each year, and puts lifetime thalassaemia care at ₹50 lakh to over ₹1 crore[1]. He cites 40–50 million carriers, but a per-capita carrier rate of 3–4% suggests that figure may be high, so check it.
Most couples learn their status only during pregnancy, if at all. One Indian programme screened 33,270 pregnant women before 20 weeks and found 6.8% were carriers. It identified 339 at-risk couples, and in 44 of the 65 affected pregnancies the family chose termination[2]. Testing before conception gives couples more choices, including IVF with embryo testing.
What it does, in regulatory terms: carrier screening and genetic counselling for adults. It is not prenatal diagnosis, and it never tests for or discloses the sex of a fetus. Any later prenatal testing is done by a registered centre under the PCPNDT Act, which bans sex determination[3].
The seed proposed broad genomic "compatibility" testing, and I reframed it. Wide panels sold as partner-matching produce many uncertain results and invite misuse in arranged-marriage settings. Duetcheck tests only what is common, serious and actionable in India - beta-thalassaemia, sickle cell and related haemoglobin variants.
Each partner gives a blood sample at a workplace camp, clinic or home visit. A partner lab runs a blood count and HPLC, the standard carrier screen[1]. If only one partner carries a variant then the couple gets a plain-language report. If both do, a certified genetic counsellor calls within a week, DNA confirmation follows, and the couple is referred to a fertility or fetal-medicine centre if they choose.
The users are couples aged roughly 22–38 planning children. Three payers are realistic - employers adding it to a wellness or fertility benefit, IVF and obstetric clinics bundling it into first visits, and couples paying directly. I found no public price list for couple carrier screens in my checks. My assumption is ₹1,500–3,000 per couple for screening, with counselling and DNA confirmation charged separately.
The National Sickle Cell Anaemia Elimination Mission aims to screen 7 crore people in about three and a half years across 17 states[4], which raises public awareness but focuses on the young in high-burden areas. Urban couples outside that net remain unscreened. Corporate fertility benefits and IVF use are growing, giving ready channels.
There is no public figure for preconception carrier screening in India. The bottom-up case is the 50,000-plus affected births a year[1] and the near-complete partner testing seen when screening is offered properly[2]. Adjacent: IMARC values India's genetic testing market at US$1.96 billion in 2025 (about ₹19,000 Cr)[5]. That is context, not this market.
Government programmes screen pregnant women and, under the sickle cell mission, children and young adults in priority states[4]. Large diagnostic chains sell HPLC tests, but as single lab items, not as a couple service with counselling. A US nonprofit founded in 1983 runs anonymous premarital carrier matching for Jewish communities and had tested over 200,000 people by 2006[6]. The gap in India is a couple-focused service that includes counselling and referral.
| Difficulty | Moderate (44/100) |
| Starting capital | ₹60 L–1.1 Cr |
| Time to launch | 6–9 months |
The lab test is routine and partner labs can run it. The hard parts are hiring enough trained genetic counsellors, reaching both partners rather than just one, and selling to HR teams that see it as a niche benefit with few takers.
Yes. Carrier screening sits close to prenatal law, so the rules matter from day one.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't trust AI to read HPLC results or counsel a couple. This stays carrier screening, and a certified counsellor handles every at-risk result.

Here's what can go south -
I like this for a founder from diagnostics, fertility or genetic counselling who can run a clinical service carefully. If you want an app-only consumer product then it's a poor fit. First prove that an employer or clinic channel gets both partners tested in at least 70% of couples.
Expect roughly ₹60 L–1.1 Cr, mostly counsellors, lab partnerships and running the first camps. The free kit has the line-by-line capital breakdown.
You need to stay within the PCPNDT Act, register under the Clinical Establishments Act where it applies, and follow DPDP consent rules.
Yes, anywhere thalassaemia or sickle cell is common. Check your local genetic testing and prenatal laws first.
The free Duetcheck validation kit has the line-by-line capital breakdown, the effort scoring, the PCPNDT, lab and data-protection checklist, a 14-day validation sprint with pass/fail targets, a 90-day launch plan, 10 interview questions for couples, employers and clinics, and 5 assumptions to test.

Thinking about building Duetcheck or something close to it? The make-or-break work is getting both partners tested and staffing enough trained counsellors. If you need a hand, you know where to find me. Talk to Yash →
