India's diagnostics market is led by a handful of large chains and fast growing home collection companies. Dr Lal PathLabs reports more than 310 labs and 7,725 patient service centres, Agilus Diagnostics processed 40.8 million tests in FY26, and Healthians says it processed 38 million tests in FY 2025 to 26. This list compares ten major chains using company websites, filings and investor presentations.
How we chose these chains
We included diagnostic companies that run their own laboratory networks in India today and publish lab counts, centre counts or test volumes. The list covers listed pathology chains, integrated pathology and radiology chains, a public-private partnership specialist and home collection companies.
The order is not a ranking and we make no claim about test accuracy. Network figures are self-reported by each company on its website or in filings and use different terms such as labs, centres, touchpoints and pick-up points. Each fact gives the company's own term.

Quick comparison
The table shows a headline network figure for each chain. Treat these as indicators of scale, since companies count collection points and centres in different ways, and confirm whether the specific lab near you is NABL accredited for the test you need.
| Chain | HQ | Key figure |
|---|---|---|
| Dr Lal PathLabs | New Delhi | 310+ labs, 7,725+ centres |
| Metropolis Healthcare | Mumbai | 210+ labs, 750+ towns |
| Agilus Diagnostics | Gurugram | 40.8 million tests in FY26 |
| Thyrocare | Navi Mumbai | 1,122 outlets (2021) |
| Vijaya Diagnostic Centre | Hyderabad | 200 centres, 6 states |

How to choose a diagnostic lab
Check that the processing lab, not just the collection centre, holds NABL accreditation for your test. For specialised tests such as genetics or molecular panels, ask where the sample will be processed and how long the report takes. Home collection is convenient, but confirm cold chain handling for sensitive samples.
Compare package contents rather than headline prices, since wellness packages vary widely in which parameters they include. If your doctor needs to track results over time, using the same lab for repeat tests makes trends easier to read, because reference ranges and methods can differ slightly between labs.
- Confirm NABL accreditation of the processing lab
- Ask for turnaround time in writing
- Compare parameters, not just package price
- Use one lab for repeat monitoring
Market context: hospital-linked and home-first models
Two models are growing side by side. Hospital groups own large lab businesses: Fortis holds about 57.68% of Agilus, which earned ₹1,527 crore gross revenue in FY26, and Apollo lists 2,450+ diagnostic centres. Home-first players such as Healthians and Redcliffe report presence in 350+ and 220+ cities respectively.
As test volumes rise, labs and the hospitals they serve handle more billing, claims and report data. XDQ Labs builds software for healthcare operators, but no company on this list was chosen or ordered on the basis of any commercial relationship.
Frequently asked questions
Which is the largest diagnostic lab chain in India?
Scale depends on the measure. Dr Lal PathLabs reports 310+ labs and 7,725+ patient service centres, Metropolis reports 210+ clinical labs, and Agilus processed 40.8 million tests in FY26. Companies count labs and centres differently, so compare the same measure across chains.
What does NABL accreditation mean for a lab?
NABL is the National Accreditation Board for Testing and Calibration Laboratories. Accreditation means an external assessor has audited the lab's processes, equipment and staff competence for specific tests. It applies to particular labs and tests, so check the certificate of the lab that will actually process your sample.
Which diagnostic companies offer home sample collection?
Most large chains now offer home collection. Healthians reports 2,400+ trained phlebotomists in 350+ cities, Redcliffe Labs reports 2,000+ collection centres in 220+ cities, and Suburban Diagnostics reports more than 1,000 home visits a day. Check that home collection is available at your pin code before booking.
Is this list ranked by test accuracy?
No. The chains are listed in no particular order using public information such as lab counts, centres, test volumes and revenue. We do not assess or rank test accuracy. Ask your doctor which lab they trust for your test, and check NABL accreditation for the processing lab.
