Happiest Diagnostics, a unit of Happiest Health, has received
accreditation from the National Accreditation Board for Testing and Calibration Laboratories
(NABL), marking a significant milestone in its growth journey. The accreditation was achieved
within just two years of inception, reflecting strong governance and early maturity of quality
systems.

From inception, Happiest Diagnostics designed, commissioned, and operated its laboratories in
alignment with NABL guidelines, enabling a smooth and structured accreditation process. The
organisation places a strong emphasis on accuracy, reproducibility, and traceability across its
diagnostic services, with an uncompromised focus on clinical quality.

Speaking on the broader vision, Mr. Ashok Soota, Chairman & Chief Strategy Officer, Happiest
Health, said, “Our vision is to build a future-ready diagnostics platform governed by strong
quality systems, capable of handling complex biological data, and scalable for advanced testing
needs. This milestone strengthens our foundation to systematically expand into molecular,
genomic, and preventive diagnostics, supporting how medicine will increasingly be practiced
over the next decade.”

NABL accreditation provides a strong foundation for the continued expansion of the company’s
accredited test menu and supports its progressive move into advanced diagnostics, including
molecular and genomic testing. The diagnostic roadmap is aligned with preventive, predictive,
and personalised healthcare needs, with an emphasis on introducing rare and clinically
significant tests that remain under-available in routine diagnostic settings.

Mr. Davis Karedan, Co-Chairman & COO, Happiest Health, added, “For us, NABL accreditation
is not just a regulatory milestone it directly impacts the Atithi experience. It assures patients
and clinicians that every report is built on rigor, consistency, and trust. As diagnostics becomes
central to clinical decision-making, our focus is on delivering an experience that is accurate,
transparent, and dependable at every touchpoint from sample collection to interpretation.
This accreditation reinforces our commitment to making advanced diagnostics both clinically
reliable and patient-centric.”

While the current NABL accreditation marks an important milestone, Happiest Diagnostics is
concurrently building a large reference laboratory that will significantly expand its accredited
test portfolio nearly tripling its current offerings while enabling advanced and specialised
testing capabilities. The reference lab is envisioned as a central hub for quality, standardisation,
and complex diagnostics, supporting the organisation’s next phase of growth across molecular,
genomic, and data-intensive testing.

As part of its advanced diagnostics portfolio, Happiest Diagnostics has also introduced Gut
Microbiome Testing, leveraging high-throughput sequencing and bioinformatics to analyse over
5 GB of microbial genomic data per sample. This data-intensive test provides clinically relevant
insights into digestive health, metabolic balance, immune modulation, and overall wellness,
reinforcing the organisation’s focus on preventive, predictive, and personalised diagnostics.

Dr. Bikash Kumar Chaudhury, CEO & Senior Vice President, Happiest Diagnostics said
“Diagnostics today plays a central role in clinical decision-making across prevention, diagnosis,
and long-term care. Receiving NABL accreditation validates the strength of our quality and
clinical frameworks, reinforcing confidence in the accuracy and reliability of our reports. This
milestone supports the expansion of our clinical offerings, particularly in advanced and data
intensive diagnostics, while ensuring complex biological data is governed responsibly. Our focus
remains on delivering clinically actionable insights that enable early intervention and support
personalised, preventive healthcare.”

Looking ahead, Happiest Diagnostics plans continued investments in automation, quality
systems, and advanced diagnostics, with a long-term aspiration to build a future ready,
clinically rigorous, and nationally trusted diagnostic ecosystem.
