Accreditations & quality
Standards
The benchmarks a diagnostics lab is held to
These are the standards that govern medical testing. Our accreditation certificates and registration numbers are displayed at the centre and confirmed on request.
National Accreditation Board for Testing and Calibration Laboratories
The benchmark for medical testing laboratories in India. NABL accreditation means a laboratory's competence — its methods, its equipment calibration, and the quality of its results — has been formally assessed against ISO 15189.
Registration: Certificate MC-2491, granted to Charakdhar Diagnostics Private Limited against ISO 15189:2022 in the field of Medical Testing, for the facility at Basement, 292/05 Tulsidas Marg, Chowk, Lucknow. Issued 21 December 2025, valid until 20 December 2029.
Medical laboratories — quality and competence
The international standard specifically for medical labs, covering everything from how a sample is collected and handled to how a result is validated and reported. It is the standard NABL assesses against.
Registration: The standard this centre's NABL accreditation (MC-2491) was assessed against, in its 2022 revision.
Quality management systems
A management-wide standard that a centre runs consistent, documented processes and continually improves them — the discipline behind a result you can rely on, visit after visit.
Bio-Medical Waste management
Compliance with the Bio-Medical Waste Management Rules — the safe segregation, handling and disposal of clinical waste, which protects both patients and the community.
Documents, not adjectives
Our quality management system
Accreditation is a certificate somebody else grants. A quality system is what you run every day — and ours is written down, issued and revision-controlled.
Laboratory Quality Manual
The manual that defines the organisation, its reporting lines and its named technical managers. Issue 02, dated 1 May 2025, prepared by the Quality Head, reviewed by the Lab Director and released by the Administrative Officer.
See the structure it defines →Quality System Procedures — process flow
The controlled flow every sample follows: registration into the LIS, preparation check, barcoded collection, section testing, verification against the record, pathologist authentication, dispatch — and the loops back for a repeat test or a fresh sample.
Follow the process flow →Specimen Rejection Record
Pre-examination quality form. Every rejected specimen is logged with its date and time, the reason for rejection, and the corrective action — including when the sample was recollected.

CGHS empanelment — recommended
NABH, a constituent board of the Quality Council of India, recommended the centre for CGHS empanelment on 14 October 2025 (ref. NABH-CGHS-LAB/2025/C0330/2025/10630). The recommended scope covers X-Ray, OPG, MRI, CT, Mammography, USG and Colour Doppler, Bone Densitometry, FibroScan, PFT, 2D Echo, EEG, ECG, Holter and TMT. A recommendation for empanelment is not itself an accreditation — it is recorded here as what it is, and the empanelment decision rests with CGHS.
The quality manual and controlled documents behind all of this are the centre’s own. Ask at the desk and we will show you the current certificate and documents.
Every day, not just at audit
What quality looks like in practice
- A documented Laboratory Quality Manual, issued, dated and revision-controlled
- A written process flow every sample follows, from registration to dispatch
- Named Technical Managers and Authorised Signatories for haematology, biochemistry and molecular testing
- Barcoded sample identification from the moment of collection, matched against the LIS before testing
- Pathologist authentication before any report is released — an unusual result is repeated, not reported
- A Specimen Rejection Record logging every rejected sample, its reason and the corrective action taken
- A feedback loop written into the process itself, so what goes wrong is analysed rather than only fixed
