The Importance of Lab Accreditation in Nigeria
In Nigeria’s evolving economy—from healthcare to manufacturing, environmental monitoring to food safety—the reliability of laboratory test results is crucial. That’s why accreditation of laboratories has become a central issue. A laboratory’s accreditation signals it has met specific standards of technical competence and operates under a robust quality management system. In short: accreditation builds trust. But why does it matter, especially in Nigeria? Let’s explore.
What does accreditation mean in a Nigerian context?
Accreditation refers to a formal recognition that a laboratory is competent to carry out specific tests, calibrations or measurements under internationally-oriented standards (such as ISO/IEC 17025 for testing and calibration laboratories).
In Nigeria, organisations such as the Nigeria National Accreditation System (NiNAS) and other regulators recognise accreditation as the means to guarantee credible lab data. For example, one Nigerian laboratory received full WHO-linked accreditation under ISO 15189 for measles and rubella diagnosis.
In the environmental test-lab space, guidelines from the Federal Ministry of Environment emphasise that accreditation “provides national/international recognition of technical competence” along with confidence in results. EAD
Why accreditation matters for Nigeria’s labs and stakeholders
1. Trusted results, for healthcare, industry and regulation
When a laboratory is accredited, the results of its tests (for example, chemical analyses, calibration of equipment, environmental monitoring) are more likely to be accurate, consistent and reproducible. As studies across sub-Saharan Africa show, accreditation is associated with improvements in laboratory processes and result quality. BioMed Central
For Nigeria, this means better-informed decisions in healthcare (diagnosis), food safety, environmental protection, mining and manufacturing. A result from an un-accredited lab may raise doubts or incur regulatory re-testing.
2. National and international recognition, trade and confidence
Accredited laboratories are better positioned to serve export-oriented industries, international regulators or global value-chains. For example, the accreditation of the Raw Materials Research and Development Council (RMRDC) lab by NiNAS in December 2024 was hailed as boosting Nigeria’s industrial standardisation and export capability.

This means that companies working with Nigerian labs can trust that their analytics meet global norms, which opens markets and supports value-addition.
3. Efficiency, cost-reduction and risk-management
Accredited labs tend to have better quality management systems—fewer errors, systematic calibration of equipment, documented procedures, external proficiency testing. For clients, that means fewer retests, fewer disputes, and more predictable operations. The Nigerian environmental guideline underscores that accreditation “reduces operating costs … by getting results right the first time and every time”. EAD
For regulatory bodies and private companies, that helps reduce risk of mis-testing, recalls, regulatory penalties or failed product shipments.
4. Supporting national systems and public trust
In healthcare specifically, accreditation reinforces public health frameworks. A lab-result error can have serious consequences—misdiagnosis, wrong treatment, outbreak mis-management. In Nigeria the survey of medical labs found major gaps: none of the sampled labs in one region were formally accredited, pointing to systemic weaknesses. ej-med.org
Accreditation helps raise the standard of laboratory services, which builds public trust in diagnostics, environmental monitoring, regulatory enforcement and overall institutional credibility.
Key steps and considerations for Nigerian labs seeking accreditation
- Understand the relevant standard: For testing and calibration labs, ISO/IEC 17025 is often the reference. For medical labs, ISO 15189 may apply. BioMed Central+1
- Implement a quality management system (QMS): Documented procedures, management review, internal audits, equipment calibration, external proficiency testing—these are the building blocks of accreditation.
- External assessment and proficiency testing: Accrediting bodies evaluate technical competence via onsite audits, participation in inter-lab comparisons and proficiency tests.
- Continuous improvement: Accreditation is not a one-time event but requires ongoing compliance, monitoring, corrective action, and renewal.
- Stakeholder alignment: Labs should engage with clients, regulators, suppliers and quality-systems personnel to align workflows and documentation.
Common challenges facing accreditation in Nigeria
Nigeria has made progress, but several hurdles remain:
- Infrastructure deficits: Some labs struggle with erratic power supply, outdated equipment or lack of SCI-traceable standards. The review of clinical lab frameworks in Nigeria highlights infrastructure, staffing and policy gaps as barriers. IOSR Journals
- Cost and resource intensity: Accreditation requires investment—equipment, staff training, quality systems, external audits. For smaller or public labs, this may strain budgets.
- Fragmented oversight and slow regulation: Though guidelines exist, enforcement and harmonisation of quality management systems across sectors are uneven.
- Limited awareness: Some labs may confuse licensing with accreditation, but accreditation requires technical competence and external certification beyond basic registration.
Final thoughts: Why accreditation is a national imperative
For Nigeria’s economic development, public health, environmental protection and global trade ambitions, lab accreditation is not optional—it is fundamental. Accredited laboratories deliver reliable data, uphold standards, reduce risk, and build confidence both domestically and internationally.
When a Nigerian laboratory carries that accreditation badge, it says: “We have the systems, the competence, the documentation—and you can trust the results.” That matters for doctors diagnosing patients, for manufacturers verifying product quality, for regulators guarding consumer safety, and for exporters accessing international markets.
By advancing accreditation across labs in Nigeria, we take a concrete step toward stronger institutions, better services and higher-value outcomes. In short: accreditation underpins credibility—and that credibility drives progress.
