Clinical Biochemistry — NABL criteria
NABL 112A, section 7.1 — Technical Requirements, Discipline Wise
Checked against NABL 112A (Issue 01, 18-Dec-2024) · page updated 23 September 2026
NABL 112A carries only a short discipline-specific section for Clinical Biochemistry. That is not an oversight and it does not mean fewer obligations — almost everything that governs this discipline sits in the general technical requirements that apply to every laboratory: quality control, method verification, calibration, competency and reporting. Those are the records listed at the foot of this page.
What NABL 112A requires of this discipline
- Appropriate controls for body fluid chemistry wherever available shall be used.
- Storage period of examined specimen The examined specimens shall be stored for re-examination and / or additional tests for a minimum period of 1 day at 2-8°C except for unstable parameters.

- EQA / Proficiency Testing Participation Record
- Method Verification Record
- Method Validation Record
- Measurement Uncertainty (MU) Record

HealthFlow is not NABL accredited and is not an accreditation body. Using it does not make a laboratory accredited or compliant. These pages describe what the standard requires; meeting it is the laboratory's own responsibility.
What the software contributes is evidence produced by normal work: turnaround time measured per test, reports versioned and locked on authorisation with dual signatures, every report access written to an append-only audit trail enforced at the database and retained two years, and full export whenever you want it.
