When a doctor makes a clinical decision—whether diagnosing diabetes, monitoring kidney function, or planning cancer therapy—the accuracy of the laboratory report is paramount. NABL Accreditation (MC-6849) under ISO 15189:2022 is the benchmark for medical laboratory competence.
At QXL Diagnostics, quality assurance encompasses three critical phases:
- Pre-Analytical: Temperature-controlled sample transport, barcoded primary tube validation, and standardized sample preparation.
- Analytical: Daily Internal Quality Control (IQC) using multi-level controls, regular calibration, and participation in External Quality Assessment Schemes (EQAS).
- Post-Analytical: Multi-layer result verification and clinical sign-off by senior consultant doctors (MD Pathologists, Biochemists, Microbiologists).
This rigorous framework ensures that every report delivered to patients and doctors meets international scientific standards.
