Quality
Practices aligned with ISO 15189, quality control explained, and published indicators computed from the laboratory's records.
Our practices
Document control
Every procedure is versioned, signed and reviewed; staff read the version in force.
Competency
Every technician and biologist is authorised bench by bench, and reassessed.
Internal quality control
Controls run on each analyser several times a day, before patients' samples.
External assessment
The laboratory takes part in external quality assessment schemes.
Non-conformities
Every deviation is recorded, analysed and followed by a corrective action.
Practices aligned with ISO 15189; no accreditation is claimed here (to be checked with the Algerian accreditation body).
Quality control explained
Before measuring your samples, each analyser measures controls whose value is known. Their results are plotted day after day on a Levey-Jennings chart.
Rules (known as Westgard rules) detect a drift: a point too far out, two points in a row on the same side, a spread that grows.
When a rule is broken, the release of that test's results on that analyser is locked until the corrective action and a new control that passes.
