Tested lot by lot, released against defined limits.
Every performance claim on this site corresponds to a test carried out on the production lot before it leaves us.
Human matrix, so the check is real
Our POCT controls are based on human serum and blood. That matters because a control only verifies a device if it behaves on that device the way a patient sample does. Artificial or heavily modified matrices can interact differently with the reagent system, producing matrix effects that either hide a genuine problem or imitate one that does not exist.
Working with a human matrix keeps matrix effects minimal and makes the control result directly comparable to patient results on the same analyser.
Analyte stability, measured in real time and under stress
Real-time stability
- Study design
- Measured at defined time points after manufacturing, expressed in weeks
- Replicates
- Each sample measured three times at every time point
- Recommended shelf life
- 12 weeks for blood-based POCT CRP and POCT glucose controls
Accelerated stability
- Stress condition
- One week of incubation at 37 °C
- Reference condition
- Samples stored at +2 to 8 °C
- Replicates
- Triplicate measurements for each condition
- Acceptance
- A change of less than 20% between conditions is expected
Stability data for a specific lot is provided with the lot documentation on request.
The same material in every vial, and in the next lot
Vial-to-vial homogeneity
Random vials are selected after filling and tested in accordance with ISO 13528. After statistical evaluation, batches are released using the total allowable error limits for CRP and glucose defined in the Rilibäk guideline.
Minimal lot-to-lot variation
Consistent target values are maintained across production lots, which gives familiar results and keeps long-term quality records comparable.
Clinically relevant levels
Levels are chosen to assess assay performance in relation to the assay range and to the critical values that matter for clinical decision making.
Ready to use, by design
Verilox controls are supplied as ready-to-use liquid material. There is no reconstitution step, no weighing and no dilution at the point of care, which removes a common source of operator error and makes the control faster to run in a busy clinical setting.
