Third-party Quality Controls for Haemostasis

Haemostasis controls from Helena Biosciences Europe

Helena Biosciences offer extensive batch sizes with a long shelf life allowing use of the same lot number over multiple changes in reagents and calibrators. This enables each laboratory to detect shifts or a drift in results which may occur within the test system.

Using independent control material offers wide ranging benefits including:

Sensitive monitoring of any shift in test system performance.
Control material traceable to WHO standard reference material.
Multiple level quality control analysis throughout the analytical range and critically at the clinical decision level.
Long term QC monitoring.
Detection of critical analytical system and reagent issues.
