Quality Controls

Bioanalytic offers different reference calibration solutions that can be used for external/internal quality control. They substitute for ringtests whenever the data evaluation method disallows them or when a reference solution is preferred.

The referenced Bioanalytic calibration solutions are issued with a unique lot number. The target value is not stated.

The lab sends an analysis form with the measured value(s) to Bioanalytic (fax, e-mail). The laboratory then receives a certificate from Bioanalytic containing the following data:
Reference value of the LOT.
Submitted test result with date.
Deviation from the nominal value (value and %).
Any other required information on demand.
