Measurement system for determining analyte information of a test sample

摘要

A measurement system (2) for determining analyte information of a test sample comprises a reader (16) for reading into the measurement system (2) data held in an information unit of a portable holder (18) containing a reference material. A measurement instrument (10) is provided that operates according to a first measurement methodology to generate reference measurement data to be employed within the system (2) in determining analyte information of the reference material. The data processor (12) is configured to effect a comparison of so determined analyte information of the reference material with corresponding expected analyte information obtained from the data read into the measurement system (2) generated by a second, different measurement methodology and to generate a signal dependent on the comparison for subsequent use within the measurement system (2).
