\nBoth the GLC2B and GLC2D protocols are calibrated via a 2-point linear regression curve. However, in the case of the GLC2D protocol, the calibrator is first diluted 1:10 to create the first standard. The second standard is water. In general, when the system performs an automatic dilution step to create a standard, the system only requires information about the lot-specific concentration of the analyte, provided in the Instructions for Use for the relevant calibrator. Therefore, the system will not ask for information about a second standard in the case of the GLC2D protocol.", "Name": "Protocols - Help Corner" }, { "Language": "English", "Value": "Method: Enzymatic photometric assay using hexokinase.

Conversion Factors
Conversion factors for analyte concentration:

• 1 mmol/L = 180.2 mg/L
• 1 g/L = 5.550 mmol/L

Traceability
This method has been standardized against Isotope dilution mass spectrometry (ID-MS).

Precision
Representative performance data on Cedex Bio analyzers are shown. Results obtained in individual laboratories may differ.
Precision was determined in samples of three concentration levels. Coefficients of variation (CV) were calculated for in-run precision (n=21) and inter-run precision (on 10 days).
