Primary Standards: must have a known stoichiometry a known purity must be stable for long term storage Secondary Standards: have their concentrations determined relative to a primary standard It is crucial to know the amount of all other solution components when preparing standards (e g solvents acids )
PDF HOW TO ENSURE CORRECT calibration CALIBRATION

Two-point linear calibration curves are the most commonly used type of calibration for spectrophotometric methods in the biochemistry laboratory These calibrations typically use a blank and a known concentration of high standard to construct a straight calibration curve that is subsequently used to calculate the unknown concentration of samples

  • What is an example of a calibration change?

    An example of such calibration change is highlighted in igure 1. The calibration highlighted in Red is a passed calibration curve for an assay that conforms to the standard values provided by the manufacturer. This curve has the correct trajectory that can accurately calculate the concentration of the unknown using Beer-Lambert’s law.

  • What is the difference between a standard and a calibrator?

    Often, what are called standards in an immunoassay method are actually calibrators: either they are not in the same matrix as the target analyte (as is a standard), or else an analytically pure and immunologically active analyte is not available. Digoxin standards/calibrators provide a case-in-point.

  • What is a two point linear calibration curve?

    Two-point linear calibration curves are the most commonly used type of calibration for spectrophotometric methods in the biochemistry laboratory. These calibrations typically use a blank and a known concentration of high standard to construct a straight calibration curve that is subsequently used to calculate the unknown concentration of samples.

  • Why is calibration important in a clinical biochemistry laboratory?

    In the clinical biochemistry laboratory, it is important to appreciate and understand the fundamental principles of calibration curves and how to interpret results, as the quality of these determine whether IQC values pass or fail internal rules set by the laboratory.
