What is standard and control in chemistry?
Sample is absent in a blankKnown concentration of analyzed sample is present. To check for contamination of instruments, equipment, and chemical solutions. To check the calibration of instruments or set a standard curve used to calculate concentration of the analyte in question. What is the difference between a control sample and a standard?
Control Samples Control samples are similar to standards in that they are specimens like those taken from a patient and have known values. Unlike standards, however, control samples are used before each patient sample is processed. Using a control sample serves as a check on the accuracy of the test.What is the difference between control calibration and standard?
While calibrators are used to adjust customer systems to an established reference system or method, controls verify the recovery level of the standardized reagents and calibrators. Calibrators and Controls ensure reliability and consistency of assay results.- Used to monitor the precision of chemistry assays and instruments, clinical chemistry controls are available in assayed and unassayed versions and in liquid or lyophilized format to suit each laboratory's requirements.
