The QuantiFERON Control Panel consists of 3 sets of interferon-gamma (IFNγ) controls made up of recombinant human IFNγ lyophilized in an aqueous buffered solution. Each complete set consists of 3 individual controls that represent different IFNγ concentration levels (levels 1, 2, and 3) within the linear range of QuantiFERON assays (2).
Validated for QuantiFERON ELISA assays, the QuantiFERON Control Panel is a standardized IFNγ control for use in monitoring the accuracy of QuantiFERON ELISA assays. Use of the QuantiFERON Control Panel ensures consistent and reproducible results between both ELISA runs and operators (2), and will eliminate the current costs associated with the development, calibration, and validation of in-house IFNγ controls.
When reconstituted with distilled water, each set of 3 IFNγ controls is processed the same way as a patient's plasma samples.
The 3 IFNγ control levels contain different concentrations of IFNγ, and will provide results across the expected IFNγ range of the QuantiFERON ELISA platform. When reconstituted, the 3 controls should be tested as though they are plasma samples with a QuantiFERON ELISA assay, with their final, absolute IFNγ concentration values cross-checked against their assigned concentration IFNγ values.
The QuantiFERON Control Panel is to be used to monitor the performance of QuantiFERON ELISA assays, including QuantiFERON-TB Gold ELISA and QuantiFERON-CMV ELISA (2).
