LGC Maine Standards, Cumberland Forest, Maine, has released Validate ACTH Linearity and Calibration Verification Test Kits for documentation of linearity, calibration verification, and analytical measurement range verification of adrenocorticotropic hormone (ACTH). The product is formulated in a human plasma matrix, using the CLSI EP06-A “equal delta” sample preparation method, and provides five distinct concentrations across the claimed range of the Elecsys-ACTH Method on the Roche cobas. Validate ACTH test kits are liquid and ready-to-use: Users dispense the solution from each dropper bottle directly into five sample cups and run in replicates to establish the assay’s reportable range.
