Nucleic acid hybridization detection IVD, control

This category consists of control materials used to verify the performance of in vitro diagnostic assays that detect nucleic acid hybridization, such as those used in fluorescent or chromogenic in situ hybridization (FISH/CISH) tests. These controls help ensure that the assay is functioning correctly by providing known positive or negative signals for the target nucleic acid sequences in a clinical specimen.

As controls for nucleic acid hybridization detection IVDs, these materials are regulated as part of the diagnostic assay system and are intended solely for quality assurance purposes. They do not contain patient samples, are not used for direct diagnosis, and are supplied to laboratories to confirm reagent integrity, procedural accuracy, and instrument performance according to the assay manufacturer’s instructions.
