About Us

Introducing PRS – the Process Record Slides – the new, innovative quality control measure for immunohistochemistry (IHC) staining that ensures accuracy and reproducibility of results while meeting the requirements of ISO 15189.

Traditional tissue controls can be limited by issues such as lack of standardization, batch-to-batch variability, and potential misuse by pathologists. PRS provides a reliable alternative by consisting of primary and secondary protein targets with known antigen expression levels that are certified as an ISO 13485 medical device.

Unlike traditional tissue controls, PRS can be standardized, providing a reference material with known properties appropriate for the examination. This ensures that each IHC staining run is checked for accuracy and reproducibility, rather than relying on the accuracy of previous batches.

Using PRS for 100% process QC for each IHC staining run ensures that the staining process is working correctly for each individual slide, rather than relying on the accuracy of previous slides. This approach guarantees that laboratories can achieve accreditation and compliance with regulatory standards such as ISO 15189, CLIA, and CAP.

Switch to PRS today for a reliable, standardized, and compliant quality control measure that ensures the accuracy and reproducibility of your IHC staining results.
