WHO’s QC requirements

Historically, when it comes to the immunohistochemical (IHC) staining process for biopsy sections, it has been virtually impossible for any laboratory in the world to process co-resident control materials and patient samples on a single slide in accordance with the World Health Organization’s (WHO) strict requirements. In addition to the quality control material missing for each test, there has never been a calibrating system available to track and improve the IHC process.

However, this is now all possible with the introduction of the PRS product which provides a cost-competitive solution vs. the available IHC compatible adhesive-coated only slides.
