PRS From Batch Control to 100% Quality Control

PRS Transforms IHC from Subjective to Precision Objective Decisioning

1. Definitive studies have emphatically revealed that IHC staining errors consistently exceed a staggering 10%.

2. Astonishingly, no IHC staining platform has ever undergone the crucial process of calibration.

3. The traditional dependence on tissue control lacks any scientific correlation proof to validate effective IHC staining. Using tissue control to assert specificity and declare IHC staining as effective is an outright logical fallacy.

4. The validation of specificity through reliance on tissue control must rigorously adhere to the standards of a class III device, as mandated by global regulations.

5. Immediately halt the misguided use of outdated methods such as tissue control and batch control in IHC assessments. Embrace a 100% Process Quality Control approach using PRS for precise and dependable results.

6. Relying on non-standardized and non-classified tissue control for IHC involving cancer diagnosis can lead to legal consequences. It’s comparable to persisting in the belief that the world is flat when everyone acknowledges its spherical nature.

Establish an antigen density baseline to go along with the physical morphology of the tissue section for use in Al training and eventual usage in diagnostic aid.

Establish an antigen density baseline to go along with the physical morphology of the tissue section for use in Al training and eventual usage in diagnostic aid.

Separate primary antibody , secondary stain , and antigen retrieval behaviors

Develop a quantitative link between antigen density and color density of the tissue

PRS is The only solution by which tele – diagnostic images can be color matched automatically while also regenerating the antigen & color density scales at the receiving end.

PRS At a Glance

Process Record Slide Limited, a Hong Kong Based startup, is dedicated to developing an economically viable on-slide process control and calibrator (PRS) for Immunohistochemistry (IHC) staining.

The Science behind PRS:

Despite IHC staining being invented in 1941 as a quantitative test, it has never achieved its intended quantitative function due to the lack of calibration and scientific validation.

The PRS system aims to replace on-slide tissue controls, providing an evidence-based quality indicator and enabling digital images to have a baseline ruler for precise quantitative analysis.

By eliminating non-standardized tissue controls, the risk of potential issues is mitigated, ensuring pathologists can rely on accurate results.

Process Record Slide Limited strives to revolutionize IHC staining, ushering in a new era of standardized and reliable diagnostic practices with profound implications for medical research and diagnostics.​
