BCS IHControls® make SPC possible for IHC
- Same formalin-fixed microbeads but this time as a suspension
- Same measurement traceability to a NIST reference standard
- Use a pipette or microapplicator to apply 1 microliter of the control onto the slide.
- Ideally, the control is on the exact same slide as the sample.
- Once the microbeads are on the slide, it’s handled exactly as you would for a tissue section.
How to Use IHControls®
For this representative example, the baseline IHControl® stain intensity is illustrated in the first panel . If the IHControls® stain intensity matches the Baseline, the readout would be Pass (center panel). If the IHControls® stain intensity is visibly lower than the “Baseline” then the readout would be “Fail” (right panel) and may warrant investigation.
Adopt Statistic Process Control (“Levey-Jennings”) Graphing
- Run the IHControls® on every tissue slide every day
- Establish control ranges
- METRIC analyzes IHControls® and produces the daily Levey-Jennings graph
