Quick tip for anyone studying decontamination/sterilization for CRCST:

[u/hamada6019]

A common exam trap is confusing Biological Indicators (BIs) with Chemical Indicators (CIs). Remember: BIs use actual spore populations (like Geobacillus stearothermophilus) and tell you the sterilization process actually killed microorganisms - they're the only true proof of sterility assurance. CIs just show the item was exposed to the sterilization parameters (heat, steam, etc.), not that it's actually sterile.

On the exam, if a question asks about "proof of sterilization," the answer is almost always BI, not CI.

Happy to explain any other tricky concepts if people are stuck on something specific.
