Which term is defined as the standard by which measurements are compared across systems?

• A. Contaminant
• B. Baseline
• C. Biohazards
• D. Bloodborne

Answer: (B)

A baseline is the reference value used to compare measurements across different systems or over time. In infection control, you establish a starting point for a metric—such as environmental cleanliness, contamination levels, or process performance—so that all future measurements can be judged relative to that point. This provides a common standard, even when different devices, methods, or locations are involved, allowing you to see whether conditions have improved, worsened, or stayed the same. The other terms describe hazardous agents or conditions, not a reference point for comparing measurement results.
