Sterility tests are destructive.

• A. True
• B. False
• C. Sometimes
• D. Not necessarily

Answer: (A)

Sterility tests are destructive because confirming that a product contains no viable microorganisms requires taking a sample and exposing it to growth conditions. The sample is placed into sterile culture media or filtered and then incubated to watch for microbial growth. In doing so, the material is consumed or structurally altered, rendering it unusable for its intended purpose. Because the test consumes the tested material, you can’t reuse the same unit after testing, so the process inherently destroys the sample even though it protects patient safety by verifying batch sterility.
