What is NOT TRUE about biological spore testing of autoclaves?

  1. Should be performed monthly
  2. Tests are performed with live spores
  3. Tests verify sterilization effectiveness
  4. Tests should be done after autoclave repairs
Show answer and explanation

Correct answer: A. Should be performed monthly

Spore tests should be performed AT LEAST WEEKLY (not monthly) per CDC/ADA guidelines, and after repairs or failed cycles. The spores used are Geobacillus stearothermophilus (heat-sensitive). The test verifies complete sterilization. Monthly testing is insufficient and does not meet current standards.
