The SPORE TEST should be performed at which frequency?

Correct answer: A. Weekly

• A. CDC and ADA recommendations require biological spore testing (Bacillus stearothermophilus for steam autoclave) at least WEEKLY to verify sterilizer efficacy. The spore test is the GOLD STANDARD for sterilizer monitoring. Daily chemical indicators confirm cycle parameters; weekly spore tests confirm actual sterilization. Note: The source states the EXAM had this question in TWO BLOCKS — one answer was 'monthly' and one was 'weekly.' Both answers are reportedly on the exam. The source author got the weekly question.
• B. Daily biological spore testing is not required — daily monitoring uses chemical integrators/indicators, not spore tests.
• C. Annual spore testing is completely insufficient — weekly is the minimum standard.
• D. Monthly spore testing is insufficient per current standards. ⚠️ FLAG: The source says the exam had BOTH 'monthly' and 'weekly' in different blocks for this question. See explanation below.
