OSMT (Ontario Society of Medical Technologists) Practice Exam

Material that has been placed on agar, but not incubated, should be packaged:

1. a. as 1A

2. b. as 2A

3. c. as 1B

4. d. with dry ice

The correct answer is: c. as 1B

When material has been placed on agar but has not undergone incubation, it is considered to be at a stage where it may still be in a viable but dormant state. Packaging it as 1B is preferred for several reasons. Firstly, this classification indicates that the sample is not yet in an environment conducive for microbial growth, as it has not been incubated. Shipping it in this manner establishes appropriate handling procedures, ensuring that it is treated with caution until it can be properly analyzed. Moreover, categorizing the sample accurately helps maintain its integrity during transport. Given that it has not been incubated, there is no immediate need for temperature control measures that would be necessary for actively growing cultures—unlike options that suggest the use of dry ice, which is typically reserved for samples that require freezing temperatures to prevent spoilage or degradation. By utilizing the correct classification, technicians ensure that there are clear instructions for anyone handling the sample, preserving its condition until it is ready to be processed further. This systematic approach reflects best practices in laboratory management and ensures compliance with safety regulations.
