True or False: Stool specimens should be kept refrigerated.

Stool specimens should indeed be kept refrigerated to preserve their integrity and prevent the growth of bacteria or other microorganisms that may alter the results of the tests being conducted. When stool samples are collected, they can contain a variety of organisms and substances that are subject to degradation if left at room temperature for extended periods. Refrigeration helps stabilize the samples until they can be processed in the laboratory, ensuring that the results are reflective of the patient's condition.

Transporting specimens at lower temperatures is a common practice in laboratories to maintain the viability of any pathogens or agents that might be tested, which is central to accurate diagnostics. While preservatives can help stabilize some components in a stool sample, the general guideline is to refrigerate specimens if there's any delay in processing, ensuring their quality remains intact for testing.
