What should the circulator do when a specimen is requested for permanent section?

When a specimen is requested for permanent section, placing it in a specimen container with formalin is essential. Formalin acts as a fixative that preserves the tissue's cellular structure and prevents decomposition. This preservation is crucial for accurate histological examination and diagnosis. The fixing process allows pathologists to study the specimen under a microscope and provide valuable clinical information regarding the patient's condition.

Using saline solution or gauze would not provide the necessary preservation and could compromise the ability to obtain accurate results from the pathological examination. Storing the specimen in a refrigerator is not suitable either, as refrigeration can cause changes in tissue that may interfere with the evaluation process.

In summary, utilizing formalin is the standardized practice for preserving specimens for permanent sections, ensuring that they remain viable for thorough analysis.
