What container is recommended for sending frozen sections to the lab?

  1. Formalin jar

  2. Dry specimen container

  3. Saline solution container

  4. Plastic bag

The correct answer is: Dry specimen container

A dry specimen container is the appropriate choice for sending frozen sections to the laboratory. This is because frozen sections typically require the tissue to be preserved in a manner that avoids any form of fixation that could compromise the rapid diagnostic process. A dry container prevents any introduction of formalin or saline, which might alter the tissue's cellular architecture and affect the histological evaluation. For frozen section analysis, the tissue is usually frozen rapidly and directly, without the addition of fluids that could lead to thawing or degradation of the sample. Using a dry specimen container also ensures that there is no risk of contamination or moisture, which is crucial when the samples are being prepared for immediate analysis. Understanding the requirements for specimen handling is vital in maintaining the integrity of pathological specimens for accurate diagnoses, and using the correct transport container is a critical aspect of this process.
