For ammonia testing, a blood specimen requires immediate cooling because ammonia is a volatile compound that can rapidly degrade or change concentration when exposed to room temperature, leading to inaccurate test results. Cooling the blood specimen helps to stabilize the ammonia levels by minimizing its metabolic production and preventing the release of ammonia from cells.

While other specimens may also require specific handling procedures, such as urine specimens needing to be kept cool for certain tests, the immediate cooling requirement is most critical for blood specimens in ammonia testing to ensure the reliability and accuracy of the results.
