What are the two main methods of specimen transport?

The identification of refrigerated transport and ambient temperature transport as the two main methods of specimen transport is rooted in the requirements for maintaining specimen integrity during transit.

Refrigerated transport is essential for preserving biological samples, as many specimens require temperature regulation to prevent degradation, enzymatic activity, or bacterial growth. This method ensures that the samples remain viable for accurate analysis when they reach the testing laboratory.

On the other hand, ambient temperature transport involves sending specimens at room temperature, which is suitable for many types of specimens that are stable enough to withstand such conditions without compromising their integrity. This method is typically employed for non-sensitive samples or those that do not require strict temperature controls.

Other methods mentioned in the options may be relevant in specific contexts, but they do not categorize the primary transport methods based on temperature management, which is crucial in laboratory settings to ensure accurate testing and results.
