What is the Origin of Sample Transportation?

This practice is fundamental to modern clinical laboratory science and is governed by both national and international public health and transportation regulations, such as those for infectious substances. Its origin is tied to the need for standardization in diagnostic testing to ensure inter-laboratory consistency and accurate patient results. Failure to adhere to protocols compromises the integrity of the clinical sample.

What is the Mechanism of Sample Transportation?

The mechanism for preserving sample integrity during transport is based on controlling three primary variables: time, temperature, and physical containment. Specific specimens require precise temperature maintenance, such as refrigeration or freezing, to slow down enzymatic degradation or chemical alteration of analytes like hormones or metabolites. Proper triple-layer packaging and chain of custody documentation ensure biological safety, prevent leakage, and maintain an unbroken audit trail for the sample.

Sample Transportation

Meaning

Sample Transportation is the controlled, time-sensitive logistical process of moving clinical or biological specimens from the patient collection site to the analytical laboratory. This procedure is a critical pre-analytical step in the total testing process that directly impacts the validity and reliability of all subsequent diagnostic results. The process must adhere to stringent regulatory guidelines for packaging and handling to prevent degradation or contamination.
