Why is it important to send specimens in a watertight container?

Sending specimens in a watertight container is important primarily to prevent contamination and leakage. When phlebotomy specimens are collected, they might contain biological material that could pose a risk to both the environment and individuals who may handle the package. A watertight container ensures that any fluids remain contained, thereby minimizing the risk of spills that could lead to contamination of other specimens or environments. This containment is critical not only for the integrity of the sample being tested but also for ensuring safety during transport.

Contamination could result in inaccurate lab results, which could lead to misdiagnosis or inappropriate treatment for the patient. Additionally, it helps maintain the sample's viability, allowing accurate laboratory processing and analysis upon arrival. While compliance with shipping regulations and expediting laboratory processing are important considerations, the primary need for a watertight container centers on safety and the preservation of specimen integrity during transit.
