What Are EMSL COC Forms Used For in Sample Integrity?

Definition and Purpose of EMSL COC Forms

EMSL Chain-of-Custody (COC) forms are essential documents used to maintain the integrity of samples collected for laboratory analysis. These forms serve multiple purposes, including:

• Authorization of Services: The COC form acts as a customer's official authorization for EMSL to perform specific analytical tests on samples, particularly when a formal contract or purchase order is not in place.
• Detailed Test Specifications: It outlines the exact analytical tests required, including the necessary turn-around time (TAT) and the number of tests needed for each sample.
• Legal Documentation: The form provides a documented history of the sample's handling, tracking who possessed the sample at various stages. This is crucial for legal evidence and ensuring the sample's integrity.
