SAMPLES INFORMATION
The success of every analysis begins with the quality and completeness of the Chain of Custody (COC)/ Analytical Services Agreement form. The COC is a written document that refers to the authenticity of the collected samples and is crucial to provide valid, credible and legally sound laboratory test reports. The accuracy of laboratory findings is directly related to the accuracy of the sample collection. The COC is needed to ensure that the sample was collected utilizing proper protocol. Transportation, storage and handling of the sample sometimes influence lab results. Observation of the condition of the sample is important to consider before proceeding with the actual analysis. The lab bears the burden of proving that the sample was received, handled and analyzed by authorized laboratory personnel. For this reason, the lab makes note of any unusual characteristics of the sample.
