General Sample Submission Guidelines

To ensure the accuracy, integrity, and efficiency of laboratory analysis, it is essential that all samples are submitted according to established protocols. Failure to adhere to these guidelines may result in delays, rejection of samples, or compromised analytical results.

1. Sample Preparation and Labeling

Proper preparation is the foundation of reliable data. Please observe the following requirements:

• Unique Identification: Every sample must be clearly labeled with a unique identifier that matches the information provided on the submission form.
• Containment: Use appropriate, chemically inert containers that prevent leakage, contamination, or cross-contamination during transit.
• Volume/Mass: Ensure the quantity provided meets the minimum requirements specified for the requested analysis. Providing insufficient sample material may prevent re-analysis if necessary.

2. Documentation

A completed Sample Submission Form must accompany every shipment. This document serves as the legal record of the transfer and must include:

3. Packaging and Shipping

Samples must be packed to withstand the rigors of transportation. Guidelines include:

• Temperature Control: If the samples are temperature-sensitive, use insulated packaging with appropriate refrigerants (e.g., cold packs or dry ice).
• Secondary Containment: Use leak-proof secondary packaging for liquid samples to prevent exposure to handlers.
• Shipping Method: Ship samples via a reliable courier, ensuring they arrive within the laboratory's operational hours. Avoid weekend deliveries unless prior arrangements have been made.

4. Chain of Custody

For regulatory or legal purposes, maintaining a clear chain of custody is mandatory. This includes documenting every individual who has handled the samples from the point of collection to the laboratory receiving dock. If a seal is broken or tampered with, the laboratory must be notified immediately.

5. Rejection Policy

The laboratory reserves the right to reject samples that do not meet the following criteria:

• Samples received without appropriate identification or documentation.
• Samples that have exceeded their recommended holding time.
• Containers that are broken, leaking, or improperly sealed upon arrival.
• Samples that pose an undisclosed safety risk to laboratory personnel.

6. Communication

If you anticipate any issues with your shipment, such as delays or specialized requirements, please contact the laboratory manager prior to dispatch. Advance notice allows the laboratory to prepare the necessary equipment and personnel to handle your samples promptly upon arrival.
