Essential Sample Submission Checklist

Submitting samples to a laboratory, testing facility, or research center requires precision and attention to detail. Whether you are submitting biological, chemical, or industrial samples, following a standardized checklist ensures that your samples arrive safely, remain viable for analysis, and are processed without administrative delays.

1. Pre-Submission Preparation

Before preparing your shipment, ensure you have communicated with the receiving facility. Always verify the following:

• Confirm the specific laboratory's requirements for sample volume or weight.
• Check if there are specific container material requirements (e.g., glass vs. plastic, sterile vs. non-sterile).
• Ensure you have the correct submission forms or electronic portals completed.
• Verify current operating hours to avoid samples sitting in transit over a weekend or holiday.

2. Labeling and Identification

Misidentified samples are the most common cause of processing errors. Every individual container must be clearly labeled.

• Unique Identifiers: Ensure every vial or container has a unique sample ID that matches your internal records.
• Durability: Use waterproof and smudge-proof ink. Ensure labels are resistant to the storage conditions (e.g., cryo-resistant if storing in liquid nitrogen).
• Legibility: If hand-writing labels, use block letters. Avoid ambiguous characters.

3. Packaging and Safety

The integrity of your sample depends on how it is packaged. Proper containment prevents leakage, contamination, and physical damage.

4. Documentation

A package without a clear manifest or submission form can lead to the disposal of samples or significant delays. Always include:

• Packing Slip: A printed copy of the submission form inside the box.
• Chain of Custody: If required, include documents that track the handling of the sample from collection to submission.
• Safety Data Sheets (SDS): If the sample is considered hazardous, an SDS must be included to ensure the safety of laboratory staff.
• Contact Information: Include the contact details for the person who collected the sample and the person who should receive the results.

5. Final Verification

Before sealing the package, perform a final walk-through of your process:

• Did you match the sample IDs on the paperwork to the physical labels?
• Is the container securely closed (and parafilmed if necessary)?
• Is the shipping address correct?
• Did you provide the correct tracking number to the laboratory so they can monitor the shipment's progress?

By following these steps, you minimize the risk of sample rejection or degradation. Consistent adherence to these protocols not only protects the scientific integrity of your data but also fosters a professional relationship with your analytical partners.
