NGS Sample Shipping Checklist: 5 Requirements Before You Send

Written by Nataly Fishman | Jun 9, 2026 7:47:50 PM

Shipping samples doesn't have to be stressful. A little preparation before you seal the box can save you days of back-and-forth, prevent delays, and keep your next generation sequencing (NGS) project moving straight into processing. We put together this checklist, so your samples arrive ready to run, every time.

What to do before shipping NGS samples?

Sequencing labs require samples to meet specific preparation and packaging standards before they can be processed. Following these steps reduces the risk of resubmission, protects sample integrity during transit, and keeps your project on schedule.

  • Label Everything Clearly: All plates and tubes should be labelled and match your submission form exactly. If we can’t read it, we can’t run it.
  • Confirm Concentration & Volume: A quick measurement now can prevent a resubmission later.
  • Seal Securely: Plates tightly sealed + tubes firmly closed = No surprises during transit.
  • Pack with Purpose: Use racks, padding, and secondary containment so nothing shifts or leaks.
  • Include Documentation: Confirm your sample submission form has been uploaded and include a copy of your printed receipt if required.

Before you ship

Double-check all five items above, then verify that your order has been confirmed in the lab's submission system. If you have questions about specific requirements for your sample type, review the sample submission guidelines or contact the lab directly before you pack.

Careful preparation at the shipping stage protects months of upstream work and keeps your sequencing results on schedule.

What common mistakes delay NGS sample processing?

Even experienced researchers make packaging errors that slow down processing. The most frequent issues labs see include:

  • Incomplete or illegible label: Partial labels, handwritten identifiers that smear, or tubes labeled only with a generic descriptor like "RNA" create immediate confusion on arrival.
  • Loose samples in transit: Plates and tubes placed directly into a shipping box without padding or containment almost always arrive damaged or leaking.
  • Missing paperwork: Samples arriving without a confirmed order or project number require manual follow-up before they can enter the processing queue.

 

NGS Sample Shipping: Frequently Asked Questions

What concentration do NGS samples need to be?

NGS DNA and RNA concentrations vary depending on the application. Check our sample submission guidelines for the exact requirements for your specific assay.

Can I use Parafilm to seal my NGS sample tubes?

A small amount of Parafilm is acceptable for added security, but avoid wrapping tubes heavily. Over-sealing makes it difficult for lab staff to open samples quickly and can slow down processing. If your lab has specific sealing requirements, check the sample submission guidelines before you ship.

How should I label my NGS samples for shipping?

Every plate and tube must be clearly labelled before shipping, and the labels must match your sample submission form exactly. Use printed labels where possible, as handwritten labels can smear or become illegible during transit, especially with dry ice condensation. Include the sample name or ID on each individual tube.

How should NGS samples be packed for shipping?

Samples should be packed in racks with adequate padding and secondary containment to prevent movement or leakage in transit. Plates must be sealed with adhesive film and tubes must be firmly capped. Do not place samples directly in a box with dry ice without securing them in a rack or container first.

What paperwork is needed when shipping NGS samples?

You will need a completed sample submission form uploaded to the lab's system, and a printed copy of your submission receipt included in the box. Your project number should also be clearly included so the lab can match incoming samples to your order on arrival.
