Returning DNA Sample to the Lab

As of December 2014, 23andMe is now using local post for inbound and outbound shipping to addresses in the EU. 

For shipments with local post, the kit came with the prepaid shipping label affixed on the bottom of the box. As indicated in the kit instructions, make sure you have completed the registration process and replaced the funnel lid with the screw-on cap prior to packaging your sample for shipment.

Your saliva sample is stable at a wide range of temperatures once it is mixed with the DNA stabilization buffer liquid, but we recommend that you ship your collected sample to the laboratory at your earliest convenience.


The transportation supplies for your saliva sample are included in your kit. Simply place the collection tube containing your sample in the plastic specimen bag, and then place the bag directly into the box. The plastic clamshell should be discarded. Remove the adhesive strip on the kit flap and seal the kit.


Drop the kit off at your nearest local post mailbox. 

Note: The distribution center will only accept samples delivered via the prepaid shipping materials we provide in your order. Do not attempt to drop off your sample directly at the distribution center or mail it directly to our lab as this may cause delays in transit and in analysis.

Your sample will first be shipped to our distribution center in Oss, Netherlands via local post, and then forwarded to our lab in North Carolina via FedEx.
