Returning your sample to the lab

Important: You must provide your sample and return your collection kit from the same country to which your kit was shipped by 23andMe.

If you are mailing your sample within the United States, your kit came shrink-wrapped with the prepaid shipping label affixed on the under-side of the box.

Before preparing your sample for shipment, you will need to register your sample collection tube and replace the funnel lid with the screw-on cap. 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.


For US customers, drop the package off at any US Postal Service Mail Box if shipping from within the United States. The box is already pre-addressed and pre-paid. For international return shipments, please refer to the shipping instructions included with your kit. No other personal information is required for the analysis.

Note: To protect the privacy of all customers, the lab will only accept samples delivered via postal service or carrier. Do not attempt to drop off your sample directly at the lab.

A return tracking link will be available from the sample status progress bar on your profile homepage. You may also choose to note the return tracking number located on the bottom of the shipping label:
