Everything you need to hand out a 3X4 kit with confidence.

The Provider's Guide to 3X4 DNA Sample Kits and kit registration: what's in the kit tube, why the kit code has to be registered, and the exact steps for registering as a practitioner or assisting your client to register themselves.

Updated August 13th, 2026

Kit contents

One box, one cheek swab, one report.

Each 3X4 Sample Kit includes everything one person needs to complete a simple, painless cheek swab. The collection vial stabilizes the cell sample in a non-toxic buffer while it ships to our laboratory. After the DNA is extracted, it undergoes genotyping to produce a personalized 3X4 genetic report.

3X4 DNA Sample Kit contents: swab, vial, sealable bag, cardboard tube and shipping bag — Shipping bags are not included in all kits.

Storage & stability

Every 3X4 Kit has an expiration date at least 12 months from when you receive it. Do not use a kit if the swab or vial has passed its expiry date.

Ambient temperature only

Store kits and collected DNA samples at ambient temperatures between 59–86 °F (15–30 °C).

Warnings & precautions

See the safety data sheet at 3X4genetics.com/sds for full handling information.

Kit code

A kit code is anonymous until someone registers it.

Registering the unique kit code via 3X4's secure platforms is a required step for every 3X4 test. Until the kit code is registered, it is not linked to any person's identity.

Unregistered samples may be discarded

Samples that reach the lab without a registered kit code cannot be identified and may be discarded.

Find the kit code

Each kit includes a unique Kit Code printed on the label of the DNA sample collection vial. That code tracks the sample and genetic results through storage, transit and lab processing, which is what keeps the sample unidentifiable to unauthorized personnel.

The kit code → report identity chain

The client deposits their sample into the vial, labelled with a unique kit code.

The kit code is linked to the client's profile (name, email, etc.) when the kit is registered.

The kit code is used to identify the sample and genetic results at the lab.

3X4 links the lab's genetic results back to the client's profile, so an identifiable report can be generated.

Two ways to register

Who registers the kit, you or your client?

Either the client registers their own kit by following the instructions in their kit, or you register it for them from your 3X4 practitioner portal. Only one of the two is needed.

Option A

Client registration

Using the instructions provided inside the 3X4 Kit, clients register their own kit code, link their results to your practitioner profile, and unlock the sample collection instructions.

See the client steps

Enter Your Serial Number screen on a phone

Option B

Practitioner registration

Practitioners can register a client's kit directly from their 3X4 practitioner portal account, linking the client, the kit code and the practitioner in one flow.

When your client registers their own kit

Client kit registration, step by step.

If your client was shipped a kit from August 13th, 2026, their kit insert will instruct them to scan the QR code on the bottom of the kit, or visit 3X4genetics.com/register-kit.

Step 1

Enter Serial Number

The client enters the serial number printed on the outside of the 3X4 kit tube, or scans the QR Code. On-screen guidance shows exactly where to find it, with example formats.

New accounts must verify their email address.
A person can only register their own kit.
Only one kit can be registered per profile; a second kit needs a new profile.

Kits shipped prior to August 13th, 2026 have different instructions

See the instructions for older 3X4 kits:
Instructions for older 3X4 kits

Enter Your Serial Number screen — Enter your serial number

STEP 2

Claim Kit

Clients who received their kit from your practice will see a claim kit screen prompting them to create an account with their own email address.

A kit can only be registered to one email address and account

The client must provide the email address the kit will be registered to. Their results account will be tied to this address.

Step 3

Enter Verification Code

A 6-digit code is sent to the client's email. Entering it proves they control the address before registration continues.

Step 4

Create Account

With the email verified, the client creates their account. They review and accept the Terms of Service and Privacy Policy, set a password, and confirm consent before continuing.

Step 5a

Select DNA Kit

Shown only when the client has multiple kits.
The client selects the physical kit in their possession from their unregistered kits, matching it to the serial number on the tube. A confirmation prompt double-checks the selection.

Manage Your DNA Kits screen — MANAGE YOUR DNA KITS

Step 5b

Choose Recipient

The client chooses who will use the kit: Myself, or Someone Else.

The account holder can only register their own kit

If the sample will be collected by anyone other than the account holder, they must choose Someone Else. The client can only register their own kit through their own account.

Who is This Kit For? screen — Who is this kit for?

Step 5c

Transfer Kit to Someone Else

Choosing Someone Else lets the client transfer the kit by entering the recipient's email address. The recipient receives a secure link and completes registration under their own account.

Step 6

Personal Information

The client enters their name, phone number, date of birth, sex assigned at birth, and biological ancestry information. Sharing their biological ancestry is optional, but will allow us to tailor future versions of their report.

Step 7

Enter Kit Code

The client enters the kit code from the DNA sample collection vial packed inside the kit (format KUSA000000).

Enter Your Kit Code screen — Enter your kit code

The kit code is how your client's sample will be identified at the lab

The lab only scans in the kit code on the DNA sample vial. The serial number on the outside of the tube is no longer required.
3X4 recommends you do not use the kit code and identifying information in the same communications. Learn more at Customer Privacy at 3X4 Genetics.

Step 8

Confirm Linked Practitioner

Clients who were shipped a kit, or whose kit is linked to your individual 3X4 account, will see your name pre-filled and fixed. By continuing, they consent to share their genetic test results with you.

Linked practitioner can't be edited

Clients may ask why they can't change the practitioner, so explain that their kit is linked to your practice. If the named practitioner is wrong, stop and contact 3X4 support.

Linked Practitioner screen — Linked practitioner

Step 9

Track sample return

Optional

The client captures the return tracking number printed on the shipping bag label, if one was supplied.

Biological sample shipping regulations apply

Samples ship as Exempt Human Specimens. Make sure 3X4's packaging instructions are followed.

Registration Complete

The client is taken through the next steps: collecting their DNA sample and shipping their sample to the lab for processing (results in 2-4 weeks from arrival at the lab). Remind your client to carefully follow the instructions provided.
