How to collect your DNA sample at home

To collect your cheek swab DNA sample at home, simply follow the instructions included in your test kit to collect your sample and return it to our accredited laboratory for analysis.

Here, we explain the home DNA sample collection process in more detail, so you can collect your samples quickly and easily, for an accurate result.

What do you need to collect a DNA sample?

Each AlphaBiolabs DNA testing kit contains:

• Complete, easy-to-follow instructions on how to collect your cheek swab samples and return them to our laboratory
• A pre-addressed envelope to send your samples back to us
• Collection swab packages each containing one swab
• Individual DNA test sample envelopes for each person being tested

You also need a clean place to collect your samples, and a pen to write your details on the front of the swab envelope.

How do you collect your DNA sample at home using a swab?

It’s important that your samples are collected properly, as incorrect sample collection will delay your test results.

We recommend collecting one person’s samples at a time to avoid any mix up.

Please DO NOT eat or drink anything immediately before collecting your samples.

1. Complete the information required on the swab envelope BEFORE inserting the used swab.
2. Using the swab provided, firmly rub on the inside of each cheek for at least 20 seconds and then immediately put the used swab into the swab envelope.
3. Seal the swab envelope and check that all the details on the front have been completed.
4. Repeat these steps for each person taking part in the test, using a separate swab and envelope for each person.

Every person taking part in the test must also register their test by completing an online registration and consent form. Simply follow the instructions in your kit to register your test.

You will not get your results if you do not register your test samples online.

Do’s and don’ts when collecting your cheek swab DNA samples

DO

• Wash your hands before you collect your sample
• Remove any lipstick/lip gloss before collecting your sample
• Put your swab straight into the sample envelope after collecting your sample
• If collecting someone else’s sample, hold the swab stick as far away from the swab end as possible
• Send your samples back to the laboratory as soon as you have collected them

DON’T

• Eat or drink 30 minutes before collecting your sample – residual food on the swabs can cause mould or bacteria to grow, which can interfere with the test
• Remove the swab from the sterile packaging until you are ready to collect your sample
• Collect your sample from an area other than the inside of your cheek
• Put your swab on a surface before or after sample collection
• Put the swabs in plastic or sandwich bags before putting them into the sample envelope. The plastic stops the swabs from drying out, which can encourage microbial growth, and degrade the DNA

How do you make sure your DNA sample isn’t contaminated?

To protect your sample and ensure accurate test results:

• Avoid eating, drinking, smoking, or chewing gum for at least 30 minutes before taking your swab.
• Do not share or reuse swabs between people.
• Keep swabs in their packets until you are ready to collect the sample.
• Avoid touching the swab tip or letting it touch any surface.
• Seal envelopes straight away after placing the swab inside.

Following these steps helps prevent cross-contamination, ensuring your results are clear and reliable.

How are the swabs used for DNA testing?

Once your swab arrives at AlphaBiolabs’ accredited laboratory, our scientists:

1. Extract the DNA from the cheek cells collected on the swab.
2. Analyze and compare genetic markers between the tested samples.
3. Generate a clear, accurate DNA test report.

How do you return your DNA samples?

Once you have collected your cheek swab samples, simply mail them back to our laboratory using your preferred shipping method.
