Collecting Your DNA Samples with a Home Kit

Collecting DNA samples is done using our home sample collection kit. You will receive your DNA test kit with full instructions just a few business days after placing your order.

Please follow these visual examples for collecting your DNA samples. You need to repeat this process for for every person to be tested.

Instructions to Follow

Our DNA test kit contains oral swabs (also called “buccal swabs”). Watch our brief sample collection video to learn how to collect your samples or read the more detailed step by step instructions below.

Step 1

Remove the oral swabs from the plain envelopes in the DNA test kit.

Step 2

Once you have removed the swabs, the envelopes need to be filled in with some basic information. You also need to fill out the consent form you find inside the kit.

Step 3

With clean hands, proceed to rub firmly the swabs for about
1 minute inside the mouth against the cheek to collect saliva sample. This action should be firm but not aggressive and should not be uncomfortable. Remember to use all the swabs provided for every person.

Step 4

Allow the swabs to dry for an hour. Tip: You can place them upright in a clean glass. Once they are dry you can return them to their corresponding envelopes. Make sure that at no time do swabs from different people come into contact with one another.

Step 5

Once you have completed all previous steps, place the swab envelopes and the consent form into the larger pre-addressed envelope. Please remember to attach sufficient postage stamps and send your samples off for analysis. We recommend using courier or tracked mail service for traceability purposes.

Note: You can also collect your kit from one of our South Africa offices. We are based in Johannesburg and Cape Town. If you do wish to collect a DNA testing kit in person, you will need to contact us before to make an appointment.

A few pointers

  • Your DNA is not altered by medication, drugs, surgery or organ transplants.
  • Using blood for a DNA test is no more accurate than using saliva. This is because DNA is the same in every cell in our body.
  • Sample collection for a legal test is carried out in exactly the same way as explained above. However, a sampler is needed to collect the samples and ensure the chain of custody is followed.
  • It is recommended not to eat or drink for at least half an hour before samples are collected.

Collecting the samples is easy! What next to obtain my kit?
