We do not sell or distribute any of your private information, including your DNA profile. We only use your testing information in order to provide you the services you have requested, process your order, and respond to any order or billing related questions.

See our Privacy Policy

We DO NOT sell any of the information obtained for the testing to any third parties.

See our Privacy Policy

We do not test the DNA for additional markers other than those to generate the DNA Profile, which is provided to the client. We do not sell any data to third parties.

See our Privacy Policy

Once the testing is completed and results are provided to you, we save your raw DNA data in your account. You can request us to destroy your raw data at any time. Be assured your data will never be provided or sold to a third party.

At this time, kits are available for purchase in the UK through online transactions only. 
  1. We mail you a kit
  2. You collect DNA samples and return them to the lab
  3. When samples are received at the lab, processing and testing begins
  4. As soon as we have completed the analysis, you will receive an email indicating you can go online to retrieve your results in My Account.

Once your kit arrives and you've collected your DNA samples and returned them to us in the pre-paid postage envelope, please allow time for testing. Each test has its own processing timeline (which can be viewed on this website) in that test’s Overview section. 

  1. Visit and add the desired product to the cart

  3. Complete the checkout steps as instructed 

Please send an email to and provide us with detailed information so we can look up your account and correct the problem. Please include your promo code/voucher number and your order-reference number.

Yes. You are automatically directed to a thank-you page after your purchase is complete. You also receive a confirmation email immediately.

All DNA tests are performed in a highly-accredited laboratory, though not all tests are processed at DDC. For details, see kit instructions for your specific product. 

You can check your order-status and results-status at any time in My Account.

Unfortunately, a small percentage of samples do not contain enough cheek cells to complete the test. If this occurs, you will be contacted to resubmit another sample at no charge and consequently, your results will be delayed. Therefore, to minimize turn-around time, getting a good sample the first time is important. Please carefully review the DNA collection instructions included in your kit

Genetics Basics

DNA (deoxyribonucleic acid) is a long molecule that is in almost all of our cells in the nucleus. It is the DNA that contains the body’s unique genetic information or ‘blueprint’. The molecule is a helix that resembles a twisted ladder. The information in DNA, stored as a code, is made up of four nitrogenous chemicals or ‘bases’: adenine (A), guanine (G), cytosine (C), and thymine (T). It is the order of these bases in genes that determines the information for building and maintaining an organism.

DNA bases always pair up with each other in the same way: A with T and C with G, to form units called base pairs. Base pairs form the ‘rungs’ of the DNA ladder while the vertical supports are composed of nucleotides.

DNA can replicate itself and each strand of DNA in the double helix can serve as a pattern for a duplicate sequence of bases. Duplication critical when cells divide because each new cell needs to have an exact copy of the DNA in the old cell.

Chromosomes are long DNA strands packaged into thread-like structures and located in the nucleus (core) of each cell. Each chromosome is made up of DNA tightly coiled around proteins called histones.

A gene is a distinct sequence of DNA bases that forms the core unit of information that determines what characteristics every living creature has. Genes, inherited from both parents, are found on the chromosomes.

Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all individuals, but a small number of genes vary slightly from person to person. These variations are what contribute to each person's unique physical features and tendencies. Your genes contain instructions for building everything about you: your eye, hair, and skin color, your tendency to gain weight, your athletic tendencies, your other unique characteristics, and more.

Humans inherit 23 chromosomes from each of their parents. Sperm and eggs cells each contain 23 chromosomes, which combine during reproduction to give the offspring a total of 46. Forty-four of these chromosomes are identical in men and women - the autosomes. The remaining two are called sex chromosomes, and are designated X and Y. Women inherit two X chromosomes and men inherit one X-chromosome from their mother and one Y-chromosome from their father. The genetic information we inherit is never exactly the same as that of our parents. During the production of egg and sperm cells, the chromosomes exchange segments in a process known as recombination, which produces new combinations of genes. These gene combinations give us similarities to our mother and our father but are a new mosaic of our maternal and paternal genes.

Each gene is made up of a series of bases (a nitrogenous molecule), which provide instructions for making a single protein. Any change in the sequence of bases creates a change in the instructions - known as a mutation. Some mutations have little or no effect on the protein, while others may cause the protein not to function at all. A genetic mutation is a permanent change in the DNA sequence that makes up a gene.

Mutations can occur in many places in the genome and have various effects depending on where they happen. Hereditary Mutations, ones that pass from parent to child are present throughout a person's life in virtually every cell in the body.

Mutations that occur only in an egg or sperm cell, or just after fertilization, are called new (de novo) mutations and may explain genetic disorders in which an affected child has a mutation in every cell, but has no family history of the disorder. Acquired mutations occur in the DNA of individual cells at some time during a person's life. These changes are caused by environmental factors such as ultraviolet radiation from the sun.

Acquired mutations in cells that are not eggs or sperm cannot be passed on to the next generation. Some genetic changes are very rare while others are common. Genetic changes that occur in more than 1 percent of the population are called polymorphisms. They are common enough to be considered a normal variation in the DNA. Polymorphisms are responsible for many normal differences between people such as eye color, hair color, and blood type.
