What is a whole genome sequencing (WGS) test?

While whole exome sequencing tests will analyze all of the portions of DNA responsible for producing proteins, it only accounts for 1% of a person's DNA. Researchers have found that DNA changes outside of this 1% can produce symptoms and conditions even though they do not code for proteins. With a whole genome sequencing (WGS) test, we analyze all of the base pairs of a person's DNA - about ~3.2 billion - to try and find a cause for any symptoms or conditions.

Because we look at so many more base pairs, the potential diagnostic yield of a WGS test is higher than whole exome sequencing tests.

Dried blood spot (DBS) cards are preferred for WGS, but acceptable are saliva or buccal.

When should I order a WGS test?

Unlike WES, WGS sequences genes as well as regions outside of genes. Therefore if a patients symptoms are broader, and less defined and/or you have had a lot of testing done with no answers or simply want to start with the most comprehensive sequencing test we have, this may be a good option. Please refer to our recommendations section for further guidance.

Included with your purchase:

Simple and easy self-collection kit
All the shipping supplies and documentation needed
Accredited sample processing and analysis pipeline
30 min post-test counsellor session

Whole Genome Solo:

For sequencing just one individual to find a rare disease

Whole Genome Duo:

For sequencing one individual plus one parent to determine if there is a disease that is inherited - for a number of cases, this can help narrow down whether a particular DNA change is inherited or not (this option is used if only 1 parent can provide a sample)
For pre-pregnancy carrier-screening in a couple (using samples from both members of the couple considering having children)

Whole Genome Trio

For sequencing one individual plus both parents to determine if there is a disease that is inherited

Results are typically ready within 3-5 months, once received in the laboratory, unless unexpected circumstances arise. These circumstances will be communicated as soon as possible. We reserve the right to limit quantity of orders purchased. Please contact for bulk purchasing options.
We take pride in performing the adequate quality control measures and taking the steps necessary to ensure that our lab’s protocols actions and procedures are trackable and ultimately provide you with a test result that you can trust.

1. If you cancel your order before we ship your sample collection kit: If you request a refund after placing your order, but before our Sample Coordinator ships you your sample collection kit, we will provide you with a full refund less a small service charge.
2. If you cancel your order after we ship you your sample collection kit: If you request a refund after your sample kit is shipped to you, OR after you ship back the collection kit, we will provide you with a full refund less shipping and collection kit costs, and a small service charge

If you have any questions about our refund policy, please contact us at info@discoverydna.ca.
We recommend a pre-test consultation, where a genetic counsellor will consult on things you are concerned about (e.g., chronic pain, seizures, or other widespread symptoms), and use that information to make a recommendation on the most appropriate test, and approach to finding any gene variants that could potentially be affecting those concerns. We will then conduct a post-test consultation, which is included in the cost, to assist in understanding the results.
