How it works

How at-home testing works

Choose the appropriate test, receive the collection kit, follow the instructions, return the sample to the stated laboratory, and receive your report after processing. The exact sample type, activation steps, and turnaround time depend on the product ordered.

Person reviewing an at-home genetic testing report in Canada
Testing is informational, not emergency care. Pharmacogenetic findings should be discussed with the prescribing doctor or pharmacist before any medication change. Microbiome findings describe the submitted sample and should not be treated as a diagnosis or complete explanation of symptoms.

At a glance

What to understand before ordering

The broad process is similar across products, but the collection method, laboratory, report format, and expected processing time can differ.

Choose by report scope

Confirm that the selected test addresses your actual question. A pharmacogenetic report, wellness DNA report, predisposition test, and microbiome test provide different information.

Follow the exact kit

DNA tests commonly use an oral or cheek-swab collection, while a gut microbiome test uses a stool sample. Always follow the instructions included with your specific kit.

Count time from lab receipt

Laboratory turnaround begins after an acceptable sample reaches the correct laboratory, not when the order is placed or when the kit is delivered.

Before checkout

Start with the right test

The first decision is not how to collect the sample. It is whether the product’s report matches the question you are trying to answer.

  • Review the genes, medications, conditions, traits, or microbiome categories included.
  • Check the required sample type and whether online kit activation is required.
  • Review the regular product price, shipping, taxes, and possible return-postage costs.
  • Confirm the estimated laboratory turnaround for the individual product.
  • Plan appropriate professional follow-up for medication or health-related findings.

The complete sequence

Six steps from order to report

These steps apply to most online orders. Product-specific instructions always take priority.

Select the product

Read the product description and choose according to report scope—not price or test name alone. Contact support before ordering when you are uncertain about product coverage.

Complete checkout

Enter an accurate delivery address and contact information. Review the final cost, consent requirements, shipping method, and relevant refund terms before payment.

Receive and inspect the kit

Check that the package matches the test ordered and contains the expected collection materials. Contact support before collecting if anything is damaged, missing, or unclear.

Activate when required

Some products require the customer to activate or register the kit through a laboratory portal. Complete that step before returning the sample when the instructions require it.

Collect and return the sample

Follow the collection, labelling, packaging, storage, and return instructions exactly. Use the return address provided with the specific kit.

Receive and review the report

Reports are generally delivered electronically or through a laboratory portal. Review the report’s scope and limitations before using it in a health, medication, or nutrition discussion.

Collection paths

DNA testing and microbiome testing use different samples

Do not assume that the preparation and return steps are interchangeable.

DNA and pharmacogenetic pathway

Oral or cheek-swab collection

Many health and lifestyle DNA tests use a non-invasive oral or cheek-swab sample. The exact device and preparation steps depend on the selected product.

  • Read preparation instructions before opening the collection materials.
  • Label the sample exactly as directed.
  • Allow swabs to dry when the kit instructions require it.
  • Complete consent and activation steps before return.
  • Do not change medication based only on the report.
Gut microbiome pathway

At-home stool-sample collection

The gut microbiome test uses a stool sample. The report reflects the submitted sample and may include information about bacterial composition and dietary considerations.

  • Read all instructions before opening the sample components.
  • Use only the supplied collection materials.
  • Avoid contamination with water, urine, cleaning products, or other material.
  • Seal and package the sample exactly as instructed.
  • Return it promptly using the address included with the kit.

Timing

Typical laboratory turnaround examples

Shipping time is separate. These estimates start after the correct laboratory receives an acceptable sample and all required information.

Current documented processing estimates by test
Test Sample or process note Estimated laboratory turnaround
Caffeine Sensitivity DNA Test Kit-based DNA collection 5–7 working days
Alcohol Metabolism DNA Test Kit-based DNA collection 5–7 working days
Longevity Test Kit-based DNA collection 5–7 working days
DNA Methylation Test Oral-swab collection Approximately 10 days
Genetic Predisposition Disease Test Swab sample 14–21 working days
Gut Microbiome Test At-home stool sample 15–20 working days
KnowYourself DNA Test Portal activation and portal-based status/results may apply 30–45 working days

Processing times are estimates and can change. Recollection, quality-control review, missing activation or consent, incomplete information, holidays, or laboratory workload may extend the timeline.

After laboratory receipt

What happens while the sample is processed

The laboratory checks the sample and associated information before analysis. A sample may be delayed or rejected when it is incorrectly labelled, contaminated, damaged, insufficient, expired, returned to the wrong address, or missing required activation or consent.

When a sample cannot be processed, the next step depends on the reason. A recollection may be arranged. Additional kit, shipping, or repeat-testing fees may apply when the issue results from collection, storage, labelling, or another cause outside laboratory control.

How to use the finished report responsibly

A pharmacogenetic result is one part of a medication decision. The prescribing professional may also consider diagnosis, symptoms, dose, age, kidney or liver function, pregnancy, allergies, interactions, other medicines, and clinical history.

A microbiome result is an educational snapshot of the submitted sample. Diet, recent antibiotics, illness, travel, routine, and other factors may affect the microbiome. Persistent or concerning symptoms should be discussed with a qualified healthcare professional.

Frequently asked questions

Questions about the testing process

Review the product page and kit instructions whenever a general answer differs from a product-specific requirement.

When does the laboratory turnaround begin?

It begins after the correct laboratory receives an acceptable sample and any required consent, activation, participant information, and payment are complete. Kit delivery and sample-return transit are separate.

Does every test use a cheek swab?

No. Many DNA tests use an oral or cheek swab, but the gut microbiome test uses a stool sample. Use only the sample type and materials supplied for the product ordered.

Is return postage included?

Do not assume it is included. Review the checkout, product information, and kit instructions. Return arrangements and costs may vary by product and laboratory.

Can I send every sample to the same address?

No. Different tests may use different laboratories or return locations. Always use the address supplied with the specific kit.

What happens if my sample is inadequate?

Support or the laboratory will explain whether recollection is required. Fees may depend on why the sample could not be processed and the terms of the selected test.

How will I receive my results?

Reports are generally provided electronically. Some products use a laboratory portal for kit activation, status updates, and report access. Follow the instructions supplied with your product.

Can I change medication after reading a PGx report?

Do not start, stop, replace, or change the dose of a prescription based only on the report. Discuss medication-related findings with the prescribing doctor or pharmacist.

Does the process work across Canada?

The general order-and-return process is available across Canada, but delivery and return timing may differ for remote, northern, or hard-to-service locations. Review shipping details before ordering.
