Start from the problem you are trying to solve

A useful DNA test begins with a specific question. The test type, sample method, reporting format, and collection requirements should all support that question.

You want wellness-oriented genetic information Begin with the health testing category, then compare the individual test purpose and reporting scope.
You want breed or inherited-condition insights for a pet Choose the pet category, species, and specific answer you need instead of selecting only by the number of markers.
Your results may be used for a formal purpose Confirm whether identity verification, supervised collection, documentation, or chain-of-custody procedures are required.

What customers usually need to know first

How is the sample collected?

Collection may involve a cheek swab, oral sample, hair, blood, or another sample type, depending on the selected test.

How long will the results take?

Processing time depends on the test, sample quality, laboratory workflow, and when the returned sample is received.

Which test is the right one?

Start with your question, confirm the report scope, and check whether collection or documentation requirements apply.

The usual process

How DNA testing generally works

Exact instructions vary by test. Always follow the collection and return directions supplied with your selected kit.

Select the appropriate test

Confirm that the test answers your intended question and review the sample, reporting, privacy, and documentation details.

Collect and return the sample

Follow the instructions carefully, label the materials as directed, and return the sample using the method provided.

Review the completed report

Processing begins after the sample is accepted. Results and supporting information are then provided using the applicable system.

DNA testing questions

Frequently asked questions

Review these common questions before choosing a health-focused, pet, at-home, or documented DNA testing workflow.

How do I choose the right DNA test?
Begin with the exact question you want the test to answer. Then compare the intended purpose, sample type, report contents, processing expectations, and any collection requirements. You can also review the test comparison page.
Can every DNA test be completed at home?
No. Many informational tests may offer at-home collection, but certain formal or documented testing situations may require identity verification, witnessed collection, or a chain-of-custody procedure. Review the legal chain-of-custody guide before ordering for a formal purpose.
How long do DNA test results usually take?
Timelines vary by test and normally begin after a usable sample is received and accepted. Sample quality, laboratory workflow, and the type of analysis may affect the completion date. See the results timeline guide.
Are DNA test results always a medical diagnosis?
No. Many health-focused genetic reports are informational and are not a diagnosis. Results should be interpreted within the stated test limitations and discussed with a qualified healthcare professional when medical decisions are involved.
When does laboratory accreditation matter?
Accreditation and documentation requirements depend on the type of testing and how the results will be used. Formal relationship or legal testing may have requirements that do not apply to wellness or pet DNA tests. Review the AABB laboratory information or contact uDNA before ordering.
How much does a DNA test cost?
Pricing varies according to the test type, analysis scope, sample method, and documentation requirements. Review current options on the pricing page or read the DNA test cost guide.
