Quick answers before ordering
What most customers want to know first.
These details often determine whether a test is suitable, so it is worth checking them before checkout.

How long can results take?
Processing times vary by analysis. The laboratory timeline generally begins after the sample is received and accepted, not on the order date.

How accurate are DNA tests?
Accuracy depends on the test method, sample quality, laboratory process, and the question being asked. An accurate result can still have limits in how it should be interpreted.
Understand test accuracy
Simple ordering workflow
How the DNA testing process usually works.
Exact instructions vary, but most orders follow the same basic path from test selection to report delivery.
- Choose the correct test type Confirm the purpose of the test, the sample method, and whether you need an informational result or a documented legal process.
- Collect and return the sample Use the materials supplied with the kit, follow the collection directions carefully, and send the sample to the listed return address.
- Laboratory processing begins After the sample is received and accepted, the laboratory completes the selected analysis. Timing differs by test.
- Review the report in context Read the scope and limitations of the report before making health, breeding, or documentation decisions.

Frequently asked questions
Answers to common DNA testing questions.
Use these quick answers as a starting point, then review the relevant product page before ordering.
Which DNA test should I choose?
Start with your goal. A health-focused genetic report, a pet breed test, an inherited disease screen, and a legal identity test are not interchangeable. Compare the intended use and sample requirements before ordering.
Can I collect a DNA sample at home?
Many informational tests support at-home collection, often with an oral or cheek swab. Some tests use a different sample, and legal testing may require supervised collection and identity verification.
When does the result timeline begin?
The processing timeline usually begins after the laboratory receives and accepts the sample. Shipping time, sample quality, and the type of analysis can affect the total time from order to report.
Can a health DNA test diagnose a condition?
A genetic result may provide information about a tested variant or susceptibility, but it should not be treated as a diagnosis by itself. Health concerns should be discussed with a qualified healthcare professional.
What makes a legal DNA test different?
Legal testing generally requires documented identity checks, controlled sample collection, and a recorded chain of custody. A private at-home test may not meet those requirements, even when the laboratory analysis is reliable.
