What to Expect at Your Appointment
DNA testing at our Seattle, Washington collection site is straightforward, painless, and typically takes less than 30 minutes. Here is what to know before you visit 550 17th Ave Ste 200.
The Sample Is a Painless Cheek Swab
Collection takes about a minute. A trained technician rubs a soft cotton swab on the inside of the cheek for each tested party. No needles, no blood, no fasting required.
Plan for 15–30 Minutes on Site
Most visits to 550 17th Ave Ste 200 in Seattle take under 30 minutes from check-in through sample collection. Legal tests run slightly longer because chain-of-custody paperwork is completed in person.
Walk-Ins Welcome (Call Ahead to Confirm)
Appointments are not required at most Seattle, Washington collection sites. Calling (866) 702-7644 before you arrive lets us confirm current wait times and the right test for your situation.
Children Can Be Tested at Any Age
Infants, toddlers, and minors are all eligible. The cheek swab is the same regardless of age. For legal tests involving a minor, the custodial parent or legal guardian must be present to sign the chain-of-custody form.
Results Arrive in 3–5 Business Days
Once all samples are received at the accredited laboratory, standard turnaround is 3 to 5 business days. Results are delivered confidentially by encrypted email or secure portal. They are never released over the phone.

Pricing & Payment
DNA test pricing in Seattle, Washington depends on the specific test you need. Call TestMark DNA for a free consultation. We will confirm the exact price for your situation before you visit the collection site.
Pricing Varies by Test Type
Paternity, maternity, sibling, grandparent, immigration, and home kit tests are each priced differently. Legal (court-admissible) tests cost more than personal-knowledge tests because they include chain-of-custody documentation.

DNA paternity and relationship testing is classified as a non-medical test and is not reimbursed by health insurance plans. Payment is collected directly at the time of testing.
Free Consultation
We walk you through pricing on the phone before you commit. There is no charge to call, no charge to ask questions, and no obligation to book a test after the consultation.
Discounts for Multiple Parties
Tests that involve additional parties (for example, a paternity test that also includes the mother, or sibling tests with multiple siblings) often qualify for a per-person discount. Confirm by phone before your appointment.

Frequently Asked Questions
Where can I get a DNA paternity test in Seattle, Washington?
TestMark DNA has a certified collection site at 550 17th Ave Ste 200, Seattle, Washington 98122. No appointment is needed and results are typically returned in 3 to 5 business days.
Do I need a doctor's order or court order for DNA testing in Washington?
A doctor's order is generally not required. However, if you are a New York State resident, a prescription, court order, or ordering by other authorized persons is required by state law for all DNA identity or relationship tests.
Can DNA testing be done without the mother present?
Yes. A DNA paternity test can be performed without a sample from the child's biological mother. Including the mother's sample is preferred when possible as it improves accuracy.
How long do DNA test results take near Seattle?
Results for a standard DNA paternity test are typically returned within 3 to 5 business days from when all samples are received at the laboratory.
Is DNA testing confidential?
Yes. All samples are packaged in tamper-proof bags and processed at an accredited laboratory with restricted access. Results are shared only with authorized individuals and are never released over the phone.
What type of sample is collected for a DNA test?
The standard sample is a buccal swab - a cotton swab rubbed gently inside the inner cheek. It is painless, non-invasive, and provides the same accuracy as a blood sample.
Will DNA test results be accepted in court?
Results from a legal DNA paternity test performed at an accredited facility may be accepted in court, provided the chain-of-custody form was completed according to laboratory guidelines. Non-legal test results are not intended for court use.
Is DNA paternity testing covered by health insurance?
DNA paternity testing is considered a non-medical test and is not covered by health insurance plans.
