Location Map
In Portland, Oregon, TestMark DNA collects samples at 501 North Graham Street, Suite 1203, the patient entrance address of Legacy Emanuel Medical Center in the Eliot neighborhood. Legacy's Public Parking Structure 2 is directly across North Graham Street.
501 North Graham Street is the address Legacy Emanuel Medical Center gives for its patient entrance, and it is also the address of TestMark DNA's site for DNA testing in Portland, Oregon, listed in Suite 1203. Legacy's campus map labels Medical Office Building 2 at 501 North Graham, with the primary entrance and valet stand on North Graham and Public Parking Structure 2 directly across the street; Legacy says parking is free. The hospital's primary address is 2801 North Gantenbein Avenue, so a map pin on Gantenbein lands on the same campus but a different door. The campus is in the Eliot neighborhood of North Portland, within a few blocks of the Interstate 5 ramps for Greeley Avenue and Swan Island and for I-405 and US 30 West.
TriMet lines 4 and 44 stop on North Vancouver Avenue at Knott Street, a couple of blocks from the Graham Street entrance, and line 24 stops at Vancouver and Fargo.

What to Expect at Your Appointment
DNA testing at our Portland, Oregon collection site is straightforward, painless, and typically takes less than 30 minutes. Here is what to know before you visit 501 N Graham St Suite 1203.
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 501 N Graham St Suite 1203 in Portland take under 30 minutes from check-in through sample collection, including the chain-of-custody paperwork completed in person.
Your Collection Is Scheduled by TestMark DNA
Collection sites in Portland, Oregon handle chain-of-custody (legal) tests ordered through TestMark DNA. We recommend scheduling your visit so everyone arrives prepared: call (866) 702-7644 and we'll confirm the right test, book your collection, and tell you what ID to bring.
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 Portland, Oregon 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.
Not Covered by Health Insurance
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 Portland, Oregon?
TestMark DNA has a certified collection site at 501 N Graham St Suite 1203, Portland, Oregon 97227. We schedule chain-of-custody (legal) collections here for you, 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 Oregon?
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 Portland?
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.
