DNA testing requirements in California

California does not require a prescription or doctor's order for a DNA paternity test. Parentage is established either by both parents signing a Voluntary Declaration of Parentage, which is administered by the California Department of Child Support Services under Family Code sections 7570 to 7577 and must be witnessed by an authorized agency such as a birthing hospital, a local child support office or a registrar of births, or by court-ordered genetic testing under Family Code section 7550 and following. For a result to be used in a California court, the test has to be run by an accredited laboratory with a completed chain-of-custody form, which means collection happens at a certified site and every person tested shows government ID. A home kit answers the question privately but is not accepted for child support, custody or a birth certificate change. Call if you are not sure which one applies to you.

What to Expect at Your Appointment

DNA testing at our Lancaster, California collection site is straightforward, painless, and typically takes less than 30 minutes. Here is what to know before you visit 43839 15th St W.

Bring a Government-Issued ID

Adults bring a driver's license, state ID, or passport. Children under 18 do not need ID. A birth certificate is helpful for legal tests but not required for personal tests.

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 43839 15th St W in Lancaster 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 Lancaster, California 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 Lancaster, California 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 Lancaster, California?

TestMark DNA has a certified collection site at 43839 15th St W, Lancaster, California 93534. 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 California?

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 Lancaster?

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.

Does Lancaster have more than one TestMark DNA collection site?

Yes. Besides this site at 43839 15th Street West, near Avenue J-8, TestMark DNA has a second Lancaster collection site at 44725 10th Street West, Suite 240. Both are in the city of Lancaster in the Antelope Valley.
