Immigration DNA Testing in Tempe

Local, Certified Collection for Visa & Citizenship Petitions

When USCIS, a U.S. Embassy, or a passport agency needs biological proof of a family relationship, immigration DNA testing is the only non-documentary method they accept. The stakes are real: delays or errors at the collection stage can slow a family reunification petition or put it at risk. At Fastest Labs of Tempe, our certified collectors handle every step with the precision and confidentiality your case demands.

We serve petitioners throughout the Tempe area from our local, staffed facility. Results are legally admissible and upheld throughout all of the U.S., and most are available within 2-3 days, dependent on test type.

Walk-in appointments are welcome, and same-day scheduling is available. Call (480) 418-6156 to get started or to ask any questions about the process.

Relationship Types We Test for Family-Based Immigration

USCIS or a consular officer may request DNA testing when primary documentary evidence, such as birth certificates, is insufficient or unavailable to prove a biological relationship. We handle paternity/maternity testing and full or half siblingship testing for family-based immigration petitions. Results support visa applications, citizenship petitions, and passport verification.

What to Know Before You Schedule

The most commonly tested relationships are parent-child (paternity or maternity) and siblingship. More distant relationships may not be reliably established through DNA, so confirm with USCIS which relationship type your case requires before scheduling. Testing is voluntary, but declining when requested may result in denial of the petition. For parent-child cases, results must report a probability of relationship of at least 99.5% to be considered conclusive by U.S. immigration authorities. Sibling testing is evaluated under different standards, so confirm the applicable threshold with the requesting agency for your specific case.

Families with Members Outside the U.S.

For families with members in different countries, we offer pre-arranged sample collection locations for individuals outside the U.S. The petitioner’s sample is collected here in Tempe, and the beneficiary abroad typically provides their sample at the U.S. Embassy or Consulate in their home country.

Why Lab Selection Matters for Immigration DNA Testing

USCIS and the U.S. Department of State require immigration DNA testing to be performed by a laboratory accredited by the AABB (the Association for the Advancement of Blood and Biotherapies). Results from non-accredited facilities can be rejected, meaning petitioners may need to repeat the test at their own expense.

AABB accreditation requires rigorous chain-of-custody documentation, identity verification at collection, and qualified laboratory staff. The accredited laboratory sends results directly to the appropriate USCIS office, U.S. Embassy, or Consulate, and petitioners also receive a copy of the report. Choosing a reliable, locally accessible collection point in Maricopa County reduces scheduling friction and supports the chain-of-custody standards your case depends on.

What to Expect During Sample Collection

The collection process at Fastest Labs of Tempe is straightforward. Our certified collectors use a non-invasive buccal swab (a simple cheek swab) to collect your sample quickly and painlessly. Each party’s identity is verified at collection and documented as part of the chain-of-custody record, which protects the integrity of your results from collection through delivery. All specimens are handled with a secure chain of custody, and results are released only to authorized parties with strict confidentiality. Most results are available within 2-3 days, dependent on test type.

How to Prepare for Your Appointment

Avoid eating or drinking anything except water for at least 30 minutes before your appointment. Bring a valid government-issued photo ID. If USCIS or an embassy sent you a letter or Request for Evidence initiating the test, bring that document as well. It helps us start the process correctly on your first visit.

Common Questions About the Process

The petitioner (U.S.-based) and the beneficiary (abroad) don’t need to be tested at the same location or at the same time. Once your sample is collected in Tempe, the accredited laboratory can coordinate the overseas portion of the collection. Results go directly from the laboratory to the requesting USCIS office, U.S. Embassy, or Consulate. You’ll receive a hard copy of the report once the test is paid in full.

Immigration DNA testing isn’t covered by health insurance, and all costs are the responsibility of the petitioner and/or beneficiary. If your case involves a complex situation, such as individuals born abroad without citizenship, our team can walk you through what’s needed before you come in.
