DNA Testing Services We Offer

We offer twelve distinct DNA testing services to meet personal, legal, and government needs. Most tests use a non-invasive cheek swab collected on-site by a certified collector, a brief, straightforward procedure:

• Paternity: Determines whether a man is the biological father of a child. Available as a legal or non-legal test depending on whether results need to be presented in court or to a government agency.
• Court-Admissible: Follows strict chain-of-custody protocols for use in custody disputes, inheritance cases, child support proceedings, and other legal matters.
• Immigration: Proves familial relationships for USCIS visa, citizenship, or passport applications when documentary evidence alone isn’t sufficient.
• Maternity: Confirms the biological relationship between a mother and child. Common uses include adoption cases, hospital mix-ups, and immigration.
• Twin Zygosity: Identifies whether twins are identical (monozygotic) or fraternal (dizygotic), relevant for medical history and personal curiosity.
• Infidelity: Provides discreet analysis in situations involving a potential relationship breach.
• Genealogy/Ancestry: Verifies lineage, ethnicity, and genetic history for individuals tracing their family origins.
• DNA Profiling: Establishes a unique genetic profile used for personal identification, parentage documentation, or family records.
• Genetic Reconstruction: Proves a biological relationship when a direct sample from a parent isn’t available by using samples from other relatives.
• Adoption Testing: Helps adoptees or birth families confirm biological relationships and fill in gaps in family history.
• Forensic Services: Analyzes DNA evidence in criminal or civil cases to support investigations and legal proceedings.
• Lifestyle: Offers insight into genetic factors related to fitness, nutrition, and wellness through FastestLabs.

What to Expect at Our Azusa Location

The process is straightforward. Walk in during regular business hours or request an appointment online or by phone. At check-in, bring a valid government-issued photo ID. If your test is connected to a court order or immigration case, bring any relevant paperwork as well.

Legal vs. Non-Legal DNA Tests

One of the most important decisions before testing is whether you need a legal or non-legal DNA test. A legal test follows chain-of-custody protocols and produces results that are court-admissible or accepted by government agencies like USCIS. A non-legal test delivers the same accuracy but is intended for personal knowledge only and can’t be used in legal or immigration proceedings. If you’re unsure which applies to your situation, our team can help you figure it out before collection begins.

Sample Collection & Results

Most clients are called back within five minutes of arriving. Collection takes only a few minutes and involves a gentle buccal swab: no needles, no discomfort. A certified collector then handles the sample under strict chain-of-custody procedures and submits it for analysis. Results for most relationship tests are typically available in 2-3 business days.
