Types of DNA Tests We Offer

Every person who contacts us comes with a different concern, and there is no single test that fits every situation. Our lab offers several categories of DNA testing and genetic testing, so we can help match your needs with the right option. When you call, our team can walk through your reason for testing and discuss which approach may be suitable.

Common categories of testing we can discuss with you include:

• Relationship testing, such as paternity, maternity, and broader kinship analysis
• Personal knowledge testing, for clients who want answers for their own understanding
• Court-admissible testing to support potential legal needs, with additional documentation procedures
• Legal testing for surrogacy

Our comprehensive DNA test types include:

• Paternity 
• Maternity
• Court-Admissible
• Infidelity
• Immigration
• Adoption
• Forensic Services
• DNA Profiling
• Genetic Reconstruction

Relationship DNA testing is one of the most common reasons people reach out. These tests can help confirm biological relationships such as paternity, maternity, or other family connections like siblings or grandparents. Some people want testing for personal peace of mind, and others need results that may be appropriate for use in a legal process. We can describe the differences between tests that are set up for court-related documentation and those used for private information, so you can choose what aligns with your situation.

When you contact us about the DNA testing Rancho Cucamonga residents rely on, we will ask a few questions about who needs to be tested, whether anyone lives out of state, and if an attorney or government agency is involved. This helps us recommend the correct format, whether that is a court-focused test with strict identification procedures or a simpler option used only for your own records. Our goal is to match you with a test that fits your budget, timeline, and comfort level while still meeting any official requirements you may be working with.

If you are unsure which option you need, you are not alone. Many clients contact us with a general concern rather than a specific test name. We can talk through your goals, timing, and who will be involved, then recommend which tests clients commonly choose in similar situations.

Preparing for Your DNA Test

A small amount of preparation before your appointment can help the visit go smoothly and reduce the chance of delays. Taking a few minutes to gather documents and talk with anyone else who will be tested makes the process easier for everyone involved. When you schedule, we review these details with you so there are no surprises on the day of your visit.

Gather Any Required Documents

Most tests require government-issued identification for adults and appropriate documentation for minors, such as a birth certificate or guardianship papers. If another parent, relative, or legal representative needs to sign forms, it helps to coordinate with them before you come in. For families in Rancho Cucamonga working through active court or immigration cases, bringing any letters, case numbers, or written instructions you have received can help us align your DNA or genetic testing with those requirements.

What to Avoid on the Day of the Test

There are also simple, practical steps that can improve sample quality. For cheek swab collections, we generally suggest avoiding food, gum, or smoking for a short period before your appointment. If you take daily medications or have health conditions that might affect scheduling, you can mention this when we book your time so we plan accordingly. Thoughtful preparation on the front end often leads to a faster, more efficient visit and can help you get your results within your preferred timeframe.

What to Expect From Your Appointment

Schedule by Phone or Online

Knowing what will happen at your visit can take much of the uncertainty out of the process. When you call Fastest Labs of Rancho Cucamonga, we start by asking a few brief questions about the type of testing you need and who will be coming to the appointment. This helps us suggest appointment times and preparation steps that fit your schedule.

Easy Check-In Process

On the day of your visit, you arrive at our lab in Rancho Cucamonga and check in at the front desk. Our staff will review identification and, when appropriate, any paperwork needed for tests that may be used in legal settings. We explain each form before you sign, and answer questions before moving forward.

Private and Painless Sample Collection

Most DNA collection involves a simple cheek swab that is quick and does not require needles. For certain types of genetic testing, a blood sample may be appropriate, which is collected by trained staff using standard procedures. In either case, we work to keep the process as brief and comfortable as possible, and we are glad to answer questions, including those from children who may be present.

We understand that some clients feel nervous about any type of medical setting, so we explain how long the swab or draw will take, who will be in the room, and what you can do afterward. Parents often appreciate tips on how to prepare younger children, such as practicing opening their mouth wide for a cheek swab or talking through the visit the day before. Our collection rooms are arranged to offer privacy while still allowing a parent or guardian to be nearby when appropriate, which can make the experience easier for everyone.

Secure Sample Handling and Results

Once your sample is collected, it is labeled and processed according to our lab protocols. Typical turnaround time varies by test type and the number of individuals involved, and our team will give you an estimated time frame when you schedule. Many standard relationship tests are completed within a defined window (usually 2-3 business days). Results are then shared using a method discussed with you in advance, such as secure electronic access or another appropriate format.

For tests that may be used in legal matters, we follow a clear chain-of-custody process that documents who handled the sample from the moment it was collected until it reaches the testing laboratory. We maintain records in case an attorney, agency, or court in San Bernardino County later needs confirmation of how the sample was managed. When results are ready, we review the report format with you so you understand how to read the findings and what kinds of follow-up questions people commonly ask.

This structure is designed to keep your experience predictable and respectful from start to finish. If you have special scheduling needs, such as coordinating multiple family members, we encourage you to mention this when you call so we can help plan your visit.
