When does turnaround time start?
Processing usually begins after the laboratory receives and accepts the sample, rather than on the date the order is placed.
Understand sample collection, expected turnaround times, test accuracy, privacy, legal requirements and report limitations before choosing a health-focused, relationship or pet DNA test.
These are the details most customers should understand before ordering. The exact instructions and processing time will depend on the selected test.

No. Depending on the analysis, a test may require a cheek swab, saliva, hair, stool, blood or another specified sample.
Many consumer tests provide screening, risk or trait information. They should not automatically be treated as a clinical diagnosis.
Frequently. Court, immigration or official relationship testing may require identity verification and a documented chain of custody.
Open a question below for practical guidance about test selection, collection, processing, privacy and legally documented DNA testing.
Begin with the question you want the test to answer. A genetic testing option may focus on inherited markers, traits or wellness-related information, while a pet DNA test may focus on breed, inherited disease markers or identity.
Review the sample type, report scope, intended use and processing time before ordering. A test designed for personal information may not meet legal or clinical requirements.
No. Many tests use a cheek swab or saliva sample, but certain analyses may require hair, blood, stool or another biological sample. Follow the instructions provided for the exact product you ordered.
Avoid eating, drinking, smoking or handling the collection device unless the test instructions specifically allow it.
The timeframe varies by analysis and normally begins after the laboratory receives an acceptable sample. Shipping time, sample quality, laboratory workload and repeat testing can affect delivery.
Use the estimated timeframe shown for the selected test rather than assuming every DNA analysis follows the same schedule.
Accuracy depends on the test method, markers analyzed, sample quality, reference data and the question the test is designed to answer. Laboratory accuracy is not the same as certainty about a future health outcome.
Read the report scope and limitations carefully instead of relying only on a general accuracy percentage.
Start with the report summary, then review the methodology, definitions and limitations. Separate confirmed findings from estimated risk, predisposition, trait or informational results.
The DNA results guide explains how to review common report sections without overstating what the findings mean.
No. A health-focused DNA test may provide useful screening or educational information, but it should not replace professional diagnosis, treatment or emergency medical care.
Discuss important or unexpected health-related results with a qualified healthcare professional who can consider your symptoms, medical history and other clinical information.
Before ordering, review how account information, samples and reports are stored, accessed and shared. Use a secure password and avoid sending sensitive reports through unsecured messaging channels.
Review the site's private and secure results information and applicable HIPAA notice for more detail.
An at-home test is commonly intended for personal information. A legally documented test may require supervised collection, verified identification, sealed samples and documented transfer between the collector and laboratory.
Review the legal chain-of-custody process before ordering a test for court, immigration or another official use.
Accreditation may matter when a relationship test is intended for a legal, court or immigration purpose. Requirements can vary by agency, jurisdiction and intended use.
Confirm the exact requirement before collection and review the information about AABB-accredited laboratories.
Pricing varies according to the sample type, number of markers, laboratory method, report depth, shipping and whether supervised legal collection is required.
Review the DNA test cost guide to understand what can influence the final price.
Avoid ordering a broad test and hoping it contains the answer you need. Start with the category that best matches the intended use.

A few minutes of review can prevent ordering the wrong analysis, submitting an unsuitable sample or misunderstanding the final report.
Decide whether the result is for personal information, professional discussion or an official legal purpose.
Confirm the sample type, collection restrictions and whether supervised collection is necessary.
Check when processing begins and whether shipping time is included in the estimated turnaround.
Review what the report includes, what it does not establish and whether additional interpretation may be needed.
