Frequently Asked Questions
-
A full siblingship DNA test compares DNA from two people to evaluate whether their genetic profiles are more consistent with a full-sibling relationship, a half-sibling relationship, or no tested sibling relationship.
It is an indirect relationship DNA test that can help when a direct paternity or maternity test is not available.
-
Two possible siblings are required. Each person provides a cheek-swab DNA sample.
If a common biological parent is available, that parent may also provide a cheek-swab sample. Including a parent can provide additional genetic information for the laboratory’s analysis.
-
A siblingship DNA test evaluates whether the DNA evidence is more consistent with full siblings, half siblings, or no tested sibling relationship. The strength and clarity of the analysis can depend on which relatives are available to test.
If a possible biological parent is available, a direct parent-child paternity or maternity test is typically more informative than an indirect sibling test.
-
No. This at-home relationship DNA test uses cheek-swab samples. A cheek swab collects DNA-containing cells from inside the mouth.
No blood draw, needle, doctor’s appointment, clinic visit, or laboratory visit is required.
-
If a common biological parent is available and willing to participate, including that parent’s DNA may provide additional genetic information for the laboratory’s relationship analysis.
The test can be performed using two possible siblings, but contact GameDay DNA before ordering if you need help choosing the appropriate testing configuration.
-
No. This is a self-collected, non-legal DNA test for personal knowledge only. It does not include the witnessed collection, identity verification, photographs, signatures, and documented chain of custody required for official use.
Do not use this kit for court, child support, custody, immigration, adoption, inheritance, birth-certificate changes, Social Security, or another official matter. If you need legally admissible results, arrange legal testing before samples are collected.
-
Results are typically available within 5 business days after the laboratory receives all required, acceptable samples.
The overall timeline also includes kit delivery, at-home collection, return shipping, laboratory intake, sample-quality review, and any recollection that may be necessary. Contact GameDay DNA to ask whether expedited service is currently available.
-
our confidential results are sent securely by email or made available through the online results portal after laboratory analysis is complete.
Use a private email address that you can access. Contact GameDay DNA if you need help accessing your report.
-
Yes. A parent or legal guardian can collect a minor child’s cheek-swab sample at home using the instructions included in the kit. The process is non-invasive.
Wash hands before collection, avoid touching the swab tip, and make sure every participant’s sample materials are labeled correctly.
-
The laboratory may request a new sample if a swab is insufficient, contaminated, damaged, incorrectly labeled, or otherwise unsuitable for testing. A recollection can extend the timeline for results.
Contact GameDay DNA before mailing a replacement sample to receive the correct instructions and learn about any applicable fees.
-
No. A self-collected at-home DNA test generally cannot be converted into a legal test after sample collection. Legal testing requires a qualified collector to verify identities, witness collection, and complete chain-of-custody paperwork at the time samples are obtained.
If you might need results for an official purpose, arrange a legal DNA test before collecting any samples.
-
Contact GameDay DNA before ordering if you are unsure whether you need a full siblingship test, half-siblingship test, paternity test, maternity test, grandparentage test, avuncular test, or legal DNA test.
Tell us which family members can participate and whether you need results for personal knowledge or an official purpose. Call 302-527-1789 or email info@gamedaydna.com.
