Understanding Sibling DNA Testing
What Is a Sibling DNA Test?
A sibling DNA test estimates the likelihood that two or more people share one or both biological parents. Common uses include confirming full-sibling or half-sibling relationships, indirectly establishing paternity, or providing evidence in legal cases such as immigration, custody, or inheritance disputes.
How Does Sibling DNA Testing Work?
Cheek swab samples from siblings are collected
Samples are analyzed in an AABB-accredited lab using advanced DNA techniques
Results are ready in about 5 business days
Types of Sibling DNA Tests Available
Full Siblingship with a Common Parent
Both siblings share the same mother; want to know if they share the same father (father not available)
Including the mother’s sample boosts accuracy
Full Siblingship without a Common Parent
Mother unavailable; test can still be done, but including her sample is recommended for conclusive results
Half Siblingship (Different Mothers, Same Father)
Both mothers participate for maximum accuracy
Useful when siblings know they have different mothers but want to confirm a shared father
Half Siblingship without Parent Samples
Test can proceed if no parent samples are available
At least one parent sample is recommended for stronger results
Legal and At-Home Sibling DNA Testing Options
Legal Sibling DNA Testing
Legal DNA tests maintain strict chain-of-custody protocols, making them court-admissible and ideal for:
Inheritance claims
Adoption processes
GameDay DNA ensures every legal test meets all court and government requirements.
At-Home DNA Testing
At-home Kits are ideal for personal peace of mind. They are just as accurate as legal tests but are not valid for court purposes. Results are confidential and delivered quickly.
Sibling DNA Test Costs in Illinois
At-Home Tests: Start at $300

Expedited Results: Additional fee available
Flexible payment plans make testing accessible for all.
Establishing Paternity With Sibling Testing in Illinois
In Illinois, individuals seeking to establish paternity have access to various resources. The Illinois Department of Healthcare and Family Services (HFS) offers assistance with paternity establishment, including information on filing a Voluntary Acknowledgment of Paternity (VAP) form at hospitals and birthing centers. Legal aid organizations and family law attorneys can provide guidance and representation in paternity cases, especially when court involvement is necessary for child support or custody matters. Additionally, the Illinois Child Support Services (CSS) program helps in locating absent parents, establishing paternity, and ensuring child support payments are made. These resources aim to protect the rights and well-being of children by establishing legal fatherhood and securing the financial support they deserve.
Limitations, Risks, and Key Considerations for Sibling DNA Testing
While sibling DNA testing delivers up to 99% reliability, it’s important to understand its limitations and potential risks:
Accuracy Variations: Results may vary depending on whether full-siblingship or half-siblingship is being tested.
Sample Quality: Poor-quality DNA samples can impact test accuracy.
Mother’s Sample: Including the mother’s DNA sample increases reliability, but it’s not always required.
GameDay DNA’s experts guide each client through these considerations for the absolute best outcome.
Frequently Asked Questions About Sibling DNA Tests in Illinois
What Makes a Legal Sibling Test Necessary?
Legal sibling DNA tests are required when results must be admissible in court for cases such as child custody, inheritance, or immigration. Illinois law requires strict chain-of-custody protocols and lab accreditation for all legal testing (Illinois Parentage Act of 2015, 750 ILCS 46/614; IL Supreme Court Rule 417).
Can I Collect Samples at Home for a Legal Test?
No. Legal DNA tests in Illinois must be collected by an authorized professional to maintain chain-of-custody for court validity. At-home kits are available for personal information only, not admissible in court (HFS: Paternity Info; IL Parentage Act 2015).
Are At-Home DNA Tests as Accurate as Legal Tests?
Yes! Both use accredited laboratories for up to 99% accuracy; however, only legal tests with strict chain-of-custody are admissible in Illinois courts (HFS: Paternity FAQs; SSA Guidance for IL DNA Evidence).
How Long Does It Take to Get Results From a Sibling DNA Test?
Results are generally available within 5 business days after the lab receives samples (HFS: Paternity Information).
Can Sibling Testing Be Used to Prove Half-Siblingship?
Yes! Sibling DNA tests can prove whether two people share one biological parent (half-siblings) or both (full-siblings), and Illinois courts accept these results if legal protocols are met (IL Parentage Act of 2015; HFS: Paternity Info).
Is Sibling DNA Testing Admissible in Court in Illinois?
Yes! Legal sibling tests performed with chain-of-custody by an accredited lab are court-admissible for custody, inheritance, and immigration (750 ILCS 46/614; IL Supreme Court Rule 417).
How Much Does a Legal Sibling Test Cost in Illinois?
Legal sibling DNA tests typically cost $400–$599 depending on expedited or mobile services. HFS or the child support program may provide testing at reduced cost in some cases (HFS Paternity Info; Parentage Act Guidelines).
Can I Use Sibling Testing for Immigration Cases?
Yes! Immigration cases often require sibling DNA testing if parentage is not possible. Legal results must meet AABB-accredited lab and USCIS requirements.
