SIBLING DNA TESTING
ANSWERS THAT HELP CLARIFY FAMILY CONNECTIONS.
Palmetto Compliance & Testing provides professional Sibling DNA Testing to help determine whether two or more individuals are biologically related as siblings.
Testing may be used to evaluate whether individuals are full siblings, half siblings, or biologically related through a shared parent. Testing is completed using a simple cheek swab and professional laboratory DNA analysis.
WHAT IS SIBLING DNA TESTING?
Sibling DNA Testing evaluates the biological relationship between two or more individuals to determine the likelihood that they share one or both biological parents.
Depending on the family relationship being evaluated, testing may help determine whether individuals are full siblings, half siblings, or unlikely to share the claimed biological relationship.
Common Uses
Sibling DNA Testing may be used for personal knowledge, family relationship verification, and other situations where information about a biological sibling relationship is needed. Testing for legal, government, or other official purposes may require additional identification, documentation, and chain-of-custody procedures.
SIMPLE & NON-INVASIVE COLLECTION
Collection is simple, non-invasive, and typically completed using cheek (buccal) swabs from each required participant. The collection takes only a few minutes, and specimens are properly prepared and submitted to the laboratory for analysis.
PROFESSIONAL LABORATORY ANALYSIS
Once collected, specimens are securely submitted to the laboratory for DNA analysis. The laboratory compares the participants' DNA profiles using established relationship-testing methods and evaluates the likelihood of the claimed sibling relationship.
FULL SIBLING VS. HALF SIBLING
Full Siblings
Share the same biological mother and biological father.
Half Siblings
Share one biological parent.
PARTICIPANTS MAY INCLUDE:
1. SIBLING 1
A DNA sample is collected from the first individual whose biological relationship is being evaluated.
2. SIBLING 2
A DNA sample is collected from the second individual whose biological relationship is being evaluated.
3. AVAILABLE BIOLOGICAL PARENT
When appropriate, including an available biological parent may strengthen the relationship analysis. Participant recommendations depend on the specific family relationship and laboratory requirements.
