Discreet Testing to Determine Full or Half Sibling Relationships
When traditional DNA collection isn’t possible, our Forensic Sibling DNA Test offers a discreet, science-backed way to confirm whether two individuals share one or both biological parents. Whether you're working with personal items like hair, toothbrushes, or clothing, our forensic DNA testing helps reveal the truth, without needing a cheek swab.
What Is a Forensic Sibling DNA Test?
A Forensic Sibling DNA Test determines whether two people are full siblings (same mother and father) or half siblings (sharing only one biological parent) using non-standard DNA samples. This test is ideal when:
One or both individuals are unavailable for cheek swab collection
The testing needs to be done discreetly
Personal items (toothbrushes, razors, hair, etc.) are the only available sources of DNA
You need to determine parentage through a sibling connection
Our lab uses advanced forensic extraction techniques to isolate and compare DNA from personal items to determine sibling relationships with accuracy and confidentiality.
Common Use Cases
Discreet testing between siblings to check if they share the same biological father or mother.
Confirming family ties when a parent is deceased or missing.
Personal closure for questions about biological relationships.
Using items from childhood or shared spaces, like hairbrushes, toothbrushes, pillowcases, or hats.
Common types of forensic samples
