What Is Siblingship Testing?

Siblingship testing is used when the sample for the alleged father or mother cannot be obtained. The testing is performed between alleged siblings to determine biological relationship. There are two siblingship tests: full vs half and half vs unrelated. Testing can be performed between the siblings only, although we recommend providing a mother's sample with the siblings to improve the statistics and limit the chance of obtaining inconclusive results.

Full v. Half - The siblings being compared share the same mother but are unsure of the father.

Half v. Unrelated - The siblings being compared know they have different mothers but believe they might share the same father.

Conclusive & Inconclusive Results

Unlike Paternity testing, siblingship testing is a second degree relationship and could require additional samples to obtain a conclusive result. The mother of the child is STRONGLY recommended for all relationship tests to improve the statistics and limit the possibility of additional testing.

Conclusive - Results that fall in the ranges of 0.00-9.99% or 90-99.99% provide enough statistical evidence to confidently report the results as excluded or cannot be excluded.

Inconclusive - Results that fall 10-89.99% do not provide enough statistical evidence to confidently report the results as excluded or cannot be excluded. At this time your results will recommend providing additional participants. This will help drive the results towards conclusive results.

Informational Siblingship

An Informational test is for your peace of mind and is not court admissible. You may choose to perform the collection in the comfort of your own home or schedule an appointment with one of our certified collectors. No identification is required and results are ready within 1 business day of receipt of all participants' samples.

If you are unable to swab one of the participants you may submit a contact article. A contact article is anything the participant came into contact with other than a buccal swab. There is no guarantee a profile will be obtained from a contact article. We are unable to determine if a profile is obtainable until all lab processes have been completed; therefore a refund will NOT be issued if the contact article does not produce a comparable profile. Cases that include contact articles have an extended turnaround time of 5 business days, as well as additional fees, please contact DNA Solutions to order your kit if you plan on using contact articles.

To ensure your privacy all kits are shipped in discreet FedEx packaging addressed from Fulfillment Department.
