Siblingship DNA Test

Service Description

The siblingship test evaluates whether two individuals share one or both biological parents, providing a probability of their sibling relationship. Results are AABB certified and typically delivered within two business days. In a full-sibling versus half-sibling test, the DNA of two individuals with the same biological mother is analyzed to determine the likelihood of sharing the same father. Including a sample from the biological mother is highly recommended, as it helps identify maternal genetic contributions, significantly enhancing result accuracy. For individuals with different mothers, we can compare their DNA to determine if they share the same father. Including samples from both mothers, if available, is preferred to ensure conclusive results. If undisputed siblings are available, their buccal swab samples can further strengthen the analysis. Pricing Includes testing for two alleged siblings, and testing for one mother (highly recommended). Additional fees apply for testing additional alleged siblings.
