Full siblings, half siblings, or not siblings? Home DNA sibling test will verify the relationship between two or more individuals to assess if they are biologically related as siblings. Sibling tests can also be used to provide reliable parentage testing when one parent is deceased or unavailable. If you don’t need results for legal reasons like child support or custody, you can order an at-home DNA sibling test kit from EDC. We will ship the complete kit to you, then collect your DNA in the comfort of your own home with a simple cheek swab, and mail it directly to our CLIA-certified laboratory for processing.
