Our lab offers siblingship testing using state-of-the-art microarray technology. By testing hundreds of thousands of markers, we are capable of determining a wide range of human relationships. This includes siblings, grandparents, aunts/uncles, cousins, and infidelity testing. Your results will be reliable, strictly confidential and easy to understand. Recommended for determining familial relationships. *Please note that pricing may vary depending on your purchasing location due to factors such as foreign exchange rate, shipping and local taxes. Siblingship DNA Test If you've ever wondered if someone is your brother, sister, or half-sibling, a sibling DNA test will help you reach those answers. These DNA solutions help you determine if you share one or two biological parents with another person. What Is Sibling DNA Testing? Sibling DNA tests compare the likelihood that two people have the same biological mother or father. It is common for immigrant visas, questions of inheritance, and people who have had some new information come to light about their real parents. If you're considering a relationship with someone others think might be related to you, a sibling DNA test might give you some answers and peace of mind. Types of Sibling DNA Tests Our DNA tests show the probability of siblingship between two people. In a full- versus half-sibling test, the DNA of two people with the same biological mother is compared to determine how likely they have the same alleged father. We also recommend that the biological mother of the alleged siblings also provide a sample. This helps us determine which genes came from the mother and which were contributed by the father. Having the mother's sample gives a big boost to the conclusive results. We can also compare two people's DNA with different mothers to find out if they have the same father. We prefer to have the DNA of the mothers to deliver conclusive results. If there are undisputed siblings, their buccal swab samples will also help us conclude. How a DNA Sibling Test Works DNA sibling testing is simple! Each of the alleged siblings receives a sample collection kit. The included sterile swabs will be used to collect cells from the inside of your cheeks. After collecting your sample, follow the directions within the kit to return the kit back to our laboratory. Our turnaround time 3-4 weeks, after which you will receive your results in our secure, HIPAA-compliant online portal. Tips to Understand the Results of a Sibling DNA Test The report we provide explains the type of sibling relationship between you and the other tested individual or individuals. If our report shows less than 9%, there is not likely to be a sibling relationship. A result of 9% to 89% is inconclusive, and more biological relatives need to be tested. A result of 90% or higher indicates a high probability of a full-sibling or half-sibling relationship between the individuals. Read More
