Our Sibling DNA Test will confirm if two or more people are full or half siblings. Results are provided in just 3 business days.
Due to New York State Department of Health regulations, we cannot offer any peace of mind paternity or relationship tests to New York residents.
From just $179, including your test kit and all lab fees, our Sibling DNA Test can help individuals determine whether they are full-siblings or half-siblings, with results in just 3 business days. When both people have the same biological parents, they are classed as full-siblings. Half-siblings are individuals who share only one biological parent, either the mother or father. When testing for sibling relationships, cheek swabs are used to collect DNA samples from each sibling. For the most conclusive result, we also ask for the biological mother's sample, if available. The DNA laboratory will then determine the genetic profile of the possible siblings and will calculate a sibling DNA index or likelihood ratio. A likelihood of greater than 10 indicates that the siblings are related, either full or half, but a likelihood of less than 0.1 does not support this. A likelihood that falls between 0.1 and 10 is inconclusive, which means that a relationship cannot be determined, based on the data collected and analyzed. The higher the value of the sibling DNA index, the greater the chance that the two individuals tested are full biological siblings. It is possible to analyze two individuals to determine whether they are more likely to share the same mother and father, share just one common parent, or be totally unrelated. You can order our Sibling DNA Test online now from just $179. The cost of the test includes your test kit and all lab fees. The test includes enough cheek swabs to test two siblings and the biological mother, if available. Your test kit will be sent out in discreet, plain packaging, for full confidentiality. If you would like to test three siblings, you can select this option for an additional $69 when placing your order. Our standard sibling test is already industry-leading, as it analyzes 25 DNA markers (the industry standard only analyzes 16-21 markers). What makes AlphaBiolabs unique is that we can also analyze up to 45 DNA markers. This allows more genetic material to be analyzed, which strengthens the result and provides additional reassurance. This is ideal for customers who want the most powerful DNA test available. It is also particularly useful in tests of a more complex nature, such as a sibling test, where the chance of obtaining a conclusive result will always be lower than the more straightforward paternity or maternity tests. This is because the DNA hasn’t been directly inherited. The enhanced test will increase the chance of obtaining a conclusive result. For $179, including your test kit and all lab fees, our Sibling DNA Test kit includes: If you need to test more individuals, you can easily select this option while placing your order. Once we have received your samples at our laboratory, we will email your password-protected results in 3 business days. Order your Sibling DNA Test online now for $179. Payment details are 100% secure and will never be sold to third party advertisers. Once you have received your kit, simply follow the instructions included to collect your samples. Rub the swab gently and painlessly on the inside of the cheek to collect cheek cells. Enough swabs are provided to test two siblings and the biological mother, if available for testing. If you would like to test three siblings, please select this option when placing your order, and additional swabs will be included in your kit (fees apply). For the most conclusive result, we do ask that the biological mother also provides a cheek swab sample, if possible. However, this is not essential, and we can still perform a sibling DNA test without the mother’s sample. Your test kit will contain enough cheek swabs to collect DNA from two siblings and the biological mother (if available). Simply buy your test online now, and we’ll mail it out to you immediately. Your test kit will be sent directly to your chosen address in discreet, plain packaging, for complete confidentiality. You can choose to receive your kit by USPS First Class Mail (included in the cost of your test), or upgrade to USPS Priority Mail (+$9.99) or USPS Priority Mail Express (+$24.99).
