  • Laboratory Accreditations: AABB, CAP, CLIA, ISO17025

Reliable Core CODIS Markers

Our DNA sibling test focuses on the core loci recognized by CODIS, which are highly reliable markers in forensic DNA analysis. These markers meet stringent CODIS standards, ensuring accurate and trustworthy results.

Legal Sibling Test Option Available

If you need DNA sibling test results that are legally admissible, we offer a legal DNA test option. Our private sibling test is just as accurate as the legal test, with the only difference being the sample collection process. With the private test, you can discreetly collect the samples at home. In contrast, the legal test requires collection at a designated site in the presence of a third-party witness. Both tests provide the same reliable results, with the only distinction being whether the collection is witnessed or done privately. Schedule a legal DNA sibling test by clicking here.

If the test participants live in different locations, we offer the option to split the DNA test kit and send the components to different addresses. Simply provide the mailing addresses and names of the test participants under the Additional Information section during checkout. Please note that an additional shipping fee of $10 will apply for each additional address within the United States. Our laboratory will process the samples upon arrival, and each kit component is individually barcoded for accurate tracking.

It’s important to note that DNA sibling tests are not as powerful as DNA paternity testing. While our DNA paternity test provides an absolutely conclusive result regarding paternity, a DNA sibling test offers a statistical analysis of the probability of a sibling relationship. If testing the alleged father using a DNA paternity test is possible, it is recommended as the most conclusive and powerful test. However, in situations where testing the alleged father is not possible, a DNA sibling test can provide valuable insights into the statistical likelihood of a full or half-sibling relationship.

The sibling test results are determined through a statistical analysis based on the expected genetic similarities observed in true full and half sibling pairs. During the analysis, the autosomal STR profiles of the alleged siblings are to generate a Combined Kinship Index value. This value represents the probability of a sibling relationship, taking into account the statistical expectations for genetic matches among siblings.

Here is a general interpretation of the Combined Kinship Index values:

  • Combined Kinship Index >10000 = Practically proven
  • Combined Kinship Index from >1000 to 10000 = Highly likely
  • Combined Kinship Index from >100 to 1000 = Very likely
  • Combined Kinship Index from >10 to 100 = Likely
  • Combined Kinship Index from >1 to 10 = Slightly more likely than unlikely
  • Combined Kinship Index of 1 = Inconclusive
  • Combined Kinship Index from 0.1 to <1 = Slightly more unlikely than likely
  • Combined Kinship Index from 0.01 to <0.1 = Unlikely
  • Combined Kinship Index <0.01 = Highly unlikely

No, the home sibling test is for personal knowledge only. It is not suitable for legal purposes that require strict adherence to the chain of custody. If you need test results that can be used as legal evidence, we highly recommend choosing the legal DNA test. The legal DNA test ensures that samples are properly documented, handled, and stored to maintain their integrity and admissibility in a court of law. Sample collection for the legal test must take place at a designated location with an impartial third-party witness present. Click here to schedule a legal sibling DNA test.

The DNA sibling test is not as powerful as the DNA paternity test. The power of the DNA sibling test can be increased by adding the mother to the test or by adding more siblings.

In cases where the alleged father cannot be tested and the question is whether 2 siblings who share the same mother also share the same father, a DNA sibling test can provide the likelihood that sibling pairs are full siblings (same mother and father) or half siblings (only one parent in common).

The DNA sibling test compares the STR profile of siblings to generate a full sibling index and a half sibling index. Theses indexes provide the likelihood that two individuals are full or half siblings. It will also provide the likelihood that they are not related at all.

The DNA sibling test kit does not have an expiration date, so you can purchase it in advance and take it at any time. After the samples are collected, the DNA is good for at least 3 months at room temperature so you have lots of time in the event that you cannot send it back right away for testing. Just remember to follow the instructions in the kit to ensure that you collect the samples correctly.
