Sibling Testing DNA

DNA Sibling Testing

Sibling DNA Test Can Establish Relationships

The sibling dna test can be used to establish whether two or more people share some of the same genes. This happens in cases where they have one or more parents in common. By measuring and analyzing the number of genes that are the same in two individuals, experts can determine the strength of the biological relationship.

This is done by DNA testing of both participants to determine whether the alleged brothers and sisters are related. By testing a parent’s DNA as well, the evidence is made even stronger. Negative results are often useful as well. If there is no genetic similarity between two individuals, the test proves the lack of biological relationship.

The test can also be used to determine parenthood (maternal or paternal) if a mother or father is not available. The strength of the sibling DNA linkage is expressed as a percentage. For instance, there can be a 98% statistical probability of a sibling relationship or an 83% probability, depending on the strength of the association.

Various Levels of Legal Validity in Sibling DNA Testing

The results from this type of test can produce peace of mind and settle ancient questions within the family or community. This type of test is often employed for genealogical charts.

However, this test does not prove a biological relationship for legal purposes. Because of the risk of confusion or contamination during the collection of sibling DNA samples, storage and shipment, and documentation, home-test kits are not considered legal proof of a genetic relationship.

If the sibling DNA test is conducted by a laboratory run by the American Association of Blood Banks (AABB), the test will produce court-admissible evidence of a biological relationship. These results can be used for child support or visitation rights; to legally change the name on a birth certificate; for immigration, inheritance or probate; or for immigration authorities such as the U.S. Citizenship and Immigration Services.

Process Stays the Same For At-home or Lab Test of Siblings

While the legal status of the tests vary depending on where and how they are conducted, all sibling DNA tests begin with a sample. It can be a cotton (buccal) swab that’s swiped against the inside of the cheek, or a small amount of blood, hair, skin or fingernail. While the validity of the at-home kit is determined by the care and accuracy of the person conducting it, legally approved labs must follow a strict protocol.

In these institutions, chain of-custody procedures require that the process be supervised and documented each step of the way.

If for any reason, you believe that the results of a sibling DNA test could be required in court or necessary for government approval of any sort, it’s best to request a court-admissible DNA test. The procedure for this type of sibling DNA test is very specific and we are set up to walk you through the entire process.

Terms & Conditions

By placing your order with All About Truth DNA Services, you agree to the following Terms and Conditions:

Although the information contained in this website is accurate and up to date, no representation or warranty, express or implied, is made to its accuracy or completeness.

Since in-home test DNA samples are being obtained without a strict chain of custody, the origin of such samples cannot be verified by either All About Truth DNA Services, it's employees, or the testing laboratory and therefore test results cannot be used in a court of law or for immigration purposes. This test is for personal use only.

In compliance with the New York State Department of Health regulations, we do not make in-home testing available to residents of New York. In this regard, All About Truth DNA Services disclaims any legal responsibility from its use of our online services to circumvent this regulation.

Test results are released only when all charges and payments made have cleared and have been paid in full.

Fees are non-refundable once we have shipped the DNA Home-self kit you purchased online.

Genetic mutations sometimes occur in ordinary, healthy people. These mutations surface in approximately 1-2% of paternity cases. When they do, the final test results depend on careful interpretation of the data by the laboratory scientists. If an inconsistency is detected, any guarantees on conclusiveness and turnaround time are void. Such inconsistencies often require extended testing which may affect probabilities of paternity and length of test duration.

Due to the complexity of genetic inheritance and despite extended testing procedures, some special tests (including Siblingship tests and genetic reconstruction) may reveal insufficient data to yield a definite exclusion or inclusion.

All About Truth DNA Services limits its liability to the cost of the test and disclaims liability for other losses, direct or indirect, arising from
the test results.

Once the report has been generated, we will not be able to alter it in any manner and therefore will not be able to correct any spelling of any names.
