SIBLINGSHIP DNA TESTS IN NEW YORK CITY
SIBLING DNA TESTS IN NYC:
CONNECTING WITH LOVED ONES
They say blood is thicker than water – family above all. That’s why many residents are heading to NYC DNA Testing Centers for DNA siblingship testing in New York City. DNA siblingship tests compare the genetic profile of one person to another to confirm or negate a genetic match. While it is preferable to test the parents to confirm a genetic likeness – the parents aren’t always capable or available to complete this testing. Hence, people seek DNA sibling tests in NYC to establish or deny sibling relationships.
HOW TO GET AN ACCURATE DNA SIBLING TEST IN NEW YORK CITY
Sampling the parents helps to establish a more detailed genetic profile. If you can identify the mother and she is available for testing, we advise including her in the Siblingship Test as well. Furthermore, including the mother in a Siblingship Test increases the probability of an accurate test significantly – by as much as fifteen percent.
UNDERSTANDING THE METRICS – THE DNA SIBLINGSHIP INDEX
DNA siblingship tests do not produce genetic profiles with identical genetic markers. Actually, the results of the test rely on statistical probabilities. To quantify the likeness of a sibling relationship between two alleged siblings, we use the ‘Siblingship Index’.
A calculated siblingship DNA index of less than 1.00 signifies that both of the alleged individuals have no biological relationship. An index exceeding a score of 1.00 acts as supporting evidence that the testees have a high probability of being biological siblings. A higher index score correlates with a greater chance of the two alleged individuals actually being related.

Full Siblings vs. Unrelated
This method of testing compares the genetic profile of two people with the same mother and compares their DNA with that of their mom. To complete this method of Siblingship Test, we recommend including the mother’s genetic profile into the test. Additionally, testing the same parent makes it possible to determine what characteristics acquired by the two test-takers stem from their father. As a result, this increases the conclusiveness of the test.
Full Siblings vs. Half Siblings
The DNA of both test-takers with different maternal origins are compared to determine the possibility of them being born from the same parent. Under these circumstances, we advise including samples from both of the biological mothers. By examining the mother’s genetic profiles, we are able to accurately find the traits inherited by these individuals from their father(s).
Twin Zygosity
Twin Zygosity tests investigate the genetic profile of 2 siblings against each other to determine whether or not they are identical or fraternal twins. Furthermore, this method of siblingship testing does not necessitate any other DNA samples for conclusive results.
