Genetic Reconstruction Testing in San Leandro

In-Person DNA Testing with Certified Collectors & Fast Appointments

When a direct DNA sample isn’t available, genetic reconstruction offers a reliable path to answers. We offer Genetic Reconstruction as part of our DNA testing services at Fastest Labs of San Leandro, helping families establish biological relationships by reconstructing the genetic makeup of a missing or deceased family member. Our certified collectors handle every collection in person, in a clean and comfortable facility, with wait times kept under five minutes.

Genetic reconstruction works by gathering DNA from close relatives of the person whose sample can’t be obtained. By analyzing shared DNA sequences among those relatives, a genetic profile can be constructed and compared against the child or individual in question. It’s most commonly used in paternity cases, but the same approach can help establish relationships between grandparents and grandchildren, siblings, and other biological relatives.

When Genetic Reconstruction Testing Is the Right Choice

There are several situations where collecting a direct sample simply isn’t possible. A potential father may be deceased, unreachable, or unwilling to participate. Someone may live too far away to come in for direct testing. In some cases, families prefer this approach because it lets the process move forward without requiring the involvement of the person in question, keeping things more confidential.

If any of these situations sounds familiar, genetic reconstruction may be the right fit. We’re here to walk you through your options.

How Genetic Reconstruction Testing Works

The process starts with a buccal swab collection, a simple cheek swab taken from each person providing a sample. Our certified collectors gather these samples from the relatives and other involved parties in our San Leandro lab, where every detail of chain of custody is carefully documented. The collection itself is straightforward and comfortable.

Genetic reconstruction typically requires DNA from at least two close biological relatives of the person being tested, such as a parent, sibling, or grandparent. The lab then analyzes those samples for shared, repeating DNA sequences to build a genetic profile, which is compared against the child’s DNA to assess the likelihood of a biological relationship. The more relatives who participate, the stronger the statistical confidence in the result.

Who Needs to Provide DNA Samples

The number of relatives required depends on whether the biological mother is participating. When the mother’s DNA is included, it can be excluded from the child’s profile, which isolates the paternal contribution and makes the comparison more precise. In that scenario, genetic reconstruction generally involves the child, the mother, and at least two close biological relatives of the father, such as his parent or sibling.

If the mother isn’t available or chooses not to participate, at least three close biological relatives of the father are typically needed to reach a reliable conclusion. Our team can review your specific situation and let you know which family members should come in.
