DNA Test - Greenwich, Connecticut

Greenwich CT DNA Testing Locations

Types of DNA Tests at our Greenwich, Connecticut clinics:

Paternity Testing can conclusively establish whether or not a man is the biological father of a child.

Relationship Testing for other close family relationships can be performed at our testing centers. Our DNA testing services can confirm or deny biological relationships between grandparents, grandchildren, siblings, half-siblings, aunts, uncles, nieces and nephews:

Grandparent DNA Test (if the father is not available for testing)
Sibling DNA Test (possible brothers, sisters, or half-siblings)
Avuncular DNA Test (aunt/uncle and niece/nephew)

Specimens we can test for DNA

The easiest and most reliable way to obtain a DNA sample for paternity testing is to swab the inner cheeks of the alleged father and child or children. These skin cells are known as buccal cells, and they rub off easily onto cotton swabs and remain in place for analysis by our laboratory.

Other specimen samples, such as hair follicles, fingernails, and garments that might contain someone's DNA, can also be tested. An Alternative Specimen DNA Test is done by ordering one of our testing kits online and shipping the specimens back to us.

Legal DNA Tests vs. "Peace of Mind" At-Home Tests

A Legal Paternity Test is a court admissible lab testing service performed at an AABB accredited laboratory. Accurate results for DNA paternity testing with 99.99% confidence or greater take about a week.

When deciding which type of DNA test is right for you, consider first what you might do with the results. A legal paternity DNA test will hold up in court for such matters as child support or to change the name on a birth certificate. This test must be performed using strict chain of custody procedures. Our Greenwich DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

Greenwich, Connecticut - DNA Testing

Establishing paternity in Greenwich, CT

Establishing paternity in Greenwich, Connecticut is an important step for parents, and there are two primary methods available to achieve this. The first option is voluntary, where parents can choose to sign the Acknowledgement of Paternity (AOP). This document can be signed at the birthing center or hospital in the presence of a notary public. It's crucial to bring a valid photo ID, and once signed, the AOP should be filed with the Department of Public Health. This process is free and faster than going through court proceedings. However, only choose this option when there are no doubts about paternity and both parents are confident about the biological father.

In cases where a voluntary agreement cannot be reached, parents can pursue establishing paternity through court. The judge may request a DNA test, which involves a simple and non-invasive cheek swab. These samples are sent to specialized laboratories for analysis, and the results are provided to the judge.

If you require accurate and reliable DNA testing services in Greenwich, Connecticut, Health Street is here to assist you. Whether it's for legal purposes or simply for peace of mind, we offer a range of testing options tailored to meet your specific needs.
