Paternity Testing in Yonkers, New York

There are several types of DNA testing services that are offered at our Yonkers testing centers to validate close family relationships. The most commonly ordered DNA test is a legal paternity test to conclusively establish whether or not a man is the biological father of a child. Health Street’s 21 marker DNA paternity testing is the state of the art. Our paternity test results are statistically conclusive at the rate of 99.9% or greater.

Other DNA Tests

Relationship Tests to validate grandparent to grandchild, siblings, half-siblings, aunts, and uncles:

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)

DNA tests such as sibling or avuncular studies, can sometimes come back with a result of less than 95% certainty. This is normal, especially if only two parties participate in the test. Adding an additional close relative to the test helps us learn more about the family’s DNA composition and typically leads to a more conclusive result.

Specimens we can test for DNA

The easiest and most reliable way to perform a genetic sample collection for a paternity test is by a swab of the inner cheeks. These skin cells, known as buccal cells, rub off easily onto cotton swabs and remain in place, to be extracted by our testing laboratories for analysis.

Other specimens, such as hair follicles, fingernails, and garments that might contain someone’s DNA, can also undergo lab testing to see if there is a match. These non-standard DNA tests are done by registering online for an Alternative Specimen DNA Test (Nails, Teeth, Fabric). Once registered, you ship the DNA sample to our lab. We’ll attempt to extract the DNA and compare it to a cheek swab of the other party.

Legal DNA Tests vs. “Peace of Mind” At-Home Tests

When deciding which type of DNA test is right for you, consider first what you might do with the results. In order for the results to hold up in court, the DNA specimen must be collected at a clinic using strict chain of custody procedures. The DNA testing technicians at our Yonkers test centers are trained to follow guidelines that ensure that the results can be used for legal purposes.

The results of our legal DNA tests can be used for any legal purpose:

to change the name on a birth certificate
to petition for child support
to petition for survivor benefits
for child custody arrangements
to alter inheritance procedures or wills

Home tests offer more flexibility:

Home DNA tests are specimens containing DNA (or possible DNA) that are shipped to us for analysis. The results of these home tests cannot be used in court (since there is no way to prove whose specimens were actually sent). However, the tests are just as accurate and can provide peace of mind. At-home DNA tests also offer a lot more flexibility.

In addition to commonly mailed in DNA specimens like hair follicles, we can also extract DNA from other bodily fluids. We can even try and lift the DNA left on items like clothing, a toothbrush, or a straw. If we can get the DNA from the alternative item, we can then compare it to another person to see if they are related. Some examples include:

Stained garments
Mucus and other bodily fluids
Soda cans
Chewing gum

How to schedule a DNA Test in Yonkers NY

Scheduling a DNA test at one of our Yonkers clinics is simple and fast, and we often have appointments available in the same week, though it’s always helpful to schedule in advance to make sure you get the time you want. We have clinics in Yonkers, plus many more throughout New York and across the United States. During registration, we’ll show you the nearest locations so you can choose the one that’s most convenient. You’ll pick the times and days that you prefer.

You can set up separate appointments for each of the people being tested, either at the same location or at different locations. You’ll get an email and text message with your appointment information. There is no fee if you need to change the time or location of a DNA test appointment at any time.

How long it takes to get results of a DNA test

Paternity tests conducted at one of our Yonkers facilities typically take about a week to come back. Other relationship tests, such as sibling studies, can take a few days longer to come back. When the results are ready, you are notified immediately via email. Then, the hard copies of the paperwork are sent afterward via regular mail.

The DNA test appointment – what to expect and what to bring

The appointment itself only takes about 15 minutes. The specimen collection process is a simple and painless cheek swab. No needles are used. When you’re being tested at our Yonkers clinic, you’ll be asked to provide fingerprints and to show photo identification. We’ll also take pictures of the people being tested so that the final report will include legal assurances of who was actually tested.

For infants, hospital discharge papers qualify as identification. Otherwise, a birth certificate or social security card can be used as ID for a child. No other preparations are required for this appointment.

Does the mother need to be present at a paternity test?

If a man is considered the legal father of a child, then the mother does not have to be present or give consent for paternity testing. However, if he is not currently considered the legal father, then he cannot sign for the child. Therefore, the mother does need to be there. If neither parent is available, other legal guardians can bring the child so long as they have the right to make medical decisions on the child’s behalf.

DNA testing if one party is not in Yonkers

The two parties testing (for example: father and child) do not have to be tested at the same time or even at the same location. We have many clinics across New York as well as nationwide, so we can test one party in Yonkers and the other party anywhere else in the USA. The specimens are then matched up in the lab for analysis.

Laboratory certifications

Health Street works strictly with AABB Certified labs for DNA testing. All specimens that are collected in Yonkers or elsewhere are shipped securely from our testing locations to a nationally certified laboratory.

Facts about DNA Testing in Yonkers NY

Yonkers: New York City’s Sixth Borough

The city of Yonkers, New York, has always been known in relation to New York City. It’s located just two miles from the northernmost tip of Manhattan and is often called New York City’s ‘sixth borough.’ Within the last several years, the city has grown from a gritty industrial town to a dynamic and vibrant area with its own unique lifestyle. Luxury apartment buildings and condos have been constructed, and fine dining restaurants and entertainment venues have followed.

Public transportation makes it easier for people to commute into New York City, and younger professionals have snapped up new-built properties all over town. Yonkers is also a very diverse city, with more than 45% of residents speaking more than one language.

DNA, Adoption, and Paternity in Yonkers

One issue that has been receiving a lot of attention in Yonkers and the rest of Westchester County is adoptees’ rights. A recent bill passed in the New York State Senate in 2019 changed the law around adoption paperwork for adoptees over 18 years of age.

Previously, adoptees could only obtain a copy of their original birth certificate if they were under 18 years old. Now, this bill opens the door for older adoptees, going back to those born in 1930, to obtain their original birth certificate. According to the New York Office of Temporary and Disability Assistance (which administers child support), establishing a relationship between parents and children is key to the child’s well being.

Establishing Paternity for Married or Unmarried Parents in Yonkers

When a child is born and will be remaining in the custody of one or both parents, the parents must establish paternity. This is either done through a voluntary process called an Acknowledgement of Paternity, or by requesting DNA testing. However, it’s important to keep in mind that “although DNA testing can determine the identity of the biological father, it does not establish legal paternity.” Following the DNA test, the parents must proceed by establishing either a voluntary or court-ordered paternity relationship between the father and his child.

The legal paternity test is a key part of this process. According to local lawyer Elliot S. Schlissel, it’s important to keep in mind that not just any DNA test will be accepted. “There is a specific methodology and rules required before a DNA test can be accepted into evidence,” he says.
