DNA Predicts Response to Weight-Loss Drugs

| May 23, 2026

For some time, genetic scientists have shown that DNA determines certain health markers that make someone more susceptible to obesity than others. Using these health markers, dieticians claim to craft diets tailored for individuals looking to lose weight through diet. While these diets work for some, they don’t for others; using a genetic test to help individuals lose weight has generally gone out of style

Now, scientists claim there is a new way genetics can assist obese persons: by anticipating their response to weight loss drugs like GLP-1. The test calculated a person’s CTS–calories to satiation, essentially, how many calories it takes for someone to feel full. The test revealed the following results:

  • “People with a high satiation threshold lost more weight on phentermine-topiramate. This drug may help control portion size and reduce large-meal overeating (hungry brain).
  • People with a low satiation threshold responded better to liraglutide. This drug may reduce overall hunger and frequency of eating (hungry gut).”

The scientists were very pleased with the results, stating that it would benefit those with obesity and their journey to become healthier. It also makes treatment plans more cost-effective for obese persons, since they know which drug will help them lose weight.

While science continues to advance with genetic testing, the primary and most accurate use for genetic testing is paternity. Paternity testing from DNA Paternity Testing Centers is 99.99% accurate and is admissible in court for paternity rulings.

DNA Tests Helps Families Reunite After Disasters

| May 11, 2026

Natural or unplanned disasters are a huge risk to a child’s well-being. When a catastrophe strikes, families can be suddenly separated, with no preparation for the care of the children or plans for reunification.

Children are particularly vulnerable during disasters; they may not know how to protect, feed, or care for themselves until they can be reunified with their families. This can lead to greater fatalities.

Another challenge of reunification after a disaster is for preverbal or nonverbal children. Young or nonverbal children, unable to even say their name, can go unidentified for extended periods of time while family members search desperately for them.

However, DNA testing can help disaster relief operations reunite families after a catastrophe. Preverbal and nonverbal children, unconscious, or deceased children, can be reunited with their families quickly using a simple DNA test.

While there aren’t many natural disasters or catastrophes in America, DNA testing is a necessity for other countries more prone to disasters. Additionally, Chung and Blake point out, “With disasters expected to increase in frequency and severity due to global climate change, population growth, worsening pollution, and political instability, more children are expected to become separated from their families as a result of disasters. Whether a disaster occurs by a force of nature or as a man-made result of human intent, preparation for family separations and prioritization of prompt, accessible, and safe tools to facilitate family reunifications are necessary.” It’s possible that DNA testing may need to be used for local reunification in the near future.

What Genetic Testing Doesn’t Tell You

| April 29, 2026

There are countless genetic tests available that reveal various results. Paternity, ancestry, diet recommendations, disease markers, and so much more information are ready to be revealed after spitting in a tube.

For years, these types of tests have been hyped by fans or recommended by physicians. But now that the publicity has settled down, is there something genetic tests don’t tell us?

Are Genetics Supreme?

As it turns out, scientists are discovering that genetics isn’t as important to overall health as once thought.

“We’re learning that genes don’t matter as much as people thought,” says Patrick Turley, associate professor (research) of economics. “We used to believe there might be individual genes that have major effects on diabetes, or even IQ. What we know now is very different: Traits are shaped by all our genes working in concert. Millions of genetic markers nudge us in subtle ways, shaping probabilities rather than certainties.”

Although some conditions can be traced to one specific gene, most diseases are a combination of genes and factors. This makes it almost impossible to predict an individual’s risk.

Additionally, having risk factors doesn’t guarantee an individual will get the disease. Those who receive higher than average results may feel their destiny is set in stone. But this simply isn’t the case.

Genetics Are Best For Paternity

While some genetic testing can give inconclusive information, the accuracy for paternity testing is nearly 99%. DNA testing is the most accurate way to determine paternity.

What’s the Difference Between Cheek Swab and Blood Paternity Tests?

| April 15, 2026

DNA tests can be used for many things: paternity, ancestry, genetic markers, weight loss strategies, and more. But when you’re looking for answers to your paternity questions, you want conclusive results. While it might be harmless to have mistakes regarding ancestry, you don’t want any speculation about paternity!

There are two main ways of acquiring paternity results: a cheek swab and a blood draw. Is one more accurate than the other? Which is the preferred method?

Cheek Swab Genetic Testing

DNA can be obtained with a cheek swab. This is a non-invasive test where the inside of both cheeks is swabbed with a cotton swab to obtain genetic material. The swab is placed in a test tube and shipped to a testing facility. The results for a cheek swab are 99.9% effective when tested by an AABB or ISO-certified company.

A cheek swab test is ideal for young children and infants because it is painless, quick, and non-invasive.

Blood Sample Genetic Testing

Blood samples are generally considered the gold standard for genetic testing, especially for court cases. This is because blood samples give a higher concentration of DNA and are therefore thought to be more reliable. However, blood samples can be harder to maintain because they involve a needle. It is harder to obtain blood from children and infants and is more painful.

Which Is Better: Cheek Swab or Blood Sample?

Although blood samples give a higher concentration of DNA, cheek swab testing is highly accurate and acceptable in court when tested by an AABB or ISO-certified company. Cheek swab tests are preferred for young children and infants because it is quick and painless. It can even be done at home! DNA Paternity Testing Centers offers several paternity testing packages that are admissable in court. Shop our testing options today!

How Does My Child Take a DNA Test?

| March 21, 2026

If you are contesting your child’s paternity in court, then your child will need to take a DNA test. To be court-admissible, the DNA test must be collected by a neutral third-party company. Additionally, the laboratory must be an AABB-accredited facility. These requirements help you accurately prove your child’s paternity without bribery or falsification.

How does your child take a DNA test? While it might seem complicated, it’s actually very simple. Your child will take the DNA test the same way the parents do! Testing is painless and quick. Swab the inside of your child’s cheek, drop it into the test tube, and submit the test tube for analysis. That’s it!

In some cases, you may want to prove your child’s paternity before he or she is born. You can prove this in three ways:

  • Cervical Villis Sample (CVS): which can be collected at 10 to 12 weeks of pregnancy.
  • Amniotic Fluid: The preferred method, which can be collected at 12 to 21 weeks of pregnancy.
  • Non-Invasive Blood Sample: This can be collected any time after 12 weeks of pregnancy. DNA Paternity Testing Centers offers this blood sample kit on our “Specialty Testing” page.

DNA Paternity Testing Centers offers any paternity testing kits you may need. We offer standard, expedited, and home test kits that give you accurate results in three to five days. All three kits can be used for personal or legal use. We also offer a non-invasive blood sample kit, which gives you results in seven to ten business days.

No matter your need for proving paternity, DNA Paternity Testing Centers is the most convenient and accurate testing center available!

With over 2,000 centers nationwide, DNA Paternity Testing Centers is one of the largest, most affordable networks of accredited DNA testing labs in the United States. Our price is unbeatable without sacrificing quality. We offer DNA testing for paternity, maternity, and all other relationships, such as grandparents, siblings, aunts, and uncles.

Can I Use Any DNA Test Company for Court Admissible Testing?

| March 7, 2026

Contesting the paternity of your child can be a challenging and emotional time. Mother, father, and child have the legal right to know the child’s paternity. In many cases, the mother and potential father(s) may be asked to present DNA testing in court to confirm or deny the child’s paternity to settle custody cases.

DNA testing is not always cheap, and for this reason, it’s understandable to shop for the cheapest option. Or, you may want to “get the most bang for your buck” by using a more advanced DNA test, like a test that gives your genetic predispositions for certain diseases.

Not all DNA tests are the same. Your genetic code contains millions of data points, and certain DNA tests only pull out specific information. The judge doesn’t need to know your genetic disease predispositions to confirm your paternity of a child. In this case, you only need to confirm or deny paternity.

Additionally, only certain DNA tests can be admissible in court. For a DNA test to be court-admissible, it must be performed by a neutral third party. A form of identification is required at this collection, such as a photo ID, passport, birth certificate, social security card, etc. Also, a photo is taken of all parties participating in the DNA test.

The laboratory performing the DNA test must be an AABB-accredited facility. This is not the case for many DNA testing kits. However, all of the DNA Paternity Testing Center testing is performed by accredited laboratories. Our kits can be used as court-admissible tests.

With over 2,000 centers nationwide, DNA Paternity Testing Centers is one of the largest, most affordable networks of accredited DNA testing labs in the United States.

DNA Paternity Test Accuracy

| January 30, 2026

Accuracy is one of the most important concerns people have when considering DNA paternity testing. Fortunately, modern DNA testing is supported by decades of genetic research and strict laboratory standards.

Understanding what protects accuracy and what can compromise it helps build confidence in the results.

Why DNA Testing Is Highly Reliable

DNA contains specific genetic markers that are inherited from biological parents. By comparing these markers between a child and an alleged father, laboratories can determine whether a biological relationship exists.

According to MedlinePlus, DNA testing is one of the most reliable methods for determining biological relationships.

What Ensures Accuracy

Several factors protect the accuracy of DNA paternity testing:

  • Proper sample collection
  • Secure handling and labeling
  • Accredited laboratory analysis
  • Multiple quality control checks

The National Human Genome Research Institute explains that standardized laboratory procedures are essential for reliable genetic testing.

Why Professional Collection Matters

Errors are rare, but when they occur, they are often linked to improper collection or handling. Professional collection helps prevent:

  • Sample contamination
  • Mislabeling
  • Chain-of-custody errors (for legal tests)

This is especially important when results must meet legal or immigration requirements.

Understanding Probability Statements

Paternity test results are typically expressed as a probability of relatedness. High probabilities reflect strong genetic evidence, while exclusions clearly indicate no biological relationship.  Accredited labs use conservative statistical models to ensure results are scientifically sound.

When Results Are Unexpected

Receiving unexpected results can be emotionally challenging. It’s normal to need clarification or time to process the information. Reputable testing providers are prepared to explain results clearly and answer follow-up questions.

Confidence Through Process

Accuracy is not just about science, it’s about process. Working with a provider that follows accredited standards from collection through reporting helps ensure confidence in the final results.

DNA Paternity Testing Centers follows established standards to protect accuracy and integrity at every stage of testing.

Legal vs Non-Legal Paternity Testing

| January 17, 2026

One of the most common points of confusion for individuals considering DNA paternity testing is whether they need a legal or non-legal test. While both rely on the same scientific DNA analysis, they serve very different purposes and are handled in different ways.

Understanding this distinction early can help prevent delays, rejected results, or the need to repeat testing.

What Is Non-Legal (Informational) DNA Paternity Testing?

Non-legal paternity testing is typically used for personal knowledge. The samples are usually collected without identity verification or formal documentation, meaning the results are not admissible in court.

This type of testing may be appropriate for:

  • Personal reassurance
  • Family understanding
  • Medical or genealogical knowledge
  • Private decision-making

The science behind the test is still accurate, but the results are intended for informational use only.

What Is Legal DNA Paternity Testing?

Legal DNA paternity testing follows strict chain-of-custody procedures so results can be used for official purposes. This includes:

  • Verified photo identification
  • Witnessed sample collection
  • Secure handling and documentation
  • Direct reporting of results

Legal DNA paternity testing follows these strict procedures to ensure that results are accurate, secure, and admissible for official purposes such as court cases, child support, custody matters, or immigration. According to the American Association of Blood Banks (AABB), these safeguards are essential for maintaining the integrity of legally admissible DNA test results. Chain-of-custody protocols prevent tampering, contamination, or misidentification, giving courts and agencies confidence that the results are reliable, defensible, and scientifically valid.

When Legal Testing Is Required

Legal paternity testing is commonly required for:

  • Family court cases
  • Child support or custody matters
  • Birth certificate changes
  • Immigration applications
  • Government or agency requests

For example, the U.S. Citizenship and Immigration Services (USCIS) requires DNA testing to be conducted by AABB-accredited laboratories when used for immigration purposes.  This requirement exists to protect everyone involved and to ensure the results can be trusted. This way, immigration decisions are based on reliable evidence that meets federal requirements, giving families confidence that their application will not be delayed or denied due to improper testing procedures.

Accuracy Is Not the Difference

It’s important to note that accuracy is not what separates legal from non-legal testing. Both tests analyze the same DNA markers. The difference lies in documentation, verification, and compliance.

How to Choose the Right Test

Choosing the correct test depends entirely on how the results will be used. If there is any possibility that results may need to be submitted to a court or government agency, legal testing is typically the safer option.  Speaking with a qualified testing provider before scheduling can help ensure the correct path is chosen from the start.

If you’re unsure which type of DNA paternity test applies to your situation, DNA Paternity Testing Centers can help guide you before testing begins.
