Understanding Your DNA Test Results

You’ve gotten the test, now how can you go about understanding your DNA test results? DNA testing has become an increasingly popular tool for gaining insights into ancestry, health, and identity. Whether you’ve taken a DNA test for personal curiosity, medical reasons, or legal purposes, understanding the results can sometimes be challenging. In this blog, we’ll guide you through the key aspects of DNA test results to help you make sense of the information you receive.

Understanding Your DNA Test Results

Understanding Your DNA Test Results

The Basics of DNA Testing

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. DNA testing analyzes specific regions of your DNA to provide information about your genetic makeup. The most common types of DNA tests include:

Ancestry DNA Tests

These tests explore your genetic roots by comparing your DNA to a database of genetic information from various populations worldwide. They can provide insights into your ethnic background and ancestral origins.

Health DNA Tests

Health-related DNA tests examine your genetic predisposition to certain health conditions and traits. They can provide information about potential risks for diseases, carrier status for genetic conditions, and personalized health recommendations.

Relationship DNA Tests

Relationship tests, such as paternity, maternity, and sibling tests, are used to establish biological relationships between individuals. These tests are often used for legal, personal, or immigration purposes.

Interpreting Your DNA Test Results

Once you receive your DNA test results, it’s important to understand the different sections and what they mean. Here are some key components you might find in your report:

Ancestry Composition

An ancestry composition report breaks down your genetic heritage by percentage, showing which regions or populations your DNA matches. This section often includes a map highlighting your ancestral origins and a timeline of your genetic history.

Health Risk Reports

Health DNA tests provide reports on your genetic risk for various conditions. These reports usually categorize risks as higher, average, or lower based on your genetic markers. It’s important to remember that these reports are not diagnostic but indicate potential risks that can be influenced by lifestyle and environmental factors.

Carrier Status

Carrier status reports indicate whether you carry genetic variants associated with certain inherited conditions. Being a carrier means you may not show symptoms but could pass the variant to your children.


Trait reports offer insights into genetic traits such as eye color, hair type, and taste preferences. While these traits are influenced by multiple factors, DNA testing can provide an interesting look at how genetics contribute to your physical characteristics and behaviors.

Understanding Genetic Terminology

DNA test results often include specific genetic terminology that can be confusing. Here are some common terms you might encounter:


An allele is a variant form of a gene. Each individual inherits two alleles for each gene, one from each parent. Alleles can be dominant or recessive, influencing traits and conditions.


Your genotype refers to the specific genetic makeup at a particular location in your DNA. It’s represented by the combination of alleles you inherit from your parents.


Phenotype is the observable physical or biochemical characteristics of an individual, determined by both genetic makeup and environmental factors.


A mutation is a change in the DNA sequence. Some mutations can lead to genetic disorders, while others may have no effect or be beneficial.

Next Steps After Receiving Your Results

Receiving your DNA test results is just the beginning. Here are some steps you can take to make the most of your genetic information:

Consult a Genetic Counselor

If your results indicate a higher risk for certain health conditions or if you have questions about your genetic information, consider consulting a genetic counselor. They can provide personalized insights and guidance based on your results.

Follow Up with Healthcare Providers

Share your health-related DNA test results with your healthcare provider. They can help you understand the implications for your health and develop a plan for monitoring or mitigating risks.

Explore Your Ancestry

Use your ancestry DNA results to connect with distant relatives, build your family tree, and learn more about your heritage. Many DNA testing companies offer online platforms for exploring genetic matches and ancestry records.

Stay Informed

Genetic research is continually evolving. Stay informed about new discoveries and updates related to DNA testing by following reputable sources and considering additional tests as needed.

Understanding Your DNA Test Results: Conclusion

Understanding your DNA test results can provide valuable insights into your ancestry, health, and relationships. By familiarizing yourself with the key components of your report and the genetic terminology used, you can make informed decisions about your health and heritage.

How Does A DNA Test Work?

How does a DNA test work? Have you ever been in doubt of your family bloodline or questioned about you being part of a specific family? Well, DNA tests help you remove those doubts and uncertainties. DNA tests involve testing your DNA profiles to know if a specific person shares biological traits with someone else. There are many testing methods and types of DNA tests that help you get an accurate result.

Most DNA testing involves using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). This is one of the most advanced methods of testing in history that gives you accurate results of your DNA. More importantly, there is no harm in going for one. To learn more about DNA tests and how they work, read further below.

How Does A DNA Test Work?

What is a DNA Test?

The purpose of a DNA test is to find the roots of different diseases and changes present in your DNA. These tests are essential to keeping people safe from further risk. DNA is a code present in our bodies that makes up genes. These genes instruct our bodies to function in their unique ways. These tests can point out any possible disease that you’re most likely to fall victim to. They also help confirm your biological relationship with someone like your parents, siblings, grandparents, etc.

DNA Testing Procedure

The DNA testing procedure consists of four main steps that help you achieve accurate results. Mentioned below are the four main steps that make up the DNA test:

1.     Extraction

The extraction step involves breaking open the nucleus that houses the DNA. So when you break open the nucleus of cells, the DNA molecules release into the solution. The technicians may also separate DNA molecules from other cellular materials and debris that are usually present in biological samples.

It is impotent to remove these materials as there can be a potential inhibitor on the other DNA testing step. Therefore, isolation of the DNA molecules is very important.  There are two distinct extraction methods. These include Organic Extraction and a robotic extraction system known as the Maxwell.

2.     Quantitation

During the Quantitation process, technicians will assess and measure your DNA samples to ensure the right quality and quantity. DNA testing laboratory standards must make sure that the extracted DNA is only from a human. They will also note the amount of DNA you provide, as this is very important for the other steps to take place. The amplification system needs a narrow range of DNA input, so they will have to measure the samples taken from you.

The Quantitation step goes through the Quantifier DNA Human Quantification Kit through BCA. From there, it runs on all the samples using an instrument known as the ABI PRISM 7500 Sequence Detection System. This step takes around 5 hours, in which set-up takes around 60 minutes, and the instrument’s running takes two hours.

How Do DNA Tests Work?

3.     Amplification

The PCR technique is one of the main traits of the DNA Amplification process. It essentially allows technicians to produce millions of DNA copies of a specific sequence. The Polymerase Chain Reaction (PCR) takes only a few hours; hence it is very efficient. The purpose of this step is to get the right quality and quantity, especially for forensic DNA samples from a crime scene. The process of heating and cooling the samples in a thermal cycling pattern for over 29 cycles ensures quantity and quality.

4.     Capillary Electrophoresis (CE)

The last step involves the separation of amplified DNA molecules within large mixtures. This last step helps distinguish all the molecules from one another. To achieve this, you need to carry out the Capillary Electrophoresis step. It starts off by processing an electric current through the DNA molecule sample. Thanks to the electrical current, these molecules can enter a thin capillary consisting of gel-oriented polymer. Finally, that helps them migrate to the positive anode, which is at the end of the capillary.

Most DNA molecules consist of a negative charge; hence this step is essential. The technicians separate the PCR products by size. Smaller DNA molecules usually have an easier time entering the polymer compared to larger ones. Finally, the technicians collect all the data and gather it on a computer attached to a CE instrument. With the help of authentic software, they achieve a developed DNA profile. There are different instruments for this step that helps analyze DNA samples effectively, taking altogether around 60 minutes.

The Takeaway: Consult AB DNA Testing for All DNA Testing Services

If you want to find out about your family tree, ethnicity, health conditions, etc., a DNA test is what you need. DNA tests do a lot more than just confirm something, as they also warn you about possible health issues. To achieve authentic DNA results, get in touch with AB DNA Testing Services.

Parental DNA Testing Process

How does the parental DNA testing process work? The most important and popular use of DNA testing is the confirmation of the child’s biological parents. The confirmation of the child’s biological parents is crucial for clearing away doubts regarding the child’s birth. It is also very decisive for children’s rights and custody during conflicts or divorce between the parents.

Although other biological identification tests were in use before the advent of DNA testing process, but blood typing, HLA test, and serological testing were less accurate for determining biological relations. After the introduction of DNA testing during 80s, scientists discovered the potential of DNA testing for identifying biological relationships.

What is the process for Parental DNA Test?

DNA is the unique genetic make-up of an individual. When a baby comes in this world, the mother and father pass on half of their DNA to the baby. The baby’s DNA is a mix of the parent’s DNA with a unique sequence.

For parental DNA tests, we collect a small buccal sample of an individual, and then we obtain and examine the DNA sequence. We then compare the DNA from the samples of the alleged father or mother. The 0% matching gives a negative result. For a positive result, the probability between the parent and the child should be 99.9% or greater.

False Results

Although DNA testing process is highly advanced and we perform it very carefully, there are possibilities of false results. DNA tests from proper and certified labs and research centers have hardly any chances of false results. But the following situations can alter the results of a paternal DNA test.

  • Fraud

If the DNA paternity test is done for a legal case, either of the parties might want to get hold of the test result and tamper it. Tampering test results is nearly impossible under strict regulations and when a proper and certified lab is performing the test. However, if any party can get hold of the result, they can tamper it for their gain.

  • Lab Error

Deliberate fraud is not the only reason for false positive and negative results. Errors by the lab during the test process can also give inaccurate results. If you suspect that your test result is incorrect, this might be the reason, and you should have another test.

  • Candidates may be Related

Even if the candidates are have a relation, the DNA test will not give a 99% probability in usual cases. However,  in some instances, it is possible. If the candidate has a relation to the kid, then the lab should conduct the test very carefully, and give results double-checking to be on the safe side.

  • DNA Mutations

DNA mutations are alterations in the DNA sequence. They happen spontaneously throughout life and cause no interference in the DNA test result. But if a sperm contains a strand of DNA with mutation, the chances are that paternity test can give false negative result for  the father and child. Radioactive rays. especially from chemotherapy, and other sources can induce mutations in DNA. In such cases, using the DNA from the mother can increase the paternity index and give correct test results.

Final Thoughts

Paternal DNA tests are important when the rights and duties of parents are an issue, and the child’s paternity is in doubt. Getting paternity tests from a proper and certified lab is necessary to remove any chances of error. AABB DNA Testing offers a full range of services to validate family relations.

How to Read the Results of Your DNA Test

DNA testing has proved to be a major technological and scientific advancement. It has been used as an effective tool in determining ancestral and familial links among different groups of people. In addition to that, it has also been useful in the field of agriculture. Through the genetic marks found in every living organism, every individual stands out from its species. When testing your DNA, you have two options: to get it done through a certified testing center or do it at home with the help of DIY DNA testing kits. Both start with sample collection. Buccal swabbing is considered as a good source of sample collection.

When using a DIY kit, you should put the sample in the envelope that came with the kit. Fill in all the necessary information and send it to a laboratory of your choice for analysis. After three to seven working days, you may go and collect the results personally or have them mailed to your address. Through all these steps, it should be stressed that sample collection plays a key role in the accuracy of the DNA test, so try your best to avoid specimen contamination. Also, be careful with the testing center you choose. It is a good idea to do some research before to determine its reputation and credibility.

Go through customer feedback, ratings and reviews to get an idea. When assessing DNA (or any other genetic test), remember that every person has two different sets of genetic markers, one from their mother and one from their father. If you are assessing a paternity test, you should first look at what you and your mom have in common. The remaining genetic marker in the child must come directly from their biological dad. If the father has that same genetic marker, he is not excluded. However, if the genetic marker is absent, he is excluded.

For instance, a DNA test result appears with the genetic marker and the person tested as:

Mother – 3 4

Alleged Father – 7 6

Child – 3 6

Note that the mother takes her genetic markers of 3 and 4 from her biological parents. When we look at the child, he shares with his mother the genetic marker 3, which he inherited from her. The number 6 in the child must be from the biological father since the mother doesn’t have that genetic marker. Note that the alleged father has the number 6 genetic marker, a number that is required from the biological father. Thus, the alleged father cannot yet be charted out from the test because his genetic marker includes the number 6.

If, in the example, the alleged father had a genetic marker of 2 8, he would have been excluded from the paternity test on the grounds that he does not have the number 6.

How Long Does the DNA Testing Process Take for Immigration Purposes?

The DNA testing process has become, for the most part, much quicker than in the past. However, at AABB DNA Testing, we have seen a wide range of timeframes with regard to immigration DNA tests. We cannot provide an accurate estimate regarding how long it will take to complete immigration DNA tests, regardless of the number of people that need to be tested.

While most paternity DNA tests can be completed within a few days, the immigration DNA testing process is different and cannot be compared to paternity tests.

Why the Differences in Times and Durations?

While we cannot estimate how long immigration DNA tests will take for each individual, we can explain the process to some degree so that you can better understand why your DNA test results may take longer than other individuals or paternity tests. We understand that the visa application process can take a long time in the last thing you want are more delays.

At AABB DNA Testing, we have seen immigration DNA test cases with processing times of three weeks, even when they involved 15, 16, and even 17 family members being tested. We’ve also seen cases in which, while only two or three family members were being tested, the process took many months.

There are many reasons for this discrepancy. One of the most common is the visa application process itself. Another factor has to do with accessibility of all family members, the country in which they reside, and the shipping method used to bring their DNA sample to the United States for accurate testing.

AABB DNA Testing is committed to every single one of our clients and our main goal is to help you obtain accurate DNA tests for yourself and your sponsored family members so that you can be reunited with them in the United States as quickly as possible. However, we cannot speed up the process, but we can assure you that our DNA testing facility in New York City is one of the finest, fastest, and most reputable in the area.

If you wish to learn more about the DNA testing process, please don’t hesitate to contact one of our courteous and professional staff members at AABB DNA Testing.
