DNA Testing to Prove Family Relationships

Family DNA testing is quite common, especially as it’s the perfect answer to all your family-related questions. Some people get this DNA test to kill their curiosity, and some have to do it for their documentation. The court might be demanding it, or your immigration and visa officer might request it. DNA testing helps confirm biological maternity, paternity, and your other family relationships. Families that consist of mixed races or those that don’t have proper documents usually get this. There are different types of relationship DNA testing. To learn more about family DNA testing, read further below.

Family DNA testing

Maternity Test

The purpose of a maternity test is to determine your biological mother. Every human being inherits half of their DNA from their biological mother and the other half from their biological father. A maternity DNA test proves if the mother has the same genes as the child. If she doesn’t, then it is a clear answer that she isn’t the biological mother. You may not need this test if you’re already getting a paternal test.

Sibship Test

You can easily determine the relationship between your siblings through a family DNA test. People carry out Sibship tests when they want to find out their relationship with another person. This DNA test works regardless of sex. You can also find out whether they’re your full or half-sibling.  If two siblings share the same DNA, then the genetic marker should be at least 50%. For half-siblings, the marker is at 25%.

According to these markers, lab technicians can then determine the chances if the siblings share the same DNA. A sibling DNA test isn’t 100% accurate as it’s hard to determine with certainty. However, the results are always on a likelihood scale.

Y Chromosome Testing

When it comes to paternity testing, it has a lot to do with the Y chromosome. Y chromosome passes on to males from a father to a son. With the help of these tests, you can determine if two men are from one paternal line. This line consists of siblings, cousins, uncle/nephews, and others. Even though this test links to a specific family line, it is still not very accurate. For example, it doesn’t have the ability to distinguish between brothers, paternal sons, cousins, and grandsons.

The samples from males go through polymorphic sites and then are compared. If the males share a common Y chromosome and are from the same paternal line, the test will come out positive. DNA paternity testing is around 100% accurate if conducted under the right procedure. The male handling has to be very effective when proving paternity test results.

Other Relationship Testing

You can also determine the biological relationship with your cousins, uncles, aunts, and grandparents through family DNA testing. These tests use DNA identification technology. Most of the results for this type of test occurs on the basis of likelihood. Therefore, there is a slight chance of an inconclusive result.

Reasons Why You Would Need To Get a Family DNA Test

Family DNA testing also helps with many official requirements and documents. These tests can also be for health purposes, knowing if you’re prone to a life-threatening disease. Mentioned below is the reason why you would need to get a family DNA test:

1.     Surrogacy Purposes

Surrogacy pregnancy may require testing, especially if the biological mother wants to confirm if the child is still hers. This is very common in gestational surrogacy cases. The DNA testing for this case will usually take place after the delivery of the baby. On the other hand, you can also carry out a prenatal test.

2.     Immigration Purposes

The USCIS has not made DNA testing mandatory. However, if there is no proof of the biological relationship between the people sponsoring you, there are further steps. The Visa counsel will advise you to get a family DNA test to gather more accurate proof. These tests have nothing to do with making the immigration process faster. All it does is remove any breaks and unanswered questions to get the process going.

3.     Adoption Purposes

If a mother wants to put her child up for adoption, then there will be a maternity test. Orphanages usually conduct these tests to prove that the mother is the biological mother of the child.

4.     Personal Purposes

You can also achieve a family DNA test for your own curiosity, especially when you haven’t got the right answers or documented proof. DNA tests bring you one step closer to finding out your roots if you’re not sure of them.

Family DNA Testing: The Bottom-Line

DNA testing surely does helps prove family relationships to a certain extent. That is especially the case if they are your immediate families like your mother, father, and siblings. You may need this test for different purposes. Therefore, if you plan on getting one, get in touch with AB DNA Testing Services in New York.

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.

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.
