Should I take a DNA test?

🎧 Listen to this article

Whether you should take a DNA test (e.g. a paternity test) depends on your personal circumstances, what you’re hoping to learn from taking the test, and how you intend to use the test results.

In this article, we discuss whether you should take a DNA test, the reasons people need DNA tests, and the implications of taking a test.

What is DNA testing?

DNA testing provides a simple, accurate way of verifying biological relationships between individuals.

DNA relationship tests – the type of DNA tests we offer at AlphaBiolabs – work by analyzing and comparing DNA samples to identify matching DNA markers between individuals.

Why do people need DNA testing?

When we talk about DNA testing, many people will automatically think about paternity testing – one of our most popular DNA tests, used to verify the biological relationship between a potential father and a child.

However, there are many other reasons why you might need a DNA test, including:

For a sense of identity

If you have questions about your family tree, finding out the truth about your biological relationships can help to establish or reinforce a sense of identity.

This can include anything from confirming who your biological parents are, to establishing whether siblings are full or half-siblings, or whether siblings from multiple births are identical or non-identical.

An insight into health

If you are thinking about starting a family, or are curious about your own health, understanding your family tree can provide peace of mind, or enable you to seek testing, diagnoses and treatment for hereditary illnesses.

If you have questions about your parentage or biological relationships, you may be missing out on this valuable information. In these circumstances, DNA testing can be hugely helpful.

Twin DNA (zygosity) testing can also be useful for this purpose. Because identical siblings share the same DNA profile (barring some minor variations), it is possible for these siblings to be born with the same health conditions.

If one sibling from a multiple birth has been impacted by illness, it can be helpful to know whether siblings are genetically identical, especially for parents who might want to get multiple siblings tested for the same condition.

Settling inheritance disputes

Where a family member has passed away and a surviving relative wishes to make a claim to their estate, a DNA test can be used to confirm a biological relationship.

This is most commonly seen in cases where a child wishes to make a claim to their deceased father’s estate, and paternity is in dispute.

However, it is important to note that a peace of mind DNA test, such as those offered by AlphaBiolabs, would not be suitable for settling an inheritance dispute.

This is because the results of a peace of mind DNA test are for your information only and cannot be used for legal matters or in court proceedings. For inheritance disputes, you would need a legal DNA test.

DNA testing after fertility treatments

With increasing numbers of babies being born as a result of fertility treatments like in vitro fertilization (IVF) and sperm donation, DNA testing can provide peace of mind as to the biological identity of a child’s parents.

Because the fertilization process or implantation process takes place in a clinic or hospital, there is a small risk of mistakes happening, and the wrong sperm sample or embryo being used during the procedure.

For this reason, individuals or couples who conceive using fertility treatments may decide to perform a prenatal paternity test while the mother is still pregnant, or a paternity test or maternity test after the baby has been born for added reassurance that the procedure has been performed correctly.

Whatever your reasons for needing a DNA test, we would always recommend that you think carefully about your reasons for wanting a test before ordering.

It is also worth considering the potential impact of the results, both on your own personal wellbeing and on your interpersonal relationships.

Is consent needed for a DNA test?

For a DNA test to be performed, consent must be given by or on behalf of each person providing their DNA sample for testing.

Anyone aged 16 or over must provide their own consent (a signature). For children under the age of 16, parental consent is required from an adult with parental responsibility for the child.

Without this consent, a DNA test cannot be performed.

Is there an age limit for DNA testing?

There is no age limit or minimum age at which a child can take a DNA test.

In most cases, a DNA test simply requires cheek swabs to be rubbed painlessly on the inside of the cheek to collect cheek cell DNA.

This pain-free method of sample collection means that DNA testing can be performed on a person of any age, from new-born babies to grown up children and adults.

Although there is no age limit for DNA testing, it is important to think about why you want or need a DNA test, and what the outcome of the test could mean for you and your family.

What are the different types of DNA test?

There are many types of DNA test available, to meet a range of needs. The types of DNA test that we offer at AlphaBiolabs include:

• Paternity DNA Testing – used to verify a biological relationship between a child and a potential father
• Maternity DNA Testing – used to verify a biological relationship between a child and a potential mother
• Prenatal Paternity Testing – used to verify a biological relationship between a potential father and a child, while the mother is still pregnant
• Prenatal Gender Testing – used to determine the gender of an unborn baby while the mother is still pregnant
• Twin DNA (Zygosity) Testing – used to determine whether children from multiple births are identical or non-identical (fraternal)
• Sibling DNA Testing – used to determine whether two or more individuals are full siblings or half siblings
• Grandparent DNA Testing – used to establish a biological relationship between a child and one or more of their biological grandparents, which in turn can help verify a biological relationship between a child and their father or mother
• Aunt and Uncle DNA Testing – also known as avuncular tests. These tests are used to establish a biological relationship between a child and their potential aunt or uncle, which in turn will help verify a biological relationship between a child and their father or mother
• Single Genetic Profile Testing – a type of DNA test that allows an individual to obtain a record of their DNA profile
• Y Chromosome (Y-DNA) Testing – used to verify a relationship between potential male relatives by identifying matching Y chromosomes
• Viability DNA Testing – a DNA viability test or viability study is often performed where discretion is required for the DNA test. This type of testing involves extracting a DNA sample from an alternative source (other than cheek swab samples) such as a used toothbrush or nail clippings

Should I get a paternity test?

There are many situations where a paternity test might be wanted or needed. However, the decision to order a test is often not an easy one to make.

Whether you are a mother who is unsure about the identity of your child’s father, a man with doubts over whether you are the father of a child, or you require a paternity test for another reason, the question of whether you should get a paternity test is likely going to lead to uncomfortable conversations.

Before ordering a paternity test, it is important to consider your personal circumstances.

It can often be helpful to weigh up the pros and cons of doing the test, including how you will feel if you do not get the result you want, and the impact that the result of the test could have on family relationships.

If you do decide you want or need to go ahead with a paternity test, it is important to discuss the decision with everyone involved.

This is crucial, as you must have the appropriate consent from or on behalf of each person submitting their DNA samples for testing.

Any person over the age of 16 can provide their own consent for their DNA to be used in testing. If testing a child under the age of 16, consent must be provided by a parent or guardian with parental responsibility for that child.

Other factors to consider include your relationship to the child in question, and how their parent/guardian will react to the suggestion of a paternity test.

For example, if you are the potential father who wants to start a conversation about paternity testing with the child’s mother, it is important to approach the conversation rationally and without accusation. Explain your reasons for wanting the test calmly and remember to stay respectful.

If you are a mother who has doubts over the paternity of your child, starting the conversation around paternity testing with the potential father can be very difficult.

It is important to consider the impact on the family, including your child, if you do not get the result you want. If you do decide to do a paternity test, you should explain that you want the test for the wellbeing of your child and that you have their best interests at heart. You may also want to discuss what happens next, depending on the results.

While these conversations are likely to be upsetting, it is important to have them so you can make decisions about your family’s future.

In some cases, it can also be a good idea to seek counseling to help all parties deal with the aftermath of the results.

What are the reasons for getting a paternity test?

There are many reasons why you might want to get a paternity test, including:

A sense of identity

If you have questions about your heritage, understanding your biological relationships can help you to establish a sense of identity.

If you have lived for many years without knowing who your father is, a paternity test can be an ideal solution, providing answers to long-standing questions.

You want to learn more about your family’s medical history

If you are thinking about starting a family, have questions about your family’s medical history, or are just curious about your own health, understanding your family tree – including who your biological father is – can provide valuable information about any hereditary illnesses.

It can also enable you to seek testing, diagnosis, and treatment, if needed.

You have doubts about the paternity of your unborn child

Knowing who a child’s father is before the baby is born can help ensure the father and child bond gets off to the best possible start.

It can also help you make important decisions about your child’s care before he or she arrives. In these circumstances, a non-invasive prenatal paternity (NIPP) test is a 100% safe, and risk-free way of establishing paternity while the mother is still pregnant.

Inheritance, wills, and probate

The question of a person’s paternity can become even more significant when a family member passes away, and important decisions need to be made regarding their estate.

In circumstances where a child wishes to make a claim to their deceased father’s estate – and paternity is in dispute – a paternity test can help verify a biological relationship between father and child.

However, it is important to note that a peace of mind DNA test, such as those offered by AlphaBiolabs, would not be suitable for settling an inheritance dispute.

This is because the results of a peace of mind DNA test are for your information only and cannot be used for legal matters or in court proceedings. For inheritance disputes, you would need a legal DNA test.

Where a child was conceived via a sperm donor or other fertility treatments

Paternity testing can also be used to provide peace of mind as to the biological identity of a child’s father after fertility treatments like in vitro fertilization (IVF) and sperm donation.

Because the fertilization process takes place in a clinic or hospital, there is a small risk of mistakes happening, and the wrong sperm sample being used during the procedure.

For this reason, if you are an individual or couple that has conceived using fertility treatments, you might want a paternity test while the mother is still pregnant (prenatal paternity test) or after the baby has been born (paternity test), for added reassurance that the right man is the biological father.
