Common reasons for DNA testing

DNA tests serve a variety of purposes, from satisfying personal curiosity to fulfilling critical legal requirements. Here are some of the most common reasons why people turn to DNA testing for answers:

• Verifying biological relationships

  DNA testing provides a 100% accurate, reliable way of verifying biological relationships between family members, with some of the most popular DNA tests including paternity, maternity, sibling tests and aunt/uncle (avuncular) tests.

  These tests can provide peace of mind, resolve disputes, or bring clarity to personal situations.

• Legal purposes
  DNA testing is commonly used in legal matters to prove biological relationships for a variety of purposes, including for family law cases (child custody or financial disputes), birth certificate changes, immigration and naturalisation purposes, inheritance disputes, and child welfare proceedings.
• Ancestry
  Ancestry DNA testing has grown in popularity in recent years, with more people wanting to learn about their ancestors, and the journeys they may have taken thousands of years ago.

Knowing what you’re looking for from the test can help you decide which DNA test is best for you.

Relationship DNA Testing

These tests can help you verify biological relationships between family members.

At AlphaBiolabs, we offer a range of DNA tests for peace of mind and for legal purposes.

• Paternity and Maternity Testing: these tests can be used to determine whether there is a biological relationship between a child and their alleged father or mother.
• Prenatal Paternity Testing: this non-invasive and 100% risk-free test is used to verify paternity before a baby is born/while the mother is still pregnant.

• Sibling Testing: our Sibling DNA Test can confirm if two or more people are full or half siblings.
• Avuncular DNA Testing: our Aunt DNA Tests and Uncle DNA Tests can confirm a biological relationship between a niece or nephew and a potential aunt or uncle. Avuncular tests are commonly used to confirm paternity or maternity where the biological father or mother is unavailable to take a parentage DNA test (paternity/maternity).
• Grandparent DNA Testing: a Grandparent DNA Test is used to confirm a biological relationship between a grandchild and their potential grandparent. As with aunt/uncle DNA tests, these tests are often used to verify paternity or maternity where the biological mother/father is unavailable for testing.
• Baby Gender Test: this test can be used to find out the sex of a baby from as early as 6 weeks into pregnancy. As with our Prenatal Paternity Test, it is 100% safe and risk-free for mother and baby.
• Twin DNA Testing: a twin DNA or zygosity test will you whether twins are identical, non-identical, or potentially semi-identical. The test is not exclusive to twins but can also be performed on up to five siblings from the same birth.  
• Y Chromosome Testing: a Y chromosome or Y-DNA test will tell you if there is a biological relationship between two or more males. This test cannot be used to determine how individuals are related (e.g. father and son, grandfather and grandson), but rather whether they are paternally related. This is because the Y chromosome is passed down from father to son.

Ancestry Testing

We offer three types of ancestry DNA test to suit your needs.

• DNA Origins Ancestry Test: this test can tell you where your ancestors are likely to have originated from.
• Paternal Lineage Ancestry Test: this test can help you find out more about your ancient paternal heritage (father’s side).
• Maternal Lineage Ancestry Test: this test looks at your mitochondrial DNA (mtDNA) to reveal your ancient maternal heritage (mother’s side).

How to choose the right DNA test

Selecting the right DNA test depends on your specific goals and circumstances. Below are just a few things you should consider when purchasing a DNA test.

Purpose

• Personal knowledge: If you are looking for a test for your own peace of mind, you can choose any of our at-home DNA tests. Simply order your kit online and follow the instructions included in your test kit to collect your sample and return it to our laboratory for analysis.
• Legal needs: If you require a DNA test for legal matters, you will need a legal DNA test. This is because the DNA samples for a legal test must be collected under strict chain of custody conditions for the test results to be court admissible.

Speed of results

We know that ordering a DNA test can be an emotional time, depending on the type of test you need. That’s why we prioritise rapid results, so you can get the answers you’re looking for as soon as possible.

We offer results in 2-3 days for most of our DNA tests.

Reputation of the testing company

With so many options available, it can be difficult to know which company you can trust to deliver 100% accurate, reliable DNA results.

You can find out more about the testing company by reading reviews and testimonials from previous customers and reviewing the company’s accreditations.

AlphaBiolabs is ISO 17025-accredited and ISO 9001 certified.

Testing accuracy

A good indicator of DNA testing accuracy includes the number of DNA markers analysed during testing, as well as the company’s accreditations and certifications.

AlphaBiolabs’ industry-leading DNA tests can analyse up to 45 DNA markers, allowing for even more genetic material to be analysed, strengthening the results of the test.

This is especially useful for complex relationship tests (sibling, grandparent, aunt, uncle) where the chance of obtaining a conclusive result will always be lower than the more straightforward paternity or maternity tests, as the DNA has not been directly inherited.  

Privacy and confidentiality

DNA testing involves sensitive personal information, so choosing a provider that prioritises your data security is important.

We guarantee strict confidentiality throughout the testing process, with all correspondence kept 100% private and confidential.

We’ve also invested heavily in cyber security, so your personal information is secure and will NEVER share your DNA results or personal data with third-party organisations or DNA matching services.

Cost

It’s important to find a test that fits your budget, however it’s also worth considering what’s included with the cost of the test.

AlphaBiolabs has worked hard to offer a range of tests that are affordable, without compromising on accuracy or quality. All pricing for our peace of mind at-home DNA tests (including ancestry) includes the cost of your test kit, shipping your test kit, and laboratory analysis.
