Misconceptions about DNA paternity testing

In this article, we debunk some of the most common misconceptions surrounding DNA paternity testing. 

1. Paternity testing is invasive and dangerous – involving invasive procedures/sample collection

Paternity testing is neither invasive nor dangerous. 

To perform a paternity DNA test, such as those offered by AlphaBiolabs, a cheek cell DNA sample is collected from the child and the alleged father(s) using a swab, which is rubbed gently and painlessly on the inside of each sample donor’s cheek.

This simple, pain-free method of sample collection means that the test can be performed on anyone of any age, from new-born babies to older children and adults, with no risk whatsoever.

2. A paternity test can only be performed after a baby is born

It is entirely possible to perform a paternity test before a baby is born. 

A prenatal paternity test – also known as a non-invasive prenatal paternity or NIPP test – can be performed as early as seven weeks into pregnancy, making it possible to verify the identity of the biological father while the mother is still pregnant. 

This type of paternity test is also 100% risk free for all sample donors taking part in the test, including the mother and unborn baby. 

For a NIPP test, three samples are required:

  • a blood sample from the mother’s arm
  • two buccal (cheek) swab samples from the mother and 
  • two cheek swab samples from the alleged father(s)

The laboratory will then analyse the foetal (baby) DNA that circulates within the mother’s blood and compare it to the DNA sample provided by the alleged father(s) to verify paternity.

AlphaBiolabs is the only DNA laboratory in Ireland to hold ISO 17025 accreditation for prenatal paternity testing.

3. Paternity testing is only accurate up to 99%

The AlphaBiolabs Paternity Test is 100% accurate and reliable, based on the samples we receive at our laboratory. We test up to 45 DNA markers (loci), so you can be confident of getting an accurate result. 

AlphaBiolabs works to internationally-recognised standards for laboratory testing, and our laboratory holds ISO 17025 accreditation, meaning that our customers can have complete confidence as to the reliability of our paternity test results.

4. Home paternity tests are not reliable

Advancements in DNA technology mean that home paternity tests offer a 100% accurate and reliable way of verifying the identity of a child’s biological father.  

Reputable testing laboratories, such as AlphaBiolabs, ensure peace of mind at-home paternity test kits include detailed, easy-to-follow instructions for DNA sample collection. 

When followed, this ensures samples are collected correctly for analysis at the laboratory, providing reliable results.  

Factors that can affect the reliability of a paternity test result include: 

  • If someone tries to ‘cheat’ the test by deliberately submitting incorrect samples. This will obviously deliver a false result. 
  • If the test swabs are accidentally or deliberately contaminated in any way. This will result in the need to retake the test. 

Additionally, testing laboratories cannot know if the samples being submitted are from the correct people and a level of trust is therefore needed between the people requesting and taking part in the test. 

AlphaBiolabs utilises the latest market-leading DNA technology and operates in line with rigorous industry standards for DNA testing. We have performed over ONE MILLION genetic tests since 2004, so you can be assured that our award-winning laboratory will provide the answers you need.

Please note: the results of a peace of mind at-home paternity test are for your information only and cannot be used in court or for other official matters. If you require a DNA paternity test for legal purposes, you will need to instruct us for a Legal DNA Test.
