Understanding How Reliable are Cheek Swab Tests for Alleged Paternity?



Cheek Swab Tests

Did you know that the genetic testing market is expected to reach $32.83 billion by 2029?

Genetic testing is the process of analyzing DNA to determine an individual’s genetic predisposition. It can also determine genetic relationships, such as paternity.

One type of genetic test for paternity is a cheek swab test. This non-invasive and simple procedure has gained popularity in recent years. This is due to its convenience and affordable cost.

In this article, we will dive deeper into the reliability of cheek swab tests for alleged paternity. Continue reading to learn more.

Understanding the Science Behind The Swab Tests

Cheek swab tests are also known as buccal swab tests. It involves taking a sample of cells from the inside of an individual’s cheek using a cotton tip applicator. These cells contain DNA which can be analyzed for genetic testing.

The collected sample is then sent to a laboratory where it undergoes a polymerase chain reaction (PCR) process. This process amplifies and copies specific regions of DNA. The amplified DNA is then analyzed to identify genetic markers unique to each individual.

These genetic markers are then compared between the child and the alleged father. This is to determine if they share a biological relationship. The results of this comparison can provide evidence of paternity with up to 99.9% accuracy.

Factors That Affect Reliability

The swab tests have a high accuracy rate. However, certain factors can affect the reliability of the results. These include:


During the collection of samples, it is crucial to avoid contamination. This can occur if the swab touches another person’s DNA. It can also occur when it comes into contact with food, drink, or tobacco.

Contamination can also happen in the laboratory if proper protocols are not followed. This can result in incorrect results and affect the reliability of the test.

Sample Quality

The quality of the collected sample is crucial to obtaining accurate results. If there are not enough cells, it can affect the PCR process and lead to inconclusive results.

It is essential for individuals undergoing a cheek swab test to follow instructions carefully. Failure to do so can result in a poor-quality sample and unreliable results.

Chain of Custody

Chain of custody refers to the documentation and tracking of a sample from collection to analysis. It is important for legal paternity tests. It ensures that the samples have not been tampered with or switched.

If proper chain of custody procedures are not followed, it can raise doubts about the reliability of the results. It is crucial to choose a reputable and accredited laboratory for cheek swab testing. To help you with this, you can click to get a paternal test here.

Paternity test results can have significant legal implications. They are often used in cases related to:

  • Child custody
  • Child support
  • Inheritance
  • Immigration

In legal cases, the reliability of the results is vital. This is why it is crucial to follow proper procedures and choose a reputable laboratory for testing.

Cheek Swab Tests: Proving Paternity

Cheek swab tests are a reliable option for determining paternity. However, certain factors can affect their accuracy and reliability.

It is important to follow instructions and choose a reputable laboratory for testing. If you have any doubts about the results, it is always best to seek professional advice. Paternity testing can have significant implications, so it is essential to ensure accurate and reliable results.
