About this test

DNA free Certification allows you to confirm that products are free of various types of DNA, contaminants and inhibitors. All these can adversely affect DNA testing by interfering with the PCR technique needed to analyse it.

Results for DNA free certification are ready in 5 working days from receipt of samples at the laboratory.

Why use DNA free certification?

DNA-free certification is important in a laboratory setting as it guarantees the accuracy and validity of DNA test results. Anything from forensic analysis to parentage and relationship testing would require all lab reagents and solutions to be free of any contaminant. Potential contaminants could include human DNA and ensuring samples are free of all foreign human DNA is a critical part of any DNA test.

Companies often using DNA free certification

Companies that test their products to ensure that they are free of different types of DNA and contaminants can reassure their clients of the integrity and purity of their products.

Certifying products human DNA-free is common amongst:


  • Laboratory plastics manufacturers
  • Medical device manufacturers
  • Pharmaceutical companies

Accuracy of DNA free certification

Many other companies tend to use agarose gel electrophoresis which enables the separation of DNA fragments depending on their size. Agarose gel electrophoresis is effective at separating macromolecules like DNA, RNA and proteins. Our partner DNA laboratories use a more advanced technique that allows for higher levels of sensitivity than the more commonly used fluorescent labelled probes. The technique used is fluorescent labelled probes and are evaluated on a capillary electrophoresis platform to ensure accurate results with a test sensitivity of 1 pg.
