In vitro sensitisation assay approved for validation

SenzaGen’s test Genomic Allergen Rapid Detection (GARD) has been reviewed by all OECD WNT (The Working Group of the National Coordinators of the Test Guidelines Programme (WNT)) task force members and has been included in the Test Guideline Programme.

This means that the process of formally validating GARD can begin. The purpose of the validation process is to show that GARD is a reproducible assay that can be used by external laboratories. The assay will be transferred externally to perform a so called ‘ring trial’.


“This is a very important decision for the development of GARD as an international sensitisation test and we are very confident we will have a successful ring trial. Even if our customers have been convinced by the quality of our test, it will make a big difference from a regulatory point of view when the test is validated,” said Senzagen CEO, Anki Malmborg Hager.


The GARD test has been scientifically validated and has gone through successful in house validations prior to this with industrial partners. The test assay is based on a new innovative genomic technique which is argued to be the future of sensitisation testing now that animal bans are more and more prevailing. As the chemical industry needs to find accurate and reliable tests, GARD will be an important player on the testing market once it has finalised its validation.

“The OECD WNT representatives were very interested and positive to the GARD test and to include it in the TGP work plan. The representatives also look forward to receiving information regarding the formal validation, when these results are available. The demand is high for new alternative test methods and it has been an interesting journey as a representative for Swedish Chemicals Agency (Kemikalieinspektionen) to present GARD to OECD as it has such great potential. I am very much looking forward to follow the future for this test,” said Henrik Appelgren, national coordinator at Kemikalieinspektionen. 

Two external laboratories will now test GARD on several different chemicals to confirm that the test is reproducible. This process has started and final validation is expected within one year.
