Viral Testing

Perfectus Biomed specialise in viral assays, including virucidal efficacy and viral barrier testing.

Virucidal efficacy testing is important for assessing the activity of a variety of products against viruses. Testing can be carried out in a range of models including suspension tests and hard surface carrier tests. These methods can be used to assess a range of products, such as household and industrial disinfectants. Perfectus Biomed also offer viral barrier testing for wound dressings and many other materials.

Testing methods include ISO 18184, ASTM E1052, ASTM E1053, ASTM E2197 and EN 14476. GLP compliant testing is also available.

We will work with you to help you understand the different viral models, helping you to choose a method that is most suitable for both you and your product.
