Virus and Virucidial Testing

The virucidial test measures the efficacy of virudicial disinfectants. Efficacy data must be provided to register a virudicial disinfectant for market release. Nelson Labs has experience testing many different virucidial disinfectants against an assortment of viruses, including herpesvirus 1 (HSV1), human coronavirus, and HIV.

This testing is done in compliance with ASTM E 1052 and ASTM E 1053. Test methods may be modified to meet your testing needs. Viruses may be acquired as necessary. Our scientifically sounding test includes tight controls that can give clients a high level of confidence in their test results.

Study Outline

The virus is dried on a carrier (hard non-porous surface, such as glass) and treated with a disinfectant. The virus is recovered and allowed to infect host cells. Infection is observed by Cytopathec Effect (CPE). the infectious virus titer is measured by 50% Tissue Culture Infective Does (TCID50) for carriers before and after treatment. The log reduction is determined for the disinfectant.
