Hand Use Antiseptics

Healthcare Personnel Handwash & Handrub

Nelson Labs Bozeman has been closely involved in the development and refinement of the health care personnel handwash and health care personnel handrub testing methods used to evaluate handwash and handrub products for health care personnel.

The general concept of the test is to determine how effectively handwash and handrub products can eliminate transient, contaminative bacteria from the hands. Either Serratia marcescens (S. marcescens) or Escherichia coli (E. coli) generally serves in the role of the transient, contaminative bacteria. Broth suspensions of the organisms are applied to the hands of the test subjects, after which the test product is applied. Other organisms may be used per a sponsor’s request.

Along with testing the testing of the product’s ability to eliminate the challenge microorganism, a skin irritation assessment evaluates the effect of the product on the test subject’s skin.
