Testing for viral penetration of non-latex surgical and examination gloves: a comparison of three methods - sciencedirect

We found that thin gloves manufactured from polyethylene or polyvinyl chloride are ineffective barriers while gloves of thin latex are superior but not without failure. Ask an expert for a specific consultation on your product. Additionally, this test has been used by textile manufacturers to qualify their product for sale as raw material to medical device manufacturers. Examination gloves worn for protection from biohazards were sampled and evaluated for their ability to exclude virus particles.

Viral penetration gloves. After 1 minute of applied pressure, the pressure is released and the specimen then sits for an additional 54 minutes at atmospheric pressure. Overall, the two methods in which bacteriophage were placed inside the gloves provided more sensitivity than the method in which bacteriophage was spiked into broth outside the gloves. Latex, although permeable to ethanol, was penetrated by virus less than 1% of the time regardless of whether the latex had been pre-exposed to disinfectant or not. Thus the placement of bacteriophage inside test gloves (or the use of pressure across the glove barrier during testing), and the use of a standardised stress protocol, will improve significantly the ability of a glove test protocol to determine the relative quality of the barrier offered by medical examination and surgical gloves. Three protocols for the direct examination of the viral barrier properties of non-latex gloves were compared with 1080 gloves (270 gloves from each of two surgical brands and two medical examination brands). We provide a one-stop shop for all pb70 testing. Vpt110: price is per sample.

This test is required by aami pb70 guidance to determine the level of protection for gowns and drapes. This study highlights the need for caution on the part of those who rely upon examination gloves for protection from infectious agents as well as the need for establishing more adequate standards and testing procedures for their manufacture. Include 4 extra samples for setup.
