During the COVID-19 pandemic, over sixty antigen diagnostic tests for SARS-CoV-2 were granted Emergency Use Authorization by the FDA. While new lateral flow antigen tests were critical in expanding global testing capacity, the rapid adoption highlighted some unique challenges, including demonstrating adequate sensitivity. Today, inactivated, whole organism QCs for antigen tests can be used by diagnostic developers to better evaluate the performance of their assays, contributing to higher quality tests.  
 
Reach the highest confidence in your antigen-based assays
ZeptoMetrix^® PROtrol™ is a new line of products designed for antigen-based diagnostic methods for infectious diseases, including lateral flow immunoassays. PROtrol is an inactivated whole organism that mimics a true clinical specimen. The reported specific protein concentration and TCID50 minimizes reagent qualification testing and decreases the need for repeat testing to save time and money.
