Through polymerase/enzyme mixes, molecular tests amplify specific nucleic acid fragments and provide highly specific and accurate test results with only a small amount of samples, which is very helpful for real-time monitoring of the disease. However, the current standard molecular detection takes 2-3 hours. Antigen rapid screening, the alternative to PCR tests, is simple and fast, but cannot detect a small amount of antigens or samples in the early stage of infection. That is why we TrustBio start to develop a molecular test that is as easy to use as the Antigen Rapid test, while reserving both sensitivity and accuracy. EZCheck series then was born.
