Which is better Elisa or PCR?
Compared to PCR, ELISA presented higher sensitivity and lower specificity. Sensitivity is an important parameter where the test is used to identify a serious but treatable disorder. Therefore, despite lower specificity, ELISA could be considered as a first-line method for detection of H. pylori infection.
Is Elisa the same as PCR? Compared to ELISA, real-time PCR showed greater agreement among duplicate samples. ELISA was found to be less time consuming and easier to perform than real-time PCR. ELISA and real-time PCR showed 100% specificity during reference sample testing.
What is the difference between PCR and antigen testing?
An antigen test is a rapid test, while the PCR test traditionally takes a few days to return results. An antigen test looks for specific proteins found on the surface of the virus, while a PCR test seeks out and amplifies the presence of the virus’s DNA material.
