SpletFirst, PCR testing is more sensitive than other methods, such as antigen tests. This means that PCR tests can detect lower levels of the virus in a sample, making them more reliable for detecting infection. Additionally, PCR tests have a greater accuracy rate because they are able to detect mutations in the virus that other tests may miss. SpletWhat Is Real-Time PCR? In conventional PCR, the amplified DNA product, or amplicon, is detected in an end-point analysis. In real-time PCR, the accumulation of amplification product is measured as the reaction progresses, in real time, with product quantification after each cycle.
