Polymerase chain reaction (PCR) testing identifies the presence of a pathogen’s DNA or RNA in a patient specimen. PCR is highly sensitive and specific testing that can confirm the actual presence of an organism.
NO, Our PCR includes a quantitative measure of viral load to allow discrimination between vaccine interference and natural infection with the virus.
Real-time PCR is a closed-tube system that delivers shorter assay run times, virtually eliminates false positives and provides quantitative results that are both faster and more sensitive than conventional PCR.
Very early stages, in simple words: PCR show positive in infected animals before antibody can be detected.
YES definitely, we have lots of recorded cases where the rapid test failed to detect the infection and PCR results were inclusive to save the animal's life.
