We want to inform you that we will soon offer a new real-time PCR (qPCR) test for detection of the PRRS virus. Like our previous qPCR, this test was developed in-house.
The new test will still detect and differentiate type 1 (European) and 2 (North American) PRRS viruses in the same reaction. Although only type 2 strains have been detected so far in Canada, both types are present in many countries, including the USA. Therefore, it is important to be able to detect both types of strains and to differentiate them immediately without having to use sequencing.
Within each type of PRRS virus, a wide variety of strains are constantly evolving. This characteristic represents a major challenge for diagnostic tests such as qPCR. Compared to the previous test, the new test includes more primers and probes and their composition has been diversified. These changes provide the new test with better diagnostic and analytical sensitivities.
The concentration of the virus in the samples is interesting information in some circumstances. Until now, this was expressed in TCID50 / mL. This unit is unfortunately not very intuitive. From now on, it will rather be expressed in genomic copies / mL which should be more understandable. In addition, we will also provide the Ct values (cycle threshold) as we do for our other qPCR tests.
We are confident that this new test will meet your needs even better.
