"The PCR test, it's looking for that genetic material inside the virus and you don't have to have a huge viral load to pick up for it to be sensitive and specific, meaning it functions extremely well under a variety of circumstances to include the asymptomatic as well as the symptomatic...
or PCR, tests with rapid turnaround times. Some clinics can deliver a PCR test result within hours, which these days can be as essential as a plane ticket for air travel. The downside?
The answer to that is potentially shockingly cynical:We have a vaccine now. We don’t need false positives anymore. Notionally, the system has produced its miracle cure. So, after everyone has been vaccinated, all the PCR tests being done will be done“under the new WHO guidelines”, a...
PCR Tests are by far the most widely used testing method for determining whether or not we are infected with COVID-19, but the facts presented in this 2-minute video explain why the test results are completely bogus. And if that’s true, then the numbers of infected people that the main...
Is ID now a PCR test? We conducted a large clinical evaluation of the ID NOW isothermal PCR system in a low-prevalence population and found that the ID NOW system had a positive percent agreement of 91% and a negative percent agreement of 100% compared to the Hologic Panther RT–PCR syst...
PCR conditions are the temperatures, time, and other factors that need to be met to use PCR. PCR conditions are significant when performing PCR because they affect how much DNA will be amplified and whether or not there will be many mistakes made during the process....

Why do we extract RNA and then convert it into cDNA to put in the PCR instead of just extracting DNA? Why is it important that we isolate DNA? Which of the following are possible reasons? a. To test an individual for a genetic disease....
