COVID-19 continues to be a headache for many countries. Aside from that, we can see specific improvements in how healthcare professionals are handling the virus. COVID-19 is caused by the SARS-CoV-2 virus, which has caused the death of millions of people worldwide. Many laboratories and health centers are trying to find way to stop the virus. Still, until the vaccines are administered globally, testing remains the only way to detect and fight the virus.
Testing is the only way to determine whether a person is positive, whether they are showing symptoms or not. Because of how important it is, many testing methods have been developed. There are three kinds of testing that every individual is eligible to take: Polymerase Chain Reaction (PCR) testing, antibody testing, and antigen testing.
What is PCR Testing?
PCR testing is considered the gold standard of testing in the world, especially in the U.S. PCR tests are used to detect and identify any genetic material related to the SARS-CoV-2 virus. For this to be possible, samples of the fluid from the nose or throat are taken using a cotton swab. Because the virus is new, there might be some inaccuracy in the results, but generally, it produces accurate results. When someone is tested and results come out as positive, it means the person is infected with the virus and must be isolated immediately.
Testing, although helpful, has some challenges it needs to overcome. For instance, there are still some false-negative results being detected by testing kits. Even though the possibility of this happening continues to decrease, it still happens, which can be dangerous. A false-negative result is when a person actively infected with the virus tests negative. This means that the person is allowed to go home still infected with the virus and might end up infecting other people around them when they don’t self-isolate.
The time a person is tested for the virus is one contributing factor to false-negative PCR testing results. The virus produces genetic material a few days after a person is infected, so it is difficult to detect during the early stages of infection. False-positive results might also be recorded. This usually happens when a patient recovers from COVID-19. The genetic material is still present even though the person has recovered. Using PCR tests on an individual who has recently recovered with genetic material still in the system will produce false-positive results.
To avoid testing negative for COVID-19, it is advisable to isolate yourself for a minimum of 7 days when you start experiencing some of the symptoms of the virus. During this time, the virus produces genetic material that is easily detected with rapid COVID-19 PCR tests.
Are rapid COVID-19 PCR tests for everyone?
One thing to note is that everyone can opt for rapid COVID-19 PCR tests, but it does not mean the results are accurate. The reason for saying this is that PCR tests can be used on everybody, but it does not produce accurate results for everyone. PCR tests are used to detect the genetic material of the virus, which is only present when a person is actively infected. For rapid COVID-19 PCR tests to be effective, the person being tested must have an active case of the virus.
When you have recovered from the virus, antibody tests are the best option for you. Antibody tests are used to detect antibodies that fight the SARS-CoV-2 virus, meaning the presence of antibodies means you are not infected with the virus. Using PCR tests on a recovered person will only produce false-positive results because the person might still have the genetic material of the virus present in their system.

Which rapid Covid-19 PCR test kits are most reliable?
With many test kits on the market today, it is difficult to determine which of them has been approved for use. Because of this, it is crucial always to purchase testing kits from certified sources. One of the best places to find affordable and reliable rapid Covid-19 test kits is Rapid Connect Medical.
The annealing temperature (typically between 48-72°C) is related to the melting temperature (Tm) of the primers and must be determined for each primer pair used in PCR. During the extension step (typically 68-72°C) the polymerase extends the primer to form a nascent DNA strand. This process is repeated multiple times (typically 25-35 cycles), and because each new strand can also serve as a template for the primers, the region of interest is amplified exponentially. The final step of the PCR is generally a longer, single temperature step (often 5-10 min at 68-72°C) that allows for the completion of any partial copies and the clearance of all replication machinery from the nascent DNA. Once the PCR is complete, the thermal cycler is set to 4°-10°C to maintain product integrity until such time as the tubes can be removed from the machine.
Generally, if you are looking for an In vitro diagnostic (IVD) device that can quickly diagnose a COVID-19 related case, then you can bet on a rapid Covid-19 PCR test. These test devices are easy to use and they offer the greatest potential for screening asymptomatic and pre-symptomatic patients. Based on research, they have contributed a lot to the expansion of testing capabilities in the US.
The diagnostics and detection of the live virus can show a negative or positive active viral result values with high sensitivity, specificity, and accuracy. While some people may have an inhibition about the sample extraction process, but it isn’t too uncomfortable compared to other methods for other medical tests. Large numbers of a sample can be collected from a population to help identify infected persons. This data can be used for emergency guidance in stopping the community infectious spread of the virus.
The specific probability of spread of the virus from detected cases can be better observed and help modify current restrictions. “At the moment the majority of the current Covid-19 tests that all the reports are coming from are using PCR,” says University of Sussex senior lecturer in microbiology Dr Edward Wright. “They detect the genetic information of the virus, the RNA. That’s only possible if the virus is there and someone is actively infected.” Clinical and laboratory data and studies of nasopharyngeal samples have validated molecular findings and performance of rapid PCR testing. Test performed in the first few days can help stop the spread to the general public and has a direct impact on stopping the pandemic. The collection of the sample from a nasal probe swabs are easily analyzed using our rapid PCR testing solution.
When we perform quick analysis of specimens with high accuracy the risk of spread is reduced greatly. Combining this testing solution with testing for COVID-19 antibodies as well as antigen tests gives a full suite of solutions. An Antibody tests kit can show if a patient is immune to future infection. Performing different types of tests helps in solidifying findings from primary initial tests that diagnosed and identified patients with coronavirus.
If you are looking to buy large quantities of FDA EUA approved rapid Covid-19 PCR tests online, then you are safe when you get them from Rapid Connect Medical. We distribute large quantities of rapid tests across the globe at affordable prices. Bulk volume orders receive special pricing.
Rapid Connect Medical distributes various rapid Covid-19 testing kits. We are among the leading distributors of accurate, rapid Coronavirus test kits. The accuracy of any rapid testing kit depends on the sensitivity and specificity. These are important factors, especially when it comes to PCR testing. The CDC and FDA have taken care on guidance for these and other COVID-19 tests.
An efficient kit should be able to detect very low levels of the virus at the early stages of infections. High sensitivity is required to be able to capture the low levels of the virus. In the same way, high specificity is needed to distinguish the genetic materials of the virus from a sample with other genetic materials. Our kits are verified to be highly accurate with high sensitivity and specificity. We also provide detailed but easy-to-use instruction materials that anyone can understand without any special skills. This testing medium is helpful in surveillance and the study of the spread of the virus.
Our reliable Covid-19 test kits provide results within a few minutes. They also eliminate the need to transport samples to a CLIA lab. We are committed to our fight against Covid-19, and hence we supply both small and large quantities at affordable prices.
