How Rapid COVID-19 PCR Test Kits Work

How Rapid COVID-19 PCR Test Kits Work

The world continues to battle with the effects of the COVID-19 disease, which started from Wuhan, China. Many active cases are being detected daily with the help of rapid testing and contact tracing. Vaccines are also being developed to serve as a way of protecting ourselves from the virus. Testing is the only way to test for the virus, and many methods have been created. Antigen tests, antibody tests, and PCR tests are some of the primary forms of testing available.

Both antigen and PCR tests are used to detect active cases of the virus. Antibody tests are used to determine whether a person was once infected with the virus. Antibody tests detect whether the immune system has produced specific antibodies that fight the virus. Having COVID-19 antibodies means you were infected, but you are no longer infected. It also means you are protected from future infections, but health professionals don’t know how long that will last.

Why is testing important?

Testing is a measure used by health facilities that help to identify infected patients. When infected patients are allowed to roam, it only increases the chance of spread of the virus, which also increases the infection rate. To prevent this from happening, testing is being used as a way of finding people who have been infected.

As individuals, we must take testing seriously because it is the only way to find the virus. Another way of identifying the virus is by waiting for symptoms to show. This way is risky because, by the time symptoms start showing, it might be too late. Some people are asymptomatic to the virus, meaning they don’t show symptoms. For such a person, testing is the only way of finding out if the virus has infected them.

Importance of PCR testing

Molecular testing is one of the major testing methods being used to test for the SARS-CoV-2 virus. It is a type of technique used to analyze the biological or genetic material of the virus. Polymerase Chain Reaction (PCR) test is a type of molecular test. The first distributed batch of the test kits, approved by the Emergency Use Authorization (EUA), was developed by the Roche pharmaceutical company.  Because of how effective PCR tests are, they are considered as the “gold standard” of testing.

PCR tests are used to detect and identify the virus’s genetic material, which is the form of DNA or RNA. Samples collected for testing are taken to a certified laboratory because it can only be done by trained health professionals. PCR tests take about 2-7 days for results to be determined, but it may take longer depending on the laboratory in charge or the factors available.

A positive PCR test means the virus’s genetic material was detected, meaning the person is infected and must be isolated. When you are tested at an early stage of infection, the virus might not be seen because the virus produces genetic material after a few days of infection. This is rare, but when this happens, it usually leads to a false-negative result. That is why it is crucial to self-isolate yourself when you start feeling the symptoms of the virus before you go for testing.

Rapid molecular tests like rapid COVID-19 PCR tests have been developed for faster results. This is very helpful even though the results are not as accurate as the tests conducted in the laboratory. Rapid COVID-19 PCR tests can help test many active cases without the long waiting time for results to be determined. Using this correctly can help detect active cases quickly, which will, in turn, reduce the spread of the virus because infected patients are isolated from the general population.

Lab-Validated COVID-19 Detection Results in 8 Easy Steps

  1. Use a swab to sample the interior of the nasal cavity
  2. Apply swabbed nasal samples into buffer solution
  3. Next, apply buffered sample into cuvette
  4. Apply COVID-19 test assay to samples for reaction
  5. Heat reaction for 30 minutes with Thermal Heater
  6. Insert heated sample cuvette into Automated Analysis Station
  7. Scan QR code on Automated Analysis Station for infection results
  8. Instantly email or text results, images, notes, GPS information

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.
