What Is a Rapid Covid-19 PCR Test?

Rapid Covid-19 PCR Test

Covid-19 (sars cov 2) is a disease that took everyone by surprise. Originating from China, this disease has managed to find its way into almost every country in the world, and it has halted almost every activity.  Today many people are scared to go out because they are scared they will get infected. The road leading to a normal life all depends on curing infected people and people getting vaccinated.

In the recent week, a COVID-19 vaccine is being administerd. Other health experts are also saying testing and finding every Covid-19 infected person is another way of fighting the virus. There are many tests in the market today, but less clarity has been given on which ones are the most effective.

How many Covid-19 tests are available?

There are three different types of tests which fall under two main categories, the molecular and serology. With molecular testing, there are two types of testing, which is antibody testing and Polymerase Chain Reaction (PCR) testing. Serology testing or antigen testing falls in its category.

Molecular Testing

In the U.S, molecular testing is the fist major coronavirus testing type approved by the government. The first badge of molecular testing kits was developed by the Roche pharmaceutical company, and it has paved way for many U.S approved molecular tests to be on the market under Emergency Use Authorization (EUA).

PCR tests are the main types of molecular tests used in the country. This is a method of detecting and analyzing the genetic material (DNA or RNA) of the virus. Samples for PCR testing are collected from the throat or nose using a swab. The samples are then taken to a certified laboratory for testing and analysis.

In the past PCR testing recorded about 30% false-positive results, mainly because scientists were still learning about the effects of the virus. Now scientists know more about the virus than before, so there is a significant improvement when it comes to declaring accurate results. The speed at which results are determined has also improved. Today, results can be determined within minutes as compared to the past where it took several days for test results to be declared.

During the test, if the virus’ genetic material is detected or found, the person is considered infectious. Meaning, the person has to be isolated and treated immediately. However, when you are exhibiting symptoms but no genetic material is found, it does not mean you are not infected. It sometimes means that there was no genetic material in the sample provided. This means the genetic material is somewhere else in the body, and necessary procedures are taken to obtain such samples.

This is the reason why some patients who recover later test positive again after another test. Patients test negative because no genetic material was found in the initial sample, so doctors assume they are cured until another sample is taken for confirmation. Because of this, doctors usually test a patient twice before declaring that the patient is cured from the virus.

Getting tested for Covid-19

Covid-19 testing is one of the ways of getting back to our normal lives. The more infected patients are detected and isolated, the fewer people are infected, and the better our chances of fighting the virus. No one is obligated to get tested, but testing is the best way of knowing your status.

Some people prefer to go to the hospital after symptoms occur, which might be risky because they might end up infecting other people along the way. There are various types of test, and you must choose the one you will take. Antibody testing is not meant to detect current cases of Covid-19. It only helps to know whether your body has produced antibodies which fight the virus when you were once infected. PCR and antigen testing are used to identify the genetic materials of the virus.

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. 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

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.

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.
