Are Rapid Covid-19 PCR Tests Reliable?

rapid COVID-19 PCR Test

Ever since Covid-19 became a global pandemic, and the United States is one of the countries that have been affected the greatest by the virus. Testing continues to be one way of identifying infected people in many countries. Recently, a new form of tests has been released known as rapid Covid-19 tests.

Rapid tests deliver results in minutes, but there have been issues relating to the accuracy of the results compared to other Covid-19 tests. Today, improvements have been made on rapid tests, and it continues to aid in identifying infected patients. There are three types of tests used by health centers; antigen tests, PCR tests, and antibody tests.

Antibody tests help to identify if a person has come into contact with the SARS-CoV-2 virus. This test is not effective for patients who have active cases of Covid-19. Antibodies are produced by the immune system when an infection is detected. They are proteins that help fight the infection. Usually, when antibodies are seen in an individual, it means the person is no longer infected and is also protected from future infections.

Polymerase Chain Reaction (PCR) and antigen tests are diagnostic tests that help health professionals identify active cases of the virus. Currently, rapid antigen tests are available and allow significantly testing for the virus, but the rapid PCR tests are only used for emergency purposes.

Antigen tests are used to identify antigens, which are proteins found on the surface of the SARS-CoV-2 virus. Rapid antigen tests are helpful, but its efficiency rate is always questionable, mainly because it has recorded false-negative results in the past. Antigen tests are not effective when used on active patients.

What is a rapid Covid-19 PCR test?

PCR tests are used to identify the virus’s genetic material from the sample of body fluid collected from the patients either from the throat or the nose. A positive test implies that gene fragments of the virus were detected and the virus has infected you. PCR tests are the most preferred tests used by health centers, mainly because of their accuracy rate compared to the other tests.

The rapid Covid-19 PCR test is usually administered at the point of care by a licensed medical provider. A sample of the fluid in your nose or throat is collected and used for the test. Since it is a rapid test, results are delivered within the same day instead of the normal 2-3 days. Rapid Covid-19 PCR tests are not effective if one was recently affected by the virus, mainly because it will be difficult to find genetic material for the testing.

Who need a rapid Covid-19 PCR test?

As stated previously, rapid PCR tests are only administered when there is an emergency because the production of the test kits is difficult and time-consuming. The following people can get a rapid Covid-19 PCR test.

  • People who show symptoms of Covid-19
  • People who need the results before they can go to school or work
  • People traveling into the country or any state
  • People who need the results on the same day for emergency reasons

These are the primary reasons one is required to go for rapid Covid-19 PCR tests. When you test positive, you are isolated from the general population to prevent the further spread of the virus till you recover. If you test negative, you must still follow the Covid-19 tests to avoid getting infected. Some of the guidelines include;

  • Wearing face masks
  • Washing of the hands often with soap and water
  • Social distancing, usually a six feet distance
  • Use alcohol-based hand sanitizers that have at least 60% alcohol
  • Avoid getting close to people who are sick
  • Avoid going out when it is not important

A positive test implies that gene fragments of the virus were detected and the virus has infected you.

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.

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.
