Ever since the Covid-19 infection spread across the globe, almost every activity was put on hold. Today, countries are easing restrictions and allowing people to resume back to their old activities. People can return to school, work, and continue with their everyday life. But things are still abnormal compared to before. There is a need to follow specific guidelines like wearing a face mask and social distancing yourself from others.
All this progress has been made possible because of health professionals’ continuous efforts who risk their lives daily. Tests like the PCR and antibody tests have been made available to help combat the SARS-CoV-2 virus. Because there are many tests available, it isn’t obvious to know if you must get tested and why it is so important. This article is about PCR tests, and how relevant it is in the fight against Covid-19.
What are the various types of rapid Covid-19 tests available?
There are three various kinds of Covid-19 tests used by health experts today. They are antigen tests, Polymerase Chain Reaction (PCR) tests, and antibody tests.
Antibody tests are blood tests conducted to detect if one was infected with the virus in the past. Antibodies are produced to fight off infection detected by the immune system. Blood samples are collected either by drawing blood from the veins or by finger pricking. These tests are usually conducted on people who have been cured of the virus. The test checks if the body has produced antibodies to protect the immune system from another future infection.
Antigens are proteins found on the surface of viruses, which are easily detected by the immune system. Antigen tests are used to detect these antigens, which usually presents itself when a person has been infected and shows the virus’s symptoms. For this test, a body fluid (mucus) sample is collected using a swab from your nose or throat. When you don’t notice any symptoms, it is safer to try another test because antigen tests can sometime produce false-negative results. This test is mostly used for people whose infection is noticeable from the outside. One positive thing about antigen testing is that test results are received in a few minutes.
Samples for PCR tests are collected like that of antigen tests. The main difference between antibody tests is antibody tests are mostly used for recovered patients, while PCR tests are for active Covid-19 infection. The results for PCR tests take a few days because the samples are sent to a lab. Rapid PCR tests are also available, but they are limited and mostly used for emergencies.
Health professionals mostly use PCR tests because of their accuracy as compared to other tests. PCR tests are so accurate, most of the Covid-19 cases detected were from these tests conducted.
When to opt for rapid Covid-19 PCR tests
Choosing to take a rapid covid-19 PCR tests is essential in certain situations. The following are some of the reasons why you choose to take a rapid Covid-19 PCR test.
- When you are showing symptoms of the virus, you must get tested.
- When you are about to go back to work, testing helps to know if you have been infected to avoid spreading the virus amongst your colleagues.
- When you are having a surgery, or you are being admitted to the hospital. This prepares health professionals for any situation, depending on the outcome of your results.
- You can also get a PCR test if you are traveling for an important occasion to prevent the spread of the virus if you are infected.
If you believe you are infected with the virus and you want to get tested, you can call your local health center for information on how to get tested.
How to obtain Lab validated results
- Use a swab to sample the interior of the nasal cavity
- Apply swabbed nasal samples into a buffer solution
- Apply the buffered sample into the cuvette
- Apply COVID-19 test assay to samples for reaction
- Heat reaction for 30 minutes with Thermal Heater
- Insert heated sample cuvette into Automated Analysis Station
- Scan QR code on Automated Analysis Station for infection results
- 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. 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.
