Information About Rapid Covid-19 Antigen Tests

antigen testing

Covid-19 continues to affect our everyday activities because it continues to spread in the country and around the world. Today, health experts suggest that if we want to resume to our normal activities like going to work and school or spending time with friends and family, we have to take testing seriously. This means that there is a need to test as many people as possible to make sure all the infected people are identified and isolated from the general population.

Antigen tests have been suggested by many health experts as a way of testing thousands of people daily. Antigen tests detect any presence of viral proteins in a sample collected from the nasal cavity or saliva through a swab. They are cheap compared to other rapid Covid-19 tests, and results are attained within minutes. Antigen tests are used to identify active Covid-19 cases.

There are other antigen tests used to detect other infectious diseases like influenza and HIV, but only one antigen test has received emergency use authorization from the U.S FDA for the SARS-CoV-2, the Covid-19 virus. Some scientists like the idea that these tests are cheap and fast when it comes to getting results, but others are worried because some of the results are not accurate enough.

Antigen tests are not easy to make because it is more like trying to build an entire laboratory on a paper-like strip that must have accurate results. Most tests require the use of a bodily fluid collected from the patients using a nasal swab, then it is mixed with a sterile buffer solution (a few drops of the liquid, usually a coronavirus antigen). A few drops of the solution is placed on the end of the strip. Capillary forces pull the solution over copies of two different antibodies specific for the same viral protein. If both antibodies recognize the same target, it gives a positive result. The results are then displayed, by lines appearing or not on the test cassette.

One challenge that comes with using antigen tests is weak signals. With other genetic tests like polymerase chain reaction (PCR), the DNA or RNA sequences are amplified, which makes it easy to identify a few copies of a virus. Meaning the PCR tests are sensitive which makes it easy to detect almost every active infection. 

Antigen tests don’t have the ability to amplify their protein signal, it rather reduces the signal since it is mixed with a liquid need to allow the material to flow across the test strip. This makes the test less sensitive which usually produces a false-negative result (a false result saying a person is not infected with the virus). 

The major advantage of using antigen tests is because it does not require expensive equipment and chemicals to produce accurate results. Meaning they can be used as point-care tests for doctors, and urgent care centers or public facilities. Antigen tests are also easy to administer, so there is no need for one to be a health expert before they can administer it, but there is not a need for you to send it to a lab for processing.

Another advantage is that infected patients can be identified and isolated quickly because of the fast results. Because the tests are quick to administer, multiple tests can help confirm cases, which helps to easily identify infected people. Infected people are then isolated quickly to prevent them from infecting others. Antigen tests are also easy to manufacture in bulk as compared to other tests. Meaning more people can be tested. The advantages of using antigen test compared to the disadvantages prove that they are really essential when it comes to fighting SARS-CoV-2 virus.

The best testing kit to use

Testing is just one way of combating the virus disturbing everybody today. To make testing easier, healthcare professionals need to reliable and effective testing kits. With all the regulations put in place, it is now easy to find a variety of testing kits available on the market. 

Rapid Connect Medical is a distributor of reliable Coronavirus Antigen Test Kits. All the testing kits have been Authorized by the FDA via EUA, and it makes testing for the virus easier and faster. If you are looking to make a large purchase of Coronavirus antigen test kits or any other Covid-19 test kits online, Rapid Connect Medical is your trusted source. Feel free to contact Rapid Connect Medical for your bulk test kit orders.

Generally, rapid COVID-19 antigen tests are ideal for remote areas that lack the appropriate laboratory facilities or trained health providers to carry out molecular tests such as the PCR tests. Antigen-based tests are easy to use and require less training.  They come just in time to help remove testing backlogs and hiccups as most nations plan to ease restrictions and open up their economies.

When rapid COVID-19 antigen tests are used in populations that have a very low prevalence, false positive and negative results are more likely to occur. In such settings, a confirmation test is usually done using a PCR test, the gold standard for diagnostic testing. Authorities in Singapore are testing migrant workers using antigen tests once every week and every two weeks using polymerase chain reaction (PCR) tests.

As much as nations are testing for the COVID-19 virus, a preventive approach should be encouraged. Ordinary people should continue to keep a social distance, wear masks, and wash their hands. 

If you are looking to purchase rapid COVID-19 antigen tests from a trusted supplier online, then Rapid Connect Medical is your best bet. The company allows you to make orders of up to 10,000,000 or more FDA EUA approved COVID-19 antigen test kits. The higher the number of kits in your order, the lower the price per item.

Rapid COVID-19 antigen tests are designed for use in point-of-care or patient care settings such as emergency rooms, schools, or the doctor’s office. The FDA has authorized the use of this Point of Care (POC) antigen test in patients suspected of having contacted SARS-CoV-2. According to FDA and antigen test manufacturers, these special kits are ideal for use within five days to one week of symptom onset.

According to the FDA, the rapid COVID-19 antigen test is categorized as an in vitro diagnostic test, and it should only be used under the Emergency Use Authorization (EUA).  Most of these testing kits are only available by prescription.  Under the EUA, these tests and critical medical devices can be accessed during an emergency or when there are no adequate, approved, and available testing options.

Rapid COVID-19 antigen tests are used for the qualitative detection of the nucleocapsid protein antigen from SARS-CoV-2 in individuals suspected of coronavirus.  During the acute phase of the infection, positive results indicate the presence of viral antigens.  Positive results obtained from rapid COVID-19 antigen kits are usually highly accurate. The tests can be very specific but not as sensitive as molecular tests.

When the COVID-19 antigen test results are negative, you will need the patient’s history, clinical observations, or epidemiological information to confirm this type of status.  Since negative results are presumptive, so a confirmation test through molecular assay is crucial.  If the patient shows symptoms of COVID-19 but the antigen test shows a negative result, then a molecular test is required.

You need to be proficient in performing COVID-19 tests in point of care settings for you to use a POC rapid antigen test.  We are talking about medical professionals, clinical laboratory personnel, and trained operators.  Individuals who think that they have coronavirus disease 2019 (COVID-19) and need to get a test to verify are advised to contact their health care providers as soon as possible.
