All COVID-19 tests start with a sample, but the scientific process goes very differently

after that.

At this point in the pandemic, you or someone you know has probably received

at least one COVID-19 test. But do you know which kind of test you got and the

strengths and weaknesses of these different tests?

Two major types of tests are used to diagnose infection with SARS-CoV-2:

molecular tests – better known as PCR tests – and antigen tests. Each detects a

different part of the virus, and how it works influences the test’s speed and relative

accuracy. So, what are the differences between these types of tests?

PCR tests are extremely accurate but require special lab equipment – like the PCR

heating machine seen here – and can take hours or days to perform.

Looking for genetic evidence

The first step for either kind of test is to get a sample from the patient. This can be

a nasal swab or a bit of saliva.

For PCR tests, the next step is amplification of genetic material so that even a small

amount of coronavirus genes in the patient’s sample can be detected. This is done

using a technique called a polymerase chain reaction. A health care worker takes

the sample and treats it with an enzyme that converts RNA into

double-stranded DNA. Then, the DNA is mixed with a solution containing an

enzyme called a polymerase and heated, causing the DNA to separate into two

single-stranded DNA pieces. The temperature is lowered, and polymerase, with the

help of a small piece of guide DNA called a primer, binds to the single-stranded

DNA and copies it. The primers ensure that only coronavirus DNA is amplified.

You’ve now created two copies of coronavirus DNA from the original one piece of RNA.

Laboratory machines repeat these heating and cooling cycles 30 to 40 times, doubling

the DNA until there are a billion copies of the original piece. The amplified sequence

contains fluorescent dye that is read by a machine.

The amplifying property of PCR allows the test to successfully detect even the smallest

amount of coronavirus genetic material in a sample. This makes it a highly sensitive

and accurate test. With accuracy that approaches 100%, it is the gold standard for

diagnosing SARS–CoV–2.

However, PCR tests have some weaknesses too. They require a skilled laboratory

technician and special equipment to run them, and the amplification process can

take an hour or more from start to finish. Usually only large, centralized testing

facilities – like hospital labs – can conduct many PCR tests at a time. Between sample

collection, transportation, amplification, detection and reporting, it can take from

12 hours to five days for a person to get results back. And finally, they aren’t cheap

at $100 or more per test.

Rapid Antigen tests

Rapid, accurate tests are essential to contain a highly contagious virus like SARS-CoV-2.

PCR tests are accurate but can take a long time to produce results. Antigen tests,

the other major type of coronavirus test, while much faster, are less accurate.

Antigens are substances that cause the body to produce an immune response –

they trigger the generation of antibodies. These tests use lab-made antibodies to

search for antigens from the SARS-CoV-2 virus.

To run an antigen test, you first treat a sample with a liquid containing salt and soap

that breaks apart cells and other particles. Then you apply this liquid to a test strip

that has antibodies specific to SARS-CoV-2 painted on it in a thin line.

Just like antibodies in your body, the ones on the test strip will bind to any antigen

in the sample. If the antibodies bind to coronavirus antigens, a colored line appears

on the test strip indicating the presence of SARS-CoV-2.

Antigen tests have a number of strengths. First, they are so easy to use that people

with no special training can perform them and interpret the results – even at home.

They also produce results quickly, typically in less than 15 minutes. Another benefit

is that these tests can be relatively inexpensive at around $10-$15 per test.

Antigen tests do have some drawbacks. Depending on the situation, they can be

less accurate than PCR tests. When a person is symptomatic or has a lot of virus in

their system, antigen tests are very accurate. However, unlike molecular PCR tests,

antigen tests don’t amplify the thing they are looking for. This means there needs to

be enough viral antigen in the sample for the antibodies on the test strip to generate

a signal. When a person is in the early stages of infection, not a lot of virus is in the

nose and throat, from which the samples are taken. So, antigen tests can miss early

cases of COVID-19. It’s also during this stage that a person has no symptoms, so

they are more likely to be unaware they’re infected.

Understanding the strengths and limitations of both PCR and antigen tests, and

when to use them, can help to bring the COVID-19 pandemic under control.

So, the next time you get a COVID-19 test, choose the one that is right for you.

COVID-19 RAPID ANTIGEN TEST

The COVID-19 rapid antigen test detects protein fragments specific to the

Coronavirus. Rapid antigen testing is a faster way to detect if you have a current

COVID-19 infection. Rapid antigen testing may be helpful for those who want

quick results to meet a testing requirement for an event or travel. For example,

this test can be used if you plan to visit a location or establishment that requires

testing prior to arrival. Testing requirements vary by location and may change

over time. This test requires a nasal or nasopharyngeal swab. With our product

testing, results may come back in as soon as 10 – 15 minutes.

Common COVID-19 symptoms include fever, cough, and shortness of breath.

How the test works?

A sample is collected through a nasal or throat swab and mixed with

a solution. The solution is then placed onto an indicator device that may

detect the presence of the virus that causes COVID-19.

Test Purpose: Used to detect an active infection.
Sample Type: Nasal or Nasopharyngeal Swab
Results Time: 10 – 15 Minutes*

                          (Wait times may vary depending on volume)

Rapid antigen tests offer a quick and easy way to screen for COVID-19 at home.

In about 15 minutes, they detect active infections via a nasal swab, including in

asymptomatic individuals. Often called “rapid tests” or “at-home COVID tests,”

these rapid antigen tests can be a valuable tool for managing life during the pandemic

—if you can get your hands on one.

Rapid antigen tests are used as a test to diagnose COVID-19.

This means that if you test positive using a rapid antigen test, your result

does not need to be confirmed with a PCR test.

In only 15 minutes, you will have the results you need to confidently return to work,

school, sports and all the things you love to do, with the ability to store and share

our family's and your test results from Renji Antigen Rapid Test.

With Renji COVID-19 Antigen Rapid Test, you can test yourself after being out in

public. Early and regular testing helps you better care for yourself and protects

your friends, family, and community members from potential exposure.

This kit is intended to be used for the qualitative detection of SARS-CoV-2 antigen

in human respiratory specimens, sputum, and other samples. This kit uses cellulose

membrane immunochromatography technology.
Antigen detection is used for auxiliary diagnosis or epidemiological investigation

of human infection with SARS-CoV-2.

【When should I use a rapid antigen test?】

If you are a close contact, you can use an rapid antigen test for your initial and day

6 test. You can also purchase and use rapid antigen tests from us:

• before entering a high risk setting, e.g. healthcare or aged care
• before going out where there may be crowds
• before going to work, especially if it is a critical worksite
• to provide reassurance if you have no symptoms but are feeling anxious

or worried.

Accessing rapid antigen tests

If you are not a close contact, rapid antigen tests are sold commercially in

supermarkets and pharmacies.

Note: The components in the kits of different batch numbers are not interchangeable.

The materials and instruments necessary for the test but not provided are as follows:

Lancet;

Absorbent paper or similar material;

Timer;

Micropipette corresponding to the range;

Laboratory safety protection equipment such as disposable gloves, etc.

【RESULTS ANALYSIS】

The interpretation of visual interpretation results (as shown below):

1. The results can be read directly by naked eyes as shown in the figures below:

Positive result: a visible band

can be seen in both line C and line T.

2. Negative result: A visible band can be seen in line C only.

3. Invalid result: A visible band cannot be seen in line C, and the test must be

repeated using a new strip.

【MANAGEMENT OF RESULTS】

【REPORTING YOUR RESULT】

You are legally required to report all positive rapid antigen test results. You must

report your positive result if you get your test from a designated RAT Collection

Point, from a retail outlet, from your workplace or through any other means

(i.e. over the internet).

You can also report negative and invalid test results to help provide a full picture

of rates of COVID-19 testing in the state.

【WHAT DO I DO IF I HAVE A POSITIVE RESULT?】

【WHAT DO I DO IF I HAVE A NEGATIVE RESULT?】

If you are a close contact with no COVID-19 symptoms and test negative, you do not

need to get a PCR test to confirm your result.

If you have COVID-19 symptoms and test negative, you must get a PCR test to

confirm your result. Rapid antigen tests are not as sensitive as PCR tests, which

means that just because you have a negative result in a rapid antigen test, it does

not mean that you do not have COVID-19.
