All You Need To Know About COVID-19 Rapid Antigen Test

COVID-19 Rapid Antigen Test

COVID-19 is a dreadful disease caused by the virus of the SARS-CoV-2 family. The majority of virus-infected individuals will have mild to severe respiratory disease and will recover without the need for special care. However, some people will get severe illnesses and need to see a doctor.

Serious symptoms are more likely to strike aged individuals and those with underlying medical conditions such as cancer, diabetes, heart disease, or chronic respiratory issues. COVID-19 can cause anyone to get ill or pass away at any age.

When humans breathe air polluted by the virus’s droplets and minute airborne particles, COVID-19 can spread. These can be breathed across longer distances, especially indoors, but the risk is most significant when individuals are close together. Transmission may also happen if infected fluids spill or spray into the eyes, nose, mouth, or, less frequently, via contaminated surfaces.

Even if they do not have symptoms, people can spread the virus for up to 20 days. But, if this virus is detected on time, its harmful effect can be prevented. Fortunately, two effective lab tests are available to confirm COVID-19 disease: RT-PCR and antigen test. There are many trusted PCR and antigen test pharmacies.

Before moving forward, let us dive into both lab tests that confirm COVID-19.


This COVID-19 test, also known as a molecular test, uses a laboratory method named reverse transcription polymerase chain reaction to identify the virus’ genetic material. A medical expert will take a fluid sample from the back of your nose by inserting a thin and long nasal swab (nasopharyngeal swab) into your nostril. A very short or shorter nasal swab (mid-turbinate swab) can be used to gather a sample (anterior nares swab). A long swab may occasionally be inserted into the back of your throat by a medical expert (oropharyngeal swab). Alternatively, you can spit into a tube to collect a sample of saliva.

If examined on-site, you may get outcomes in a few minutes. On the other hand, if a sample is transferred to an outside lab, the results may take one to three days or longer. When correctly conducted by a medical specialist, RT-PCR assays are pretty accurate; however, the quick test may miss some instances.

Antigen Test

Specific proteins in the virus are found using the COVID-19 assay. Some antigen tests can yield findings only a few minutes after collecting a fluid sample using a long nose swab. Others could be taken to a lab for examination.

A positive antigen test result is accurate when procedures are faithfully followed.

Why Is COVID-19 Test Done?

You may need to go to an antigen test pharmacy if:

  • You experience signs of COVID-19 as a fever, cough, exhaustion, or shortness of breath.
  • You were close to someone who has COVID-19. The Centers for Disease Control and Prevention (CDC) advise being tested at least five days after the exposure, even if you don’t have any symptoms.
  • If you have not fully immunized yet, your healthcare practitioner, another healthcare expert, or your local public health department suggests a test.
  • Some colleges or places of employment may need you to take a test as part of the screening process.
  • You intend to be near someone with a high risk of developing severe COVID-19 disease, and your community has a medium or high risk of COVID-19 spreading.

However, even when a test could be advised, you might not require one if you haven’t experienced any symptoms and have had COVID-19 within the last 30 days.

Diagnostic testing is given significant importance to a few populations. Those with COVID-19 symptoms and indications include:

  • working as first responders or in a healthcare facility
  • Live or work in nursing homes, other long-term care institutions, or other settings where people are kept in close quarters, such as jails or shelters.
  • are receiving medical attention in a hospital

Depending on the rules set forth by the local health authority for the surveillance of COVID-19 in certain localities, other persons may be given priority for testing.

Some COVID-19 patients might not exhibit any symptoms (asymptomatic). However, they still have the ability to distribute COVID-19 infection to other people. It is possible to test someone who has no symptoms. If a positive test result is obtained from an asymptomatic person, they should adhere to self-isolation instructions to prevent the virus from spreading.

Depending on where you reside and the advice of your local public health experts. COVID-19 diagnostic testing may not be available where you live or at all.

How To Prepare For COVID-19 Antigen Test?

Plan to wear a face mask to and from the testing facility or your provider’s office regardless or not you are experiencing symptoms.

  • Call your doctor’s office or the local health department if you believe you have COVID-19 to discuss your symptoms and determine if testing is available before you visit. Staff members can then wear personal protective equipment and prepare for your visit.
  • Consider being tested if you have no symptoms but have been in intimate interaction with someone who has COVID-19. Ask your doctor or the public health agency for testing guidance. Having a COVID-19 test at least five days after having close contact with someone infected with a virus is preferable. If you visit an antigen test pharmacy very soon, it might not catch the virus.

What To Expect 

A medical expert collects saliva, mucus from your nose or throat, or both, for a COVID-19 clinical diagnosis. A sample for a lab test can be collected at a healthcare provider’s office, a medical facility, or a drive up-test.

Throat Or Nose Swab-:

Although a short or brief nose or throat swab is permissible, a long nasal swab (nasopharyngeal swab) is advised. To obtain a sample of mucus, a medical professional inserts a thin, flexible stick with cotton at the tip into your nose or runs the swab along the back of your throat. This could be uncomfortable.

Sample Of Saliva-:

Some places provide testing using saliva. While a saliva test is simpler to do and frequently less painful. It may be somewhat less sensitive than a mucus sample obtained with a long nose swab. You spit into a container numerous times to submit a sample of your saliva for testing. Before being delivered to a lab for analysis, the container is sealed.

The Bottom Line-:

It was all about COVID-19 testing. Don’t delay and schedule a slot at a rapid antigen test pharmacy to realize the signs of Coronavirus.
