COVID-19 Testing: What Do You Need to Know about Different Types of Tests

Coronavirus is one of the deadliest types of viruses that cause different types of illnesses such as SARS or severe acute respiratory syndrome, common cold, and MERS or Middle East respiratory syndrome. The outbreak of the novel coronavirus was reported in 2019 in China. 

Coronavirus also has some other names such as SARS-Cov-2 or severe accurate respiratory syndrome coronavirus 2. Remember that coronavirus is capable of affecting both humans and animals. Sometimes, the coronavirus has affected animals and created a new virus for humans. The coronavirus can lead to pneumonia, which can prove life-threatening. If you think you’re affected by the coronavirus, you need to undergo different types of tests. Here are the tests for coronavirus you need to know. 

When Do You Need to Get Tested for Coronavirus?

When you contact a health provider, they will let you know whether you need to undergo tests for COVID-19. If you think you have symptoms of COVID-19 by coming in contact with someone who has tested positive, you also need to take COVID-19 tests. 

According to MyBioSource’s recent survey, if you’ve taken the COVID-19 vaccine, you need to wait at least 5 days from your exposure to someone with COVID-19 to get testedIf you go through the COVID-19 testing before 5 days, the health providers might not be able to determine whether you have symptoms specifically to COVID-19. During this five-day probation, make sure you completely isolate yourself. Apart from wearing a mask, sanitizing your hands is also an important thing you need to remember. Even if you tested negative for COVID-19 after 5 days, it’s still best for you to continue wearing the mask until the 10th day. 

When Do You Need to Take COVID-19 Tests After Being Exposed?

After you come in close contact with someone who is affected by the coronavirus, you need to wait for 5 days before you contact a health provider for COVID-19 tests. If you think you have all the visible symptoms of COVID-19, consider testing for COVID-19 within 10 days after you’re exposed. However, if you’re affected by the coronavirus within the past 3 months, you don’t need to be tested for COVID-19 unless you have visible symptoms of this virus. 

Do You Need to Get Tested Even If You Don’t Have Symptoms but Came in Close Contact With Someone Who Has Coronavirus?

If you came in contact with someone who is COVID-19 positive, there are a couple of things you need to know. Here is the list of essential things you need to remember before you start taking COVID-19 tests:

What are the Different Types of COVID-19 Tests?

You need to go through a diagnostic test, also known as a molecular PCR test, where the medical operators will use a nasal swab so that they can collect the samples of fluids and cells from the respiratory system of your body. This way they will be able to identify the genes for the SARS-CoV-2 that can cause COVID-19. Medical operators will use a long nasal swab and insert it through your nose to reach the back of your throat. Keep in mind that PCR tests are the most effective COVID-19 test that will provide you with 100% accurate information. However, this test will take some time to generate results. 

The second one is the rapid antigen test which is one of the most common parts of rapid diagnostic tests. This test can also be done by the medical administrator with a help of a throat or nasal swab and search for a protein that is a part of the coronavirus. The time of generating results from antigen tests is not short but the test itself is also less expensive. However, this test doesn’t provide 100% accurate results all the time. If the infection of COVID-19 is not at its peak, the results generated from this test might come negative. Even if you go through the antigen test, make sure you also go through the PCR test to receive confirmed results. 

The last one is the antibody test, which is also known as the serology test. Medical operators will collect a sample of your blood that can help them identify the past infections that cause COVID-19. This test will search for the immunity system of the body that is capable of responding to the virus. After infection of the virus, there will be antibodies present in your blood. 

What Happens When You Are Tested COVID-19 Positive?

Apart from starting the medications, you need to contact your health care provider as soon as you’re tested COVID-19 positive. Make sure you notify all the people who were near you for the past couple of days so that they can watch for symptoms and get tested for COVID-19.
