The Coronavirus is a group of germs that can cause several deadly diseases, including COVID-19, SARS, and MERS. These viruses can be fatal for both humans and animals. Sometimes, one strain of virus gets transformed into a new strain with deadlier power. Hence, people need to be tested to detect the presence of Coronavirus even if they do not suffer from any prominent symptoms of this infection. A rapid antigen test is essential for a traveler before getting into a flight for his/her destination.
Symptoms of infection caused by Coronavirus
Generally, high fever, cough and cold, breathing problems, soreness of throat, and severe headache are the common symptoms of all diseases caused by Coronavirus infections. Most of these symptoms strongly resemble those of common flu, for which it is difficult to diagnose accurately without a rapid antigen test. Some people also suffer from asymptomatic COVID-19, which should be detected at the earliest to stop the spread of this disease to other people around them.

Usually, the results of rapid antigen tests are quite accurate in the assessment of the presence of viruses. Though some people have the opinion that traditional lab tests are more accurate in detecting viruses, the usefulness of rapid antigen tests is proved by experts now. All rapid antigen tests can more or less accurately find the presence of Coronavirus or other similar deadly germs in the human body.
Usually, people are inflicted by this virus when they come in close contact with people suffering from diseases caused by Coronavirus. Hence, it is advised to maintain social distancing with all and to avoid crowded places as much as possible, to prevent this infection. Even healthy people are advised to sanitize their hands frequently with alcohol-based sanitizer or wash hands with soap and water, to eliminate all germs from the hand surface.
Ways of fluid collection for a rapid antigen test
Generally, doctors and lab technicians conduct a rapid antigen test by collecting body fluid from the patient in any of the following ways.
Nasal fluid test – Firstly, mild saline solution is passed into the nasal cavity. Then this solution is lightly sucked back from the nose, which should contain Coronavirus if the patient is already infected.
Blood test – A sample of the patient’s blood is drawn from a vein running on his/her arm. This blood is tested in the laboratory to check whether it contains any kind of infectious germ, like Coronavirus.
Swab test – The sample of the swab is taken from the throat or nasal cavity of the patient, as Coronavirus is mostly present in the respiratory tract of the patient. This swab is scrapped from the mucous lining of the respiratory passage.
Sputum test – When a person coughs forcefully, dense mucus called sputum may come out of his/her mouth. This mucus accumulates in the lungs and this condition intensifies due to viral infection. The sputum is collected in a container and sent to the laboratory for a rapid antigen test. Sometimes, sputum can also be collected from the nasal cavity of a patient.
Tracheal fluid test – A bronchoscope is a thin tubular device provided with a torch, which is passed through the mouth up to the trachea and lungs. It derives sputum from the lungs that can be used as a sample to be tested in the laboratory.
These tests also help in detecting the presence of antibodies, the density of which depends on the age of the patient, his/her health condition, and medicines currently taken to cure certain illnesses.
