With the deadly coronavirus claiming a number of human lives across the world, many people are being tested to see if they are tested positive or negative for COVID-19.
Five tests are generally carried out in labs by medical personnel to test if one is infected by coronavirus.
These tests include Swab Test, Nasal Aspirate, Tracheal Aspirate, Suptum Test and a Blood Test.

To conduct a Swab Test, a sterile cotton swab is used to collect a sample of secretions from the back of a throat and the sample is then tested by medical personnel to detect whether one tests positive or negative for COVID-19.
For the Nasal Aspirate, a sample of the secretions of the nose are collected in a tube which is then removed with gentle suction.
For the Tracheal Aspirate, a sample from inside the lungs is collected with the help of a thin, lighted tube called the bronchoscope.
For the Suptum Test, a variation of mucus from the lungs is collected and it can be coughed out or sampled from the nose with a swab.
A sample of blood will be collected in order to conduct the Blood Test.
The common signs of coronavirus include respiratory symptoms, fever, cough, sore throat and difficulty in breathing.
