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.

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.
