Swab refers to a small group of absorbent material (such as cotton) that wraps around the end of the stick. Used for dressing or for wiping on a certain area. It is usually used as a medical examination tool for collecting microorganisms, exfoliated cells or secretions.
Because the breath and food pass through the mouth, there are all kinds of bacteria in the mouth. Such as caterpillar, various staphylococcus, various streptococcus, diphtheria-like bacillus, klebsiella pneumoniae and escherichia coli. Influenza spreads through the respiratory tract, and the pharynx is where the virus is concentrated. Throat swab specimens use a medical swab to take a small amount of secretions from the body's pharynx. Samples are taken using a suction sponge swab. To test for respiratory disease virus types, the type of virus can be easily and quickly detected through a throat swab.
