What is the reason? If it is a pathogen, first of all, there will be a detailed bacterial name. Secondly, there will be drug sensitivity tests.

Of course, nothing is absolute. Normal flora will also be mixed with harmful bacteria (this is normal). When the human body is not sick, a few harmful bacteria will not reproduce. It's just mixed with normal flora. In fact, larynx is different from other organs. Because of breathing and eating, it is an open organ. The normal flora living in the throat is very complicated.

However, when an unexpected situation occurs, such as the invasion of cold virus, which leads to a cold, the ecological environment of laryngology has changed, and the throat has an inflammatory allergic reaction due to the invasion of cold virus. It may lead to the differentiation of bacteria that used to live normally, and some harmful bacteria begin to multiply. So it leads to conditional disease,-double infection. At this time, there will be more bacteria, not a small number, which will appear in the form of+. For example, if pneumococcus originally mixed with normal flora grows, the inspector will conduct a drug sensitivity test on the bacterium.

Often the culture of drug sensitivity test is the result of the culture of harmful bacteria. However, a small number of culture results without indicating bacterial subjects and drug sensitivity tests are normal in the eyes of doctors. Of course, this also needs to be combined with the judgment of clinical condition. Sometimes, the culture results may be inconsistent with clinical symptoms. The cultured bacteria are normal, but the virus cold exists (the virus can't be cultured). If there is any virus infection, just look at the routine blood reference. So doctors will make a choice to treat viral colds.
