The principle of pharyngeal swab test is:

normal human pharyngeal culture should be normal oral flora, and no pathogenic bacteria growth, pharyngeal bacteria are from the outside world, under normal circumstances do not cause disease, but in the body systemic or local resistance and other external factors can be infected and cause disease, therefore, pharyngeal swab test can isolate pathogenic bacteria, help diphtheria, purulent tonsillitis, acute pharyngitis and other diagnoses.

A pharyngeal swab is a small amount of secretion taken from the human pharynx with a medical flocked swab, and the sample taken is the pharyngeal swab specimen.

In order to test for the type of virus in respiratory diseases, the throat swab is often used to detect the type of virus easily, quickly and accurately. If pathogenic bacteria are detected in the throat swab, it is considered a respiratory infection and can be combined with other tests (X-ray fluoroscopy, ultrasound, etc.) to diagnose the site of respiratory tract infection.

If yeast is cultured, consider whether antibiotics were used inappropriately or in excess during the infection, and stop using antibiotics immediately and switch to antifungal drugs, such as amphotericin B, ashwagandha, clotrimazole, etc.
