Pharyngeal swab detection is a medical detection method, which uses a medical cotton swab to dip a small amount of secretion from the pharynx of the human body, inoculate it in a special Petri dish, and then place it in a device that can control the temperature for culture. It can understand the patient's condition, oral mucosa and pharyngeal infection.

　　Objective: to take secretion from pharynx and tonsil for bacterial culture or virus isolation.

　　Materials: throat swab culture tube, alcohol lamp, match, tongue depressor, flashlight.
