Pharyngeal swab is not new to us, but do you know what diseases it is applicable to? Let's find out together

Ordinary people swallowing the isthmus need all the normal beneficial bacteria in the mouth, but need no pathogens to grow and develop. All germs in the isthmus come from outside and all normal states do not develop, but can cause diseases, including systemic or partial immune deficiency and infections under other external factors. Therefore, swallowed bacterial cultures help to isolate pathogens and diagnose diphtheria, purulent tonsillitis, acute pharyngitis, etc.

What diseases can pharyngeal swab collection be used for? Pharyngeal swabs are commonly used for clinical examination of pharyngeal bacterial or fungal inflammation such as chronic pharyngitis, mycoplasma infection, candidal pharyngitis, diphtheria, purulent tonsillitis, and acute pharyngitis.

The pharyngeal swab is mainly applied to bacterial culture, the cause of abnormal disease pathogens, when patients have recurrent sore throat, pharyngeal discomfort, itching, painful swallowing and other symptoms.

Clinical manifestations: Patients will have recurrent sore throat, throat discomfort, itching, painful swallowing, and in severe cases, the disease will become slow, headache, weakness, fever, cough, small amount of sputum, and sometimes high fever and loss of appetite.

If pathogens are detected in sputum and swallowed secretions, it is considered a respiratory tract infection. Together with other tests (e.g., x-ray fluoroscopy, ultrasound, etc.), the location of the respiratory tract infection can be diagnosed. Respiratory infections include Staphylococcus, S. pneumoniae, Haemophilus influenzae, Klebsiella pneumoniae, Staphylococcus, Streptococcus infection, Pseudomonas aeruginosa, and Escherichia coli.

Mycobacterium tuberculosis is manufactured as tuberculosis. If yeast is manufactured, consider whether antibiotics are inappropriate or excessive during the infection and stop them immediately and switch to antibacterial drugs. Examples include amphotericin B, thiamphenicol, fungal suppositories, etc.

Pharyngeal swabs are performed.

Please confirm the physician's instructions and be prepared.

Have patient rinse mouth with water, then have patient open mouth and make an "ahh" sound, using tongue plate if necessary.

Remove the disposable sample swab and gently and quickly wipe both arches, tonsils and posterior wall.

Put the head of the swab vertically to avoid touching the wall of the tube and contamination, break the tail of the swab by force at the mouth of the sampling tube bottle, throw away the tail, tighten and cap the tube (strictly aseptic operation).

Check the patient's name again after taking the sample.

Note the preservation time of the specimen and send it for examination in time.

Matters requiring attention.

When the swabber enters the tube, to avoid contamination, do not wipe the mouth of the bottle and put it in vertically. When putting into the transfer box, put it vertically to avoid leakage of liquid.

Sampling the day it is best to send to the laboratory for examination.

Before sending for inspection, the appropriate sample and checklist must be made consistent, the appearance of the sample house must be clearly known basic information, without basic information samples can not be inspected. Inspection samples must be submitted (or submitted electronically in advance) of the inspection information sheet, checklist, etc. The submitted material should be free of contamination and not put together with the sample. , sampling, in order to prevent anatomical chart, patients should avoid within 2h after meals, collection movements are light, stable and flexible to prevent patient discomfort.

Swallowing during the collection process can not touch other parts, which can ensure the accuracy of residual samples.

Decide not to use antimicrobial agents when swallowing.

The depth of pharyngeal swab collection and the length of mucosal contact time. When swallowing and swabbing, the subject has a greater reaction to vomiting, and false negatives can occur with insufficient sampling time or the use of poor swabs, and patients can delay treatment.
