There are several conventional sampling methods

a) Nasal swab: gently insert the swab head into the nasal palate in the nasal canal, stay for a moment, and then slowly rotate the line to exit. Swab the other nostril with another swab, immerse the swab head into the sample solution, and discard the tail.

b) Pharyngeal swab: wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with a swab. Similarly, immerse the swab head into the samplingbest alat rapid test antigen - UDXBIO solution and discard the tail.

c) Gargle: gargle with 10ml normal saline. When gargling, let the patient's head lean back slightly, make an "Oh" sound, let the normal saline rotate in the pharynx, and collect the lotion with 50ml empty sample tube.

d) Nasal lotion: the patient takes a sitting position, slightly tilts his head back, injects 50ml normal saline into one nostril with a pipette, and instructs the patient to make a K sound at the same time to close the pharyngeal cavity. Then let the patient lower his head to make the normal saline flow out, collect the lotion with a 50ml empty sampling tube, and repeat this process to wash the nostrils on both sides.

e) Nasopharynx extract: this method is often used to collect tracheal and bronchial secretions. A collector connected to a negative pressure pump is used to extract mucus from the nasopharynx. First insert the collector head into the nasal cavity, turn on the negative pressure, rotate the collector head and push it out slowly. Collect and extract mucus, and rinse the collector with 5ml of collected liquid for three times.

f) Autopsy tissue samples: collect autopsy tissue samples for sample component separation when necessary. The specimens were autopsy tissues.

g) Sampling of mycoplasma, chlamydia and Ureaplasma samples: male: insert a sterile cotton swab into the urethra, rotate about 2cm, and rest for a few seconds. Female: wipe the mucus from the cervix, insert a seedling free swab into the cervix tube for 1-2cm and take samples.
