It is not difficult to diagnose pneumonic influenza in combination with clinical symptoms during the epidemic period, but laboratory tests must be performed to confirm the diagnosis or for epidemiological surveillance. The gold standard method for laboratory diagnosis is virus isolation and culture. The cell culture identification cycle is 14 days, which seriously affects the timely medication guidance for patients in the clinic, and the method is limited in the clinic.

Reverse transcription-polymerase chain reaction is more sensitive compared with cell culture method, but it is expensive, takes 6 hours, and needs to be performed in a specialized laboratory, so its application in the field is limited.

To assist in clinical diagnosis of whether a person is infected with influenza virus, the Laboratory Department of the Central Hospital has introduced the Influenza A / B virus antigen detection reagent, which uses immunochromatographic technology to detect influenza virus antigen using the double antibody sandwich method to facilitate rapid detection of whether people have influenza. The test is easy to sample, safe to operate, easy to read results, and fast and effective.

Some patients or family members, especially parents of children, are distressed by their children's needles, but now parents can stop being distressed! The specimen used for our influenza virus antigen test is not blood, but a nasal aspirate, nasal swab or throat swab, and the collection process is completely non-invasive!

How are the specimens collected?

1

Nasal secretion collection: The tube on one side of the aspirator is attached to the suction pump and the tube on the other side is fully inserted into the nasal cavity through the external nostril, activating the suction pump to collect nasal fluid in the aspirator. Dip the swab into the nasal suction fluid to stain the specimen onto the swab.

2

Nasal swab collection: insert the sterilized cotton swab completely into the nasal cavity and rub the turbinates several times to collect the mucosal epidermis.

3

Pharyngeal swab collection: insert the sterilized cotton swab completely from the mouth into the pharynx, take the posterior pharyngeal wall and the reddened part of the palatine tonsils as the center and rub them several times to collect the mucosal epidermis. When collecting, be careful not to touch the saliva.
