This product is used for in vitro qualitative detection of influenza A and influenza B virus protein antigens in human swab test samples. The InfluenzaA+B antigen combined rapid test kit is designed to detect and identify influenza A and influenza B virus nucleoprotein antigens. Antigens can generally be detected in nasopharyngeal specimens during the acute infection stage.
A positive result indicates the presence of viral antigens, but the clinical correlation with the patient's medical history and other diagnostic information is necessary to determine the infection status. A positive result does not exclude bacterial infection or co-infection with other viruses.
A negative result does not exclude influenza A or influenza B infection, and should not be used as the sole basis for treatment or patient management decisions, including infection control decisions. Negative results must be combined with clinical observation, patient history and epidemiological information, and confirmed by molecular diagnostic analysis, and used for patient management when necessary.
The InfluenzaA+B antigen combined rapid test kit is only for testing in medical institution. This product is for professional used only.
Influenza is a contagious respiratory disease caused by influenza viruses. It can cause mild to severe diseases. The severe consequences of influenza infection can lead to hospitalization or death. Some people, such as the elderly, young children, and people with certain health conditions, are prone to severe flu complications. There are two main types of influenza viruses: type A and type B. The influenza A and B (human influenza viruses) that are usually spread among people are the cause of seasonal influenza epidemics every year.
Reagent cassette: The test kit includes the flu A+B test strip, which are fixed in a plastic device;
Cell preservation solution (phosphate buffer containing surfactant);
A swab (customized according to customer needs);
One bag of desiccant;
One extraction tube;
Note: The components in the kits of different batch numbers cannot be used interchangeably.
Equipment and materials required for testing but not provided: timer, gloves, goggles.
• Store at 2 ~ 30 º C in the sealed pouch for 24 months.
• Keep away from direct sunlight, moisture and heat.
• DO NOT FREEZE.
Sample Collection&Storage
Specimens obtained early in the onset of symptoms will contain the highest virus titer; Compared with RT-PCR testing, specimens obtained 5 days after the onset of symptoms are more likely to produce Positive results; Insufficient specimen collection, improper specimen handling and/or transportation may produce false negative results; Do not return the nasal swab to the original swab packaging;
Freshly collected specimens should be processed as soon as possible, but no later than 1 hour after specimen collection;
The collected specimens can be stored at 2-8°C for no more than 24 hours;
Store at -70ºC for a long time, but avoid repeated freeze-thaw cycles; Improper sample handling, storage and transportation methods may produce false negative results.
This product can be equipped with disposable sampling swabs, sampling is as follows:
Nasal Sampling: Gently insert the swab head into the nasal cavity and scrape the cavity wall.
Immerse the swab head into sample solution and discard the tail of swab.
DETECTION
1. Add about 10 drops (300µl) or full bottle of buffer into the extraction tube.
2. Collect the swab sample according to above instruction.
3. Roll the swab at least 6 times while pressing the head against the bottom and side of the extraction tube.
4. Leave the swab into the extraction tube for 1 minute.
5. Squeeze the tube by fingers from outside of the tube to immerse the swab. Remove the swab. The extracted solution will be used as test sample.
6. Put the tip on the tube and tighten up.
7. Add 2 drops (50µl) of the mixed sample to both sample holes of the cassette and read the results in 15 minutes.
