Introduction
Influenza (commonly known as ‘flu’) is a highly contagious, acute viral infection of the respiratory tract. It is a communicable disease easily transmitted through the coughing and sneezing of aerosolized droplets containing live virus.1 Influenza outbreaks occur each year during the fall and winter months. Type A viruses are typically more prevalent than type B viruses and are associated with most serious influenza epidemics, while type B infections are usually milder.
Intended use
ACCU-TELL® Influenza A+B Cassette (Swab/Nasal Aspirate) is a rapid chromatographic immunoassay for the qualitative detection of influenza A and B antigens in nasal swab or throat swab or nasal aspirate specimens. Also called influenza swab test, it is intended to aid in the rapid differential diagnosis of influenza A and B viral infections.
Specimen collection and preparation
Nasal swab sample
Insert a sterilized swab into a nasal cavity securely from a nostril and collect muco-epidermis wiping turbinate several times.
Pharyngeal swab sample
Insert a sterilized swab into pharynx and collect muco-eoidermis mainly wiping flare region of post-pharyngeal wall and palatine tonsil several times, and be careful not to make saliva attach to the swab.
Nasopharyngeal aspirate
Connect an aspiration catheter to an aspiration trap that is attached to an aspiration device, insert the catheter to nasal cavity from a nostril, start the aspiration device and then collect nasal aspirate sample. Dip a sterilized swab into the collected nasal aspirate sample and make the specimen cling to the swab.
Allow the test, specimen, extraction buffer to equilibrate to room temperature (15-30°C) prior to testing.
1. Remove the test cassette from the sealed foil pouch and use it within one hour. Best results will be obtained if the assay is performed immediately after opening the foil pouch.
2. Place the Extraction Tube in the workstation. Hold the extraction reagent bottle upside down vertically. Squeeze the bottle and let the solution drop into the extraction tube freely without touching the edge of the tube. Add 8 drops of solution (Approx. 0.3mL) to the Extraction Tube. See illustration 1.
3. Place the swab specimen in the Extraction Tube. Rotate the swab for approximately 10 seconds while pressing the head against the inside of the tube to release the antigen in the swab. See illustration 2.
4. Remove the swab while squeezing the swab head against the inside of the Extraction Tube as you remove it to expel as much liquid as possible from the swab. Discard the swab in accordance with your biohazard waste disposal protocol. See illustration 3.
5. Fit the dropper tip on top of the extraction tube. Place the test cassette on a clean and level surface. See illustration 4.
6. Add three drops of the solution (approx.80ul) to the sample well and then start the timer. Read the result at 8 minutes. Do not interpret the result after 15 minutes.
Performance characteristics
Sensitivity, Specificity and Accuracy
ACCU-TELL® Influenza A+B Cassette (Swab/Nasal Aspirate) has been evaluated with specimens obtained from the patients. RT-PCR is used as the reference method for ACCU-TELL® Influenza A+B Cassette (Swab/Nasal Aspirate) Specimens were considered positive if Cell Culture indicated a positive result.
