Cito Test for influenza diagnosis is a rapid test for the qualitative detection of influenza A and B virus antigens in nasal swabs for the purpose of influenza diagnosis.
For self-control.
The test for detecting influenza A and B virus antigens has a sensitivity and specificity of >99% compared to other rapid tests.
Review
Influenza is an acute respiratory viral disease transmitted by droplets, characterized by an acute onset, a predominant lesion of the upper respiratory tract and general intoxication. Influenza is by far the most common infectious disease in the world and occurs every year in the cold season. Every season, millions of adults and children around the world get sick with influenza, and hundreds of thousands of patients die from complications.
The flu virus mutates easily, so new strains emerge every year that the world's immune system has not yet encountered. The infection can affect large populations in a short period of time - a large city will be infected within 1.5-2 weeks, and a huge country - within 3-4 weeks.
People of all ages are susceptible to infection, especially those with weakened immune systems. Cold, stress, anxiety, emotional and physical tension, alcohol abuse weaken the immune system and weaken the body's defenses. Children over 65 years of age, pregnant women and people with chronic diseases are at risk, as they have a very high risk of developing adverse health effects.
Complications of influenza are a serious threat to human health and life. These include itching, sinusitis, otitis media, meningitis, and complications of chronic diseases. To avoid complications, it is important to diagnose influenza in a timely manner and seek medical attention.
CITO TEST® Flu is a rapid test for the qualitative detection of influenza A and B virus antigens in nasal swabs for the purpose of diagnosing influenza.
Features
The test for the detection of influenza A and B virus antigens is a qualitative rapid test with visualization of test results.
The principle of the test is based on the specific binding of antibodies to the antigen.
During testing, the sample reacts with reagents that have been pre-applied and dried on the test membrane. The mixture then migrates down the test under capillary forces.
In the case of a positive result, the reagents present in the test result zone capture the mixture, resulting in the appearance of red and/or blue test lines.
The mixture will continue to move along the membrane to the control section, where a green control line always appears.
The presence of a control line is confirmation of a sufficient amount of sample used, filling of the membrane capillaries, as well as an internal quality control of the reagents.
Accessories
Materials provided: Test cassette; tube with solvent; sterile swab; Instructions.
Materials needed but not provided: disposable gloves; watch.
Methods of application
Remove the cotton swab from its packaging. Tilt your head back with your chin lifted high. Insert the sterile cotton swab into one nostril and gently rotate it several times, touching the walls of your nose to get as many cells as possible, not just mucus. Then remove the swab from the nostril.
Remove the cap from the dropper bottle and place the swab with the sample into the bottle. Mix the liquid with the swab by rotating it vigorously in the bottle at least 10 times.
Squeeze the walls of the tube to extract the maximum amount of liquid from the swab. Remove and discard the swab. Close the tube cap.
Testing procedure
Remove the test from the sealed package immediately before performing the test. Please note that the test cassette has two windows.
Place the test tube with the results window facing up on a flat surface.
Shake the tube vigorously several times and break off the tip of the cap.
Add 4 drops of liquid from the tube to the insertion well marked with an arrow or the letter "S". Read the results after 10 minutes.
Wait for the colored lines to appear in the result window. Depending on the concentration of the virus, test lines can be observed 5 minutes after sample injection. The final result should be evaluated after 10 minutes. Do not observe the lines after 10 minutes.
Interpretation of the result
Negative result: Only one green control line "C" will appear in the result window. You are not infected with influenza A or B virus. If you develop flu symptoms within two days, repeat the test with another test. If the result is negative, consult your doctor.
Positive result for influenza A: In addition to the green control line "C", a red test line "T" (influenza A result line) appears in the result field. You are infected with influenza A and should seek medical attention immediately.
Influenza B Positive: In addition to the green test line "C" a blue test line "T" (influenza B result line) also appears in the result window. You are infected with influenza B virus and you should see a doctor.
Invalid result: No test line "C" (green) appears, regardless of whether the test line "T" (red or blue) appears. Consult a technician and repeat the testing procedure with a new test.
Note: The intensity of the red and blue lines depends on the concentration of antigen in the sample. However, neither the quantitative content nor the degree of amplification of antigens in the sample can be determined by this qualitative test.
The test must be used within 2 hours of opening the sealed package.
The test only provides a preliminary diagnosis of influenza A or influenza B. The final diagnosis should be made by a doctor after evaluating all clinical and laboratory results.
Only nasal swabs can be used as test material. Other samples (saliva, sputum or urine) cannot be used. The quality of the test depends on the quality of the collected and prepared clinical specimen.
A negative test result may be obtained if the sample amount is insufficient or the antigen content is below the sensitivity threshold of the test.
Precautions
For self-testing Do not use after the expiration date indicated on the package Do not use if the package has been tampered with. Swab samples may be considered potentially hazardous and should be handled as infected; if the swab is taken by a third party, disposable gloves should be worn After use, the test should be disposed of in a waste container Use only the kits provided with the test.
Storage conditions
The test is stable until the expiration date indicated on the package.
Do not open the sealed package before testing begins.
Keep the test in its packaging at a temperature between 2°C and 30°C.
