INTRODUCTION
The novel coronaviruses belong to the β genus. COVID-19 is an acute respiratory infectious disease. People are generally susceptible. Currently, the patients infected by the novel coronavirus are the main source of infection; asymptomatically infected people can also be an infectious source. Based on the current epidemiological investigation, the incubation period
is 1 to 14 days, mostly 3 to 7 days.
Respiratory syncytial virus (RSV) belongs to the genus Pneumovirus of the family Paramyxoviridae. It can be infected by coughing and air droplets, mainly causing lower respiratory tract infections such as bronchiolitis and pneumonia in infants under 6 months, and upper respiratory tract infections such as rhinitis and cold in older children and adults, and bronchitis or pneumonia in the elderly.
Adenovirus infection can lead to respiratory tract, gastrointestinal tract, urinary tract and other related diseases, such as pharyngitis, pneumonia, conjunctivitis, cystitis and so on. Adenovirus infection has been a large-scale epidemic, can have adverse effects on the health of the population, causing fever, cough, sputum, throat congestion, eyes red, dry itching, vision loss, diarrhea, vomiting and other discomfort, respiratory symptoms are severe, can appear breathing difficulties, and even asphyxia and other serious consequences.
Mycoplasma pneumoniae (MP)can cause acute respiratory infection, clinical manifestations of headache, fever, dry cough, sore throat, muscle pain and other symptoms. All age groups are infected, but young and middle-aged people and children under 4 years of age have higher rates of infection. 30% of infected people will have a whole-lung infection. Mycoplasma pneumoniae can also cause non-respiratory diseases, such as meningitis, encephalitis, pancreatitis and so on.
Influenza viruses (Flu) are the pathogens that cause influenza. Influenza is an acute respiratory infection caused by influenza A, B, and C viruses. Influenza A virus often appears in epidemic form and can cause a worldwide influenza pandemic. Influenza B virus often causes local outbreaks and does not cause a worldwide influenza pandemic. Influenza A/B viruses (Flu A/B) can cause acute respiratory infections, and people are generally susceptible.
These viruses are highly contagious, spread quickly, have a short incubation period, and have a high incidence. The main symptoms are fever, dry cough, fatigue, etc. Therefore, the joint detection of COVID-19, RSV, ADV , MP and FLU A/B has relatively great clinical findings.
PRINCIPLE
These tests use colloidal gold immunochromatography to detect COVID-19, RSV, ADV , MP and FLU A/B antigens. The test of COVID-19 use COVID-19 monoclonal antibody (test line T) and goat anti-chicken polyclonal antibody (control line C) immobilised on a nitrocellulose strip. The burgundy colored conjugate pad contains colloidal gold conjugated to another COVID-19 monoclonal antibody. When the processed buffer containing the sample is added to the sample well, COVID-19 will combine with the COVID-19 monoclonal antibody conjugate to form an antigen-antibody complex. This complex migrates through nitrocellulose membrane by capillary action. When the complex meets the line of the COVID-19 monoclonal antibody of test line T, the complex is trapped forming a burgundy colored band which confirms a reactive test result. Absence of a colored band in the test means negative test result.
The test of RSV use RSV monoclonal antibody (test line T) and goat anti-chicken polyclonal antibody (control line C) immobilised on a nitrocellulose strip. The burgundy colored conjugate pad contains colloidal gold conjugated to another RSV monoclonal antibody. When the processed buffer containing the sample is added to the sample well, RSV will combine with the RSV monoclonal antibody conjugate to form an antigen-antibody complex. This complex migrates through nitrocellulose membrane by capillary action. When the complex meets the line of the RSV monoclonal antibody of test line T, the complex is trapped forming a burgundy colored band which confirms a reactive test result. Absence of a colored band in the test means negative test result
The test of ADV antigen use ADV monoclonal antibody (test line T) and goat anti-chicken polyclonal antibody (control line C) immobilised on a nitrocellulose strip. The burgundy colored conjugate pad contains colloidal gold conjugated to another ADV monoclonal antibody. When the processed buffer containing the sample is added to the sample well, ADV will combine with
the ADV monoclonal antibody conjugate to form an antigen-antibody complex. This complex migrates through nitrocellulose membrane by capillary action. When the complex meets the line of the ADV monoclonal antibody of test line T, the complex is trapped forming a burgundy colored band which confirms a reactive test result. Absence of a colored band in the test means
negative test result.
The test of Mycoplasma pneumoniae (MP) use MP monoclonal antibody (test line T) and goat anti-chicken polyclonal antibody (control line C) immobilised on a nitrocellulose strip. The burgundy colored conjugate pad contains colloidal gold conjugated to another MP monoclonal antibody. When the processed buffer containing the sample is added to the sample well, MP will combine with the MP monoclonal antibody conjugate to form an antigen-antibody complex. This complex migrates through nitrocellulose membrane by capillary action. When the complex meets the line of the MP monoclonal antibody of test line T, the complex is trapped forming a burgundy colored band which confirms a reactive test result. Absence of a colored band in the test means negative test result.
The test of Flu A/B is coated with influenza A virus monoclonal antibody (test line A), influenza B virus monoclonal antibody (test line B) and goat anti-chicken polyclonal antibody (control line C) on a nitrocellulose membrane. The gold label pad contains another influenza A virus monoclonal antibody and influenza B virus monoclonal antibody coupled with colloidal gold. When a sample containing influenza A virus antigen is added to the sample well, the influenza A virus antigen will combine with the influenza A virus monoclonal antibody conjugate to form an antigen-antibody complex. The complex moves through the nitrocellulose membrane. When the complex encounters the influenza A virus monoclonal antibody on the test line A, the complex is captured and forms a burgundy band, which confirms the positive test result.
When a sample containing influenza B virus antigen is added to the sample well, the influenza B virus antigen is the same as that of influenza A virus antigen. The influenza B virus antigen will color the test line B, forming a burgundy line, that is, confirm Influenza B virus positive test result. No color band on test line A/B means negative test result.
The test kit contains a quality control line (control line C). A purple-red line appears on the control line regardless of the
presence or absence of COVID-19, RSV, ADV , MP and FLU A/B Antigen in the sample. If the control line is not colored, it means that the test result is invalid regardless of whether the test line is colored. The control line is the criterion for judging whether the test strip is valid.

TEST PROCEDURE
Allow test cassette, Antigen Extraction Tube with Extraction Reagent to room temperature (15-30°C) prior to testing.
1.Ask the patient to remove the secretions on the surface of the anterior nasopharynx, keep the head slightly tilted, and gently and slowly insert the swab through the nasopharynx to the nasopharynx, When resistance is encountered, it will reach the posterior nasopharynx, stay for a few seconds to absorb secretions, and gently rotate to remove the swab.
2. Put the swab specimen into the Antigen Extraction Tube with Extraction Reagent, and rotate the swab about 10 times while pressing the swab head against the tube wall to release the antigen in the swab, then let it stand for about 1 minute.
3. Remove the swab while squeezing the tip of the swab so that as much liquid in the swab can be discharged as possible. Dispose of used swabs in accordance with biohazard waste disposal methods.
4. Install the dripper on the Antigen Extraction Tube with Extraction Reagent and cap it tightly, and let it stand for about 1 minute.
5.Open the aluminum foil bag and take out the test card, add 3 drops (about 100μL) into the sample hole of the test card (or use a pipette to add 100μL), and start the timer.
6. Wait for the colored line to appear. The result should be read after 15 minutes. Do not interpret the result after 20 minutes.
