Respiratory tract infections are one of the most important causes of human illness and death. There are many pathogens that cause respiratory infections, including bacteria, viruses, and mycoplasma, with viruses in particular being the most common. Although the clinical signs and symptoms of respiratory tract infections are similar, the treatment of infections caused by difffferent types of pathogens varies greatly, as do the effiffifficacy and course of the disease; therefore, rapid and accurate detection and identifification of pathogenic microorganisms can help in clinical diagnosis and treatment. Among them, the main viruses causing human respiratory diseases are coronaviruses, inflfluenza viruses and syncytial viruses.
So far, seven human coronaviruses (HCoV) causing human respiratory diseases have been identifified, including HCoV-229E, HCoV-NL63, HCoV-OC43, HCoV-HKU1, SARS-CoV, MERS-CoV, and SARS-CoV-2. Currently, SARS CoV-2 is the most infectious virus and is one of the most infectious viral pathogens of human respiratory tract infections (RTI).
Currently, patients infected with SARS-CoV-2 are the primary source of infection; asymptomatic infected individuals can also be the source of infection. According to current epidemiological investigations, the incubation period is 1 to 14 days, with most being 3 to 7 days. Clinical presentation symptoms include fever, fatigue, cough and other symptoms with respiratory distress that rapidly progresses to life-threatening severe pneumonia, respiratory failure, and acute respiratory cyst syndrome. Inflfluenza, often referred to as the flflu, is an acute respiratory infection caused by the inflfluenza virus. It is highly contagious. It is spread mainly through coughing and sneezing. It usually breaks out in spring and winter. It is mainly divided into inflfluenza A and inflfluenza B. Inflfluenza A viruses are highly variable, followed by inflfluenza B viruses.
Therefore, inflfluenza A viruses are more prevalent compared to inflfluenza B viruses. Respiratory syncytial virus is an RNA virus with an incubation period of 2-8 days, with most being 4-6 days. Most infections are seen in infants and children, more than half of whom are less than 1 year old. Initially, it may present with a cough, nasal congestion, and fever, mostly high. The high fever mostly lasts for 1-4 days, and a few may last up to 5-8 days. Diseases such as dyspnea, chest tightness and shortness of breath, and heart failure may also occur. Patients who are not treated in time have a poor healing process. After the diagnosis is clear, attention should be paid to isolation and prevention of infection. Antiviral drugs should be applied promptly in severe cases.
SARS-CoV-2 & Flu & RSV Antigen Combo Rapid Test Kit (LFIA) is an immunochromatography based one step in vitro test. It is designed for the rapid qualitative determination of SARS-CoV-2, Inflfluenza A , Inflfluenza B and RSV virus antigen in swab samples from individuals suspected of COVID-19, Inflfluenza A , Inflfluenza B and RSV within the fifirst seven days of symptom onset. SARS-CoV-2 & Inflfluenza A/B Antigen Combo Rapid Test Kit (LFIA) shall not be used as sole basis to diagnose or exclude SARS-CoV-2, Inflfluenza A , Inflfluenza B and RSV infection.
SARS-CoV-2 & Flu & RSV Antigen Combo Rapid Test Kit (LFIA) uses a double antibody sandwich method to detect SARS-CoV-2 Inflfluenza A, Inflfluenza B and RSV by colloidal gold immunochromatography. When the appropriate amount of test samples treated with lysis buffffer is added to the sample well of the test cassette, the sample will move forward along the test strip by capillary action. If the sample contains SARS-CoV-2 , Inflfluenza A/B and RSV virus antigen, and the concentration is higher than the limit of detection, the antigen will form immune complexes with corresponding antibody labeled with colloidal gold respectively, which are captured by lines N line, A line, B line and R line. If test sample contains SARS-CoV-2 virus antigens, forming a red N line, indicating a positive result for SARS-CoV-2. If test sample contains Inflfluenza A virus antigens, forming a red A line, indicating a positive result for Inflfluenza A. If test sample contains Inflfluenza B virus antigens, forming a red B line, indicating a positive result for Inflfluenza B. If test sample contains RSV virus antigen, forming a red R line, indicating a positive result for RSV virus antigen.
Additionally, the test strip also contains a control line (C line). The C line should be formed to indicate that the sample has been transported properly through the membrane regardless of whether sample contains antigens or not. If the C line does not appear, it indicates that the test result is invalid and the sample need to retest.
Mutation Virus Detection Compatibility Tips
SARS-CoV-2 & Flu & RSV Antigen Combo Rapid Test Kit (LFIA) detects Nucleocapsid protein, NOT spike protein of SARS-CoV-2. And all of the following variants can be efectively detected by SARS-CoV-2 & Flu & RSV Antigen Combo Rapid Test Kit (LFIA).
