The NADAL® COVID-19 Ag Test is a lateral flow chromatographic immunoassay for the qualitative detection of SARSCoV-2 viral nucleoprotein antigens in human nasal, nasopharyngeal or oropharyngeal specimens. This test is intended for use as an aid in the diagnosis of infections with SARS-CoV-2. Note that the concentration of viral nucleoprotein antigens may vary in the course of the disease and might fall below the detection limit of the test. Possible infectiousness of test subjects cannot be ruled out based on negative test results. The test procedure is not automated and requires no special training or qualification. The NADAL® COVID-19 Ag Test is designed for professional use only.
COVID-19 (Corona Virus Disease) is the infectious disease caused by the recently discovered coronavirus SARS-CoV-2. The most common symptoms of COVID-19 are fever, dry cough, fatigue, sputum production, shortness of breath, sore throat and headache. Some patients may have myalgia, chills, nausea, nasal congestion and diarrhoea. These symptoms begin gradually and are mild in most of the cases. Some people become infected but do not develop any symptoms and do not feel unwell. Most people (about 80%) recover from the disease without special treatment. Approximately one in six people who get infected with COVID-19 becomes seriously ill and develops difficulty breathing. Elderly people, and those with pre-existing conditions, such as high blood pressure, heart problems or diabetes, are more likely to develop serious illness. So far, about 2% of infected people have died. COVID-19 is transmitted via respiratory droplets that are exhaled by infected people via coughing, sneezing or talking. These droplets can be inhaled or ingested directly by other people or can contaminate surfaces, which can then be infectious for several days. Most estimates of the incubation period for COVID-19 range from 1 to 14 days, during which people might already be infectious without showing disease symptoms.
