Rapid test for the qualitative detection of SARS-CoV-2 antigens in human nasopharyngeal specimens. For professional in-vitro diagnostic use only
In December 2019 cases of pneumonia of unknown etiology were reported in Wuhan, Hubei Province, China. In January 2020, the Chinese Center for Disease Control and Prevention (CDC) identified Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) as the causative agent of this first outbreak and the related disease was defined as Coronavirus Disease 2019 (COVID-19).
As well as other respiratory diseases, SARS-CoV-2 can cause an asymptomatic infection, mild symptoms such as cold, sore throat, cough and fever, loss of taste and/or sense of smell, or more severe symptoms such as pneumonia and respiratory distress with a fatal outcome. The incubation period of SARS-CoV-2 varies from 1 to 14 days, with an average of 3 to 7 days.
The CDC, the US Center for Disease Control and Prevention, recommends that samples taken from the upper respiratory tract, such as nasopharyngeal ones, have to be collected and tested in order to identify the presence of genetic material or antigens of the pathogen. In particular, antigenic tests detect the presence of proteins that are structural and functional components of the pathogen itself and are very specific to the target microorganism.

WHO IS THIS TEST FOR?
PRIMACOVID® ANTIGEN RAPID TEST is intended for use by healthcare professionals as a first approach in the diagnosis of COVID-19, with the aim of supporting personnel in emergency management with timely responses, in just 10 minutes.
Antigenic tests for COVID-19 allow to carry out a qualitative detection of SARS-CoV-2 in the patient sample and are intended as rapid diagnostic devices to be carried out in the point of care. The incubation period for SARS-CoV-2 virus can range from 1 to 14 days, with an average of 3 to 7 days. It is therefore recommended to use this device during this timeframe starting from possible exposure to the virus.
PRIMACOVID® ANTIGEN RAPID TEST is a rapid lateral flow immunochromatographic device for the detection of SARS-CoV-2 antigens in human nasopharyngeal swab samples. During the test, any SARS-CoV-2 antigens present in the sample react with the anti-SARS-CoV-2 antibody coated nanoparticles present in the test strip. A positive result indicates that the antigen concentration is close to the Limit Of Detection (LOD) of 500 pg / mL.
rapid immunochromatographic lateral-flow assay
Results reading time
nasal and/or nasopharyngeal swab
20 test cassettes
20 vials with dropper containing the extraction buffer
20 nasopharyngeal swabs
instructions for use
Obtain the nasopharyngeal sample by inserting the swab in the nasal cavity and holding it parallel to the palate. Gently rub and roll it and take it out;
Insert the swab into the extraction buffer, rotate and remove it while squeezing the sides of the test tube in order to extract as much liquid as possible;
Apply 2 drops of the extracted specimen and wait 10 minutes before reading the result.
no SARS-CoV-2 antigens have been detected in the sample or their concentration is below the Limit of Detection (LOD) of 500 pg/mL.
SARS-CoV-2 antigens have been detected in the sample, thus a possible ongoing infection.

The test has been carried out correctly when the instructions for use are followed. It includes the reading time and the interpretation of the results shown at the "RESULTS INTERPRETATION" section of the instructions for use.
A colored line will appear at the control region (C) on the test device, showing that the test performed correctly. The absence of the colored line suggests to repeat the test with a new device and a new sample.
