StrongStep SARS-CoV-2 Antigen Rapid Test
Description
Rapid immunochromatographic assay for the detection of SARS-CoV-2 virus protein nucleocapsid antigen in nasal / nasopharyngeal / saliva swab collected from asymptomatic or symptomatic individuals suspected of being infected with COVID-19 within the first five days of onset of symptoms.
Latex-conjugated antibodies (Latex-Ab) corresponding to SARS-CoV-2 are dry immobilized at the end of the nitrocellulose membrane strip. SARS-CoV-2 antibodies are bound to the Test Zone (T) and biotin- BSA is connected to the control area (C).
When the sample is added, it migrates by capillary diffusion rehydrating the latex conjugate.
If present in the sample, SARS-CoV-2 antigens will bind to the conjugated antibodies to form particles. These particles will continue to migrate along the strip to the Test Zone (T) where they are captured by SARS-CoV-2 antibodies generating a visible red line.
If no SARS-CoV-2 antigens are present in the specimen, no red line will form in the Test Zone (T).
The streptavidin conjugate will continue to migrate on its own until it is captured in the Control Zone (C) by biotin-BSA which aggregates in a blue line, indicating the validity of the test.
The test is used as an aid in diagnosing COVID-19. It is designed to be used for infection screening and auxiliary diagnosis in symptomatic and asymptomatic people.
How to use
Collection and storage of samples
1. Nasal Swab Sample: Insert a swab into a patient's nostril. The tip of the swab should be inserted up to 2.5 cm (1 inch) from the edge of the nostril. Rotate the swab 5 times along the mucosa inside the nostril to ensure that both mucus and cells are collected. Using the same swab, repeat this process for the other nostril to ensure that an adequate sample is collected from both nasal passages.
2. Nasopharyngeal Swab Sample: Insert a swab into the patient's nose, parallel to the nasal floor and septum. Continue inserting the swab until resistance is felt, indicating contact with the nasopharynx. Once the patient's nasopharynx is reached, it is recommended that the swab be rotated gently, allowing it to complete two full rotations, to allow for absorption of secretions into the nasopharynx. Perform the same procedure in the other nostril as well.
3. Saliva sample: Remove the seal from the tube containing the extraction liquid. Install the saliva collection funnel on the tube and spit the saliva into the tube through the funnel. Once finished, remove the funnel from the tube.
It is recommended that specimens be processed as soon as possible after collection.
Samples can be stored in containers for up to 1 hour at room temperature (15 ° C to 30 ° C) or up to 24 hours if refrigerated (2 ° C to 8 ° C) prior to processing.
Procedure
Bring test devices, specimens, buffer and / or controls to room temperature (15-30 ° C) before use.
Remove the seal from the tube containing the extraction liquid. Insert the sample into the tube and mix the solution vigorously by twisting the swab firmly against the side of the tube at least ten times (while immersed). Best results are obtained when the sample is mixed vigorously into the solution.
Leave the swab immersed in the extraction solution for one minute before the next step. Press the walls of the tube with your fingers to release as much sample as possible into the extraction solution. Break off the tea rod
