COVID-19 (SARS-CoV-2) Neutralizing Antibody Test
Inspection Principle
The lateral flow assay and the principle of competition were used to detect the neutralizing antibodies against SARS-CoV-2 in human serum or plasma specimens.

Main Ingredients
Anti-SARS-COV-2 Neutralizing Antibody Test cassette
Specimen Dilution Buffer
Pipette
Desiccant
Storage and Stability
Store at 2℃~ 30℃ in a dry place and avoid direct sunlight. Do not freeze. It is valid for 18 months from date of manufacturing.
After the aluminum foil bag is unsealed, the test card should be used as soon as possible within one hour.
Test Procedure
1. Please read the instruction manual carefully before testing.a
2. Take out the test cassette, specimen dilution buffer, etc., and use it after returning to room temperature. When everything is ready, tear off the aluminum foil bag, take out the test cassette and place it on the platform. 3. 3. After opening the aluminum foil bag, the test cassette should be used as soon as possible within 1 hour.
4. Aspirate the plasma / serum specimen with the pipette, add 1 drop (approximately 20ul) of specimen to the sample well of the test cassette, and then open the specimen dilution buffer drop bottle, add 2 drops (about 80ul) of specimen dilution buffer to the well.
5. Timing observation: judge the result 15 minutes after specimen adding, do not observe the result 20 minutes later.
Positive: Only the quality control line (C line) has a red line, and the test line (T line) has no red line. It indicate the presence of SARS-CoV-2 neutralizing antibodies above the detection limit of the test kit in the specimen.
Negative: The red lines appear on the quality control line (C line) and the test line (T line). It means that no SARS-CoV-2 neutralizing antibodies in the specimen or SARS-CoV-2 neutralizing antibodies level is below the detection level.
Invalid: No red line appears on the quality control line (C line), indicating failure. It may be due to improper operation or test cassette is invalid and should be retried.
