Product Introduction

The Anti-SARS-CoV-2 Neutralization Antibody Test Kit (Serum/Plasma/Whole blood) is a qualitative membrane-based immunoassay for the detection of SARS-CoV-2 neutralizing antibodies in serum, plasma and whole blood. The sample is dropped into the sample well, and chromatography is performed under the capillary effect. The SARS-CoV-2 neutralizing antibodies in the sample combined with the colloidal gold-labeled SARS-CoV-2 spike protein(SP), then spread to the test area. It is captured by coated SP subunit RBDNTD-CTD, to form a complex and gather in the test area (T line). The quality control area is coated with mouse anti-chicken IgY, and the colloidal goldlabeled chicken IgY is captureed to form a complex and aggregate in hte quality control area (C line). If the C line does not show color, it indicates that the result is invalid, and this sample need to be tested again.

Product Features

Sensitivity is 98.198% (95%CI: 93.643%, 99.781%) and specificity is 98.252% (95%CI: 96.709%, 99.198%).

Procedure is simple and time saving.

All necessary reagents provided & no equipment needed.

Obtain CE certification.

Suitable for large scale rapid screening.

Test Procedure

Bring the pouch to room temperature before opening. Take the cassette from the sealed pouch and use it within ONE hour.

Place the cassette on a clean and flat surface.

For Serum or Plasma samples: add 1 drop (approximately 30 μL) of sample into sample well, then add 4 drops of buffer and start the timer. Avoid trapping air bubbles into the sample well.

For Whole Blood samples: add 2 drops (approximately 50 μL) of whole blood sample into sample well, then add 4 drops of buffer as soon as possible and start the timer. Avoid trapping air bubbles into the sample well. Note: It’s recommended to add 1 more drop of buffer if the liquid flows too slowly.

Wait for the colored line(s) to appear. The result shall be read at 15 minutes. The result is valid within 30 minutes.

Testing Results

Positive: Both the test line (T line) and the quality control line (C line) appear colors.

Negative: The test line (T line) does not appear color, only the quality control line (C line) appears color.

Invalid: The quality control line (C line) does not appear color, which means that the test is invalid and the test should be repeated.
