Positive Result

If both the quality control line C and the test line T appears, then it indicates a positive result for the neutralizing antibody to SARS-CoV-2 in the specimen.

Negative Result

If only the control line C appears and test line T does not appear, indicating a negative result for neutralizing antibody to SARS-CoV-2 in the specimen.

※   The intensity of the color showed on the T region varies depending on the concentration of neutralizing antibody to SARS-CoV-2   in the specimen.   Therefore, any shade of color on the T region should be considered positive.
