Lepu Covid-19 Neutralization IF Antibody Test

FLUORESCENCE IMMUNOCHROMATOGRAPHY

For Vaccine Effect Evaluation

Intended Use:

This product is used for qualitative detection of neutralizing antibodies to 2019-nCoV in clinical samples (serum/plasma/ whole blood).

Principle:

The test kit contains fluorescently-labeled 2019-nCoV Spike Protein (RBD), ACE2 Protein immobilized in test area (T) and the corresponding antibody in quality control area (C).

Operation Steps

Step 1 Add two drops (about 20 µl) of whole blood sample/ one drop (about 10µl) of serum or plasma sample to well A.
Step 2 Add three drops (about 100 µl) of sample dilution to well B, and start timing.
Step 3 Wait for 15 minutes, insert sample into catridge of immunoassay analyzer to read the results.

Applicable Instrument: LEPU Fluo-800

Result Interpretation

Reference Range: Inhibition rate≥20%

Positive : Inhibition rate≥20%, the sample contains 2019-nCoV neutralizing antibodies.
Negative : Inhibition rate＜20%, the sample does not contain the 2019-nCoV neutralizing antibodies or its content is below the limit of detection.
Invalid : No fluorescent signal is detected.
