Test principle
This product uses double antigen sandwich method for detection. The gold label pad is marked with S-RBD-mFcC-terminal, and the detection line is coated with S-RBD-mFc N-terminal. When the sample contains neutralizing antibody, it will bind to S-RBD-mFc C-terminal, then the complex will be captured by pre-coated S-RBD-mFc N-terminal and the T line will show color. When the sample does not contain neutralizing antibodies, the T line will not show color. The quality control line is coated with goat anti-mouse polyclonal antibody. The C line will show color regardless of whether the sample contains neutralizing antibody.

Test Procedure
Allow test device extraction reagent and specimens to equilibrate to room temperature(15 ~ 30 ℃） prior to testing.Please keep the temperature at 15 ~ 30 ℃ and the humidity at 20%-80% during the whole test.
1.Specimen Collection
（1）Wipe the fingertips with an Alcohol Swab
（2）Pull out the cap on the front end of the lancet. Use sterile lancet to gently press on the wiped area
（3）Squeeze out a sufficient amount of blood
（4）Pinch the bulb at the upper end of the disposable sampler, place the lower end vertically in the blood, and then slowly loosen the bulb. The blood must exceed the thin tube, as shown in the figure as an example.
2.Testing
（1）Add a drop of blood to the sample well(S).
（2）Break off the bottleneck of the buffer solution and squeeze a drop of buffer solution into the sample hole. Start the timer.
3.Test Results
Read result at 15 minutes.Do not read results after 30minutes.
