COVID-19 Neutralizing Antibody Rapid Test Kit(Whole Blood/Serum/Plasma) is a lateral flow immunoassay intended for qualitative detection of Neutralizing Antibody in whole blood/serum/plasma specimens from individuals suspected of COVID-19 who have recovered from infection or vaccined. Results are for the identification of COVID-19 Neutralizing Antibody. Antibody is generally detectable in whole blood/serum/plasma during the acute phase of recovery or after vaccined. Positive results indicate the presence of Neutralizing Antibody.
COVID-19 Neutralizing Antibody Rapid Test Kit(Whole Blood/Serum/Plasma) is intended for use by medical professionals or trained operators who are proficient in performing rapid lateralflow tests.
【TEST KIT COMPOSITION】
Consider any materials of human origin as infectious and handle them using standard biosafety procedures.
Collect venous blood specimen into a lavender, blue or green top collection tube (containing EDTA, citrate or heparin, respectively in Vacutainer) by veinpuncture.
Collect venous blood specimen into a lavender, blue or green top collection tube (containing EDTA, citrate or heparin, respectively in Vacutainer) by veinpuncture. Separate the plasma by centrifuge. Carefully withdraw the plasma into new pre-labeled tube.
Collect venous blood specimen into a red top collection tube (containing no anticoagulants in Vacutainer) by veinpuncture. Allow the blood to clot. Separate the serum by centrifuge. Carefully withdraw the serum into a new pre-labeled tube.
Wash hands with soap, disinfect the finger tip with alcohol pad, then dip the finger tip with lancet,collect blood specimen with the dropper.
Test specimens as soon as possible after collecting. Store specimens at 2°C-8°C if not tested immediately up to 5 days. The specimens should be frozen at-20°C for longer storage except whole blood specimen.
Avoid multiple freeze-thaw cycles. Prior to testing, bring frozen specimens to room temperature slowly and mix
gently. Specimens containing visible particulate matter should be clarified by centrifuge before testing. Do not use samples demonstrating gross lipemia, gross hemolysis or turbidity in order to avoid interference on result interpretation.
[INTERPRETATION OF THE RESULT]
Bring the specimen and test components to room temperature. Mix the specimen well prior to assay once thawed. Place the test device on a clean, flat surface.
Fill the dropper with the specimen then vertically add 2 drops(about 25 µL ) of specimen into the sample well. Then add 1 drop (about 30 µL) of sample solution immediately into the sample well. Making sure that there are no air bubbles.
Set up a timer. Read the result at 10 minutes.
