CHECK TEST
Covid-19 RBD test

Description
Rapid immunochromatographic assay for the qualitative detection of IgG antibodies of the binding domain for the SARS-CoV-2 spike (S) receptor protein (RBD) in human fingerstick whole blood approximately 10 days post vaccination. It is designed to assist in the identification of individuals with an adaptive immunological response to SARSCoV-2. The results are for the detection of S-RBDSARSCoV-2 IgG antibodies. Positive results indicate the presence of IgG antibodies to SARSCoV-2.

How to use
Before the test:
Bring the test and buffer to room temperature (15-30 ° C) before use.
Wash your hands well with warm water and dry them.
Remove the test cassette from the sealed pouch and use it within 1 hour.
Do not touch the test reaction zone (the strip next to the letters C, T, S) of the test strip. Best results are obtained if the test is performed immediately after opening. Place the test on a flat, clean surface.
1. Use the alcohol swab to clean the tip of the middle or ring finger to puncture. Leave to dry for 10 seconds.
2. Gently twist and remove the lancet cap. Open the lancet only just before testing.
3. Press the sterile lancet firmly against the tip of the middle or ring finger.
4. To increase blood flow, use your thumb and index finger to apply gentle pressure around the puncture site.
5. Without squeezing the dropper, put it in contact with the blood. The blood must reach the line indicated on the dropper. You can massage your finger again to get more blood if the line is not reached. Avoid air bubbles, discard the blood in a plastic bag (e.g., biosecurity bag) if air bubbles occur, then repeat the previous collection steps.
6. Place the tip of the dropper in contact with the center of the sample well (S) and release all blood immediately after collection.
7. Add 2 drops of buffer to the sample well (S) and start the timer. Do not move the test during development.
8. Read the results at 10 minutes. Do not interpret the results after 20 minutes.
Positive: * two colored lines appear. One colored line in the control region (C) and another in the test region (T). A positive result in the test area indicates the detection of IgG S-RBD SARSCoV-2 in the specimen.
* Note: The intensity of the color in the test line (T) varies depending on the amount of IgG S-RBD SARS-CoV-2 present in the sample. Therefore any color hues in the test area (T) must be considered positive.
Negative: A colored line appears in the control region (C). There is no colored line in the test area (T). A negative result indicates that the S-RBD SARS-CoV-2 IgG antibody was not detected in the sample.
Null: the Control line does not appear. Insufficient sample volume or incorrect procedural techniques are the most common reasons for control line failure. Review the procedure and repeat the test with a new device. If the problem persists stop using the test immediately and contact the supplier.
