How To Use Our COVID-19 Antibody Test Kit - Rapid Connect Medical

For you to perform diagnostic testing for COVID-19 antibodies, you will need quality and highly efficient Covid-19 antibody test kits. We recommend opting for our FDA EUA approved antibody testing kit. You can get your kits from Rapid Connect Medical if you are within the USA, Canada, South American, and European territories.

Reliable coronavirus antibody test kits contain six components inside:

  • Lancet
  • Alcohol Swab
  • Blood Pipette
  • Sample Diluent
  • Silver Sterile Packet
  • Antibody Detection Test Cassette

The above components are featured below in the various steps of using the rapid COVID-19 antibody test kit. Here are the steps you need to follow when using Rapid Connect Medical’s test kits:

Step 1: Lancet and Alcohol Swab

This is the blood collection stage of the testing. Here you are required to apply a warm compress on the fingertip before disinfecting with the alcohol wipe. After cleaning the patient’s fingertip with the alcohol swab, you then proceed to puncture it using the lancet. 

Hold the lancet against the patient’s fingertip and press down gently so that the sterile needle penetrates the skin to draw out blood. The needle is concealed before and after use to help minimize infection risk is by retracting back immediately inside the safety mechanism when blood starts to come out. The lancet can only be used once, so it should be properly disposed of after use. 

Step 2: Pipette or Mini Plastic Dropper

The next step will be extracting the blood from the punctured fingertip. Here you are required to use the provide pipette. Slightly depress the bulb to fill the tip of the instrument with blood. The whole blood collected by fingertip should be tested immediately after collection.

For short term storage, the serum and plasma specimens may be stored for up to 3 days at 35.5 – 46.4 °F (2-8℃), on the other hand, you will need a temperature of -4°F (-20℃) to store them for a much longer time.  Ensure that you do not freeze the specimens.

Step 3: Test Cassette

The test kit comes with a test cassette which is found in a sealed foil pouch. Remove the device and prepare it for the next step. This device should be used as soon as possible, within an hour, to get the best results.

Step 4: Test Cassette, Pipette or Mini Plastic Dropper and Buffer Solution

Lay the test cassette on a clean and flat or level surface and then add the specimen onto it. While holding the mini plastic dropper or pipette vertically, transfer a drop of the whole blood (about 10 μL) to the sample well labeled “S” on the test cassette. 

Immediately add two drops (about 80 μL) of the buffer sample to the buffer well labeled “B” on the test cassette ensuring that the vial tip does not touch the sample and that there are no air bubbles. 

Step 5: Test Cassette, Pipette or Mini Plastic Dropper and Buffer Solution

In this step, the control line “C” on the test cassette is expected to change from its blue color to red after two to minutes. In the case the blood is still present in the sample well “S” or the sample has not moved across the test window, then you’ll need to add one more drop of the buffer solution to the buffer well “B”.

 Step 6: Waiting Period

In this stage, you should expect to read the results after two to ten minutes. The results are only valid within 15 minutes. 

Step 7: Interpretation of Test Results

After reading the results, you will be required to interpret what you see on the test window. The test cassette forms three lines: C, G, and M. 

  • Positive:

The result is positive for IgM when the control line C and test line M both turn red. Also, the results are positive for IgG when the control line C and test line G turn red. The presence of both IgM and IgG only occurs when the control lines and the two test lines are visible on the test window (Red lines on C, G, and M lines). It is important to know that even a weak, light or faint line bands are considered as positive results. 

  • Negative:

The result of a diagnostic test for COVID-19 antibodies is negative when only the control line C changes color from blue to red. 

  • Invalid:

The results of a coronavirus antibody testing kit can be invalid, and this event usually occurs when only the control line (C) retains its blue color or when it is blue and any or both of the test lines appear on the test window. In this case, additional testing is required.

Interpreting your antibody test results - Rapid Connect Medical

Before testing, the rapid COVID-19 antibody test kit and the sample should be kept at room temperature or refrigerated (36-86⁰F or 2-30⁰C), but do not freeze it. The test cassette should be used before the expiration date printed on the sealed pouch and it must remain in the sealed pouch until when it is required for use. For the best results, the testing should be performed at room temperature (59-86°F or 15- 30℃).
