What You Need to Know About COVID 19 Antibody Tests - Rapid Connect Medical

In the medical world, antibody or serology tests are designed to detect past infections by looking for the presence of antibodies.  The presence of antibodies shows that your body has been fighting a particular disease. Since antibodies are disease-specific, in this article we are going to discuss proteins that are developed by the human immune system to fight COVID-19 and clear the virus. 

The human body produces antibodies one to three weeks after an infection, so an antibody test would not be appropriate to diagnose a current COVID-19 infection, you will need a viral test (PCR test). Diagnostic tests for COVID-19 antibodies are available in health centers and laboratories. You can test positive or negative for COVID-19 on an antibody test. 

Positive results from a COVID-19 antibody test shows that the patient has antibodies against coronavirus. The type of antibody detected, immunoglobulin G (IgG) or immunoglobulin M (IgM), will determine if it is a past or current infection. Individuals with asymptomatic infection may test positive for antibodies even though they don’t show symptoms of COVID-19.

Negative results from a COVID-19 antibody test is not a guarantee that you do not have the disease.  Some people take longer to develop antibodies. These findings can also be interpreted as a current infection, so the test may have to be repeated in one to three weeks to confirm the results. Individuals that develop symptoms after an antibody test must undergo a viral test. 

COVID-19 antibody tests are important in instances where the viral testing is delayed. Suspected individuals that may have been identified through contact tracing may be subjected to this testing technique. People coming from regions labeled as hotspots for coronavirus may be subjected to a serology test to obtain the history of the infection. 

A COVID-19 antibody test determines whether you had the disease in the past.  It also indicates that the patient has immunity against the disease. However, the level of immunity and how long it lasts may not be easy to determine from the results of an antibody test. There are ongoing studies to determine whether the presence of antibodies for COVID-19 means the person is protected against reinfection.  At this time it is indeterminate of how long antibodies stay in the human body.

For you to conduct a COVID-19 antibody test you will need a rapid COVID-19 antibody test kit and a blood sample, usually drawn from a finger prick. The sample for a finger-prick test can be whole blood, serum, or plasma. The plasma from a positive patient can be used as a convalescent plasma in developing a treatment for those who are critically ill.

In most situations, this type of testing is done when the patient has fully recovered from COVID-19.  The test may be administered to persons that may have had close contact with a patient who may have tested positive for Coronavirus infection. Testing negative for COVID-19 while showing symptoms similar to that of the disease calls for an antibody test to validate the results.

Access to the antibody test depends on your eligibility and availability of the test. Rapid Connect Medical ensures that the coronavirus antibody testing kit is available and can be purchased at an affordable price in large quantities. When more test kits are available it is easier for a nation to do mass testing. The data will help a country or organization develop informed strategies to curb COVID-19 pandemic.

The accuracy of an antibody test result relies on:

  • The sample collection 
  • The design of the Covid-19 Antibody Test Kit
  • The handling of the specimen and test kit
  • The reading and interpretation of results 
  • Sensitivity and specificity 

To determine the sensitivity and specificity of a rapid COVID-19 antibody test kit, you will need a performance validation. The more specimen used in the comparison study, the lower the confidence interval. Achieving true negative and true positive rates will help a lot in identifying and isolating the infected ones in a population to curb the spread of the virus.

Organizations will need reliable coronavirus antibody test kits to avoid the situation where the testing produces false-negative or false-positive results. What worries most of the doctors is when a test produces a false negative result.  Someone who has been declared negative while indeed he or she is positive for COVID-19 will further spread the disease unknowingly. 

Currently, the test kits used for COVID 19 antibody tests are designed for use by healthcare professionals. These tests help doctors to better understand how coronavirus is spreading within a community.  The kits are designed to test for specific antibodies, the ones supplied by Rapid Connect Medical will detect either IgM, IgG, or both.

A single finger prick to draw blood can be used with our kit that detects antibodies.  This positive or negative result can be detected as soon as 3 days after exposure to COVID-19 (sometimes before the onset of symptoms occur).

Knowing if you have active igM antibodies even in the first week of infection can help get the best treatment for an infected person.  If you do test positive, potentially exposed, or have traveled to a region with high infection rates, you should seek care from your doctor for treatment and continue to test for IgG antibodies daily until you are cleared to leave quarantine.

The kits used for diagnostic tests for COVID-19 antibodies are usually designed for research use or qualitative detection of coronavirus, and not home use. Also, they can only be used to test the presence of IgG and IgM antibodies against SARS-CoV-2. Since they are aiding tools to RT-PCR or CT scanning, a clinical diagnosis of COVID-19 should be done by a healthcare professional or physician.

An antibody detection test cassette contains antigens from SARS-CoV-2 combined with gold nanoparticles. The device has two wells (one for specimen and one buffer) and a control region on the upper end.  Two types of antibodies are of great importance in diagnostic tests for COVID-19 antibodies: Immunoglobulin M (IgM) and Immunoglobulin G (IgG). 

The importance of the gold nanoparticles in the detection test cassette is to create a colored line in the control region.  Antigens targeting a specific antibody are located in their respective regions on the nitrocellulose membrane of the test cassette. The IgG and IgM regions are coated with anti-human antibodies for each.
