What We Know So Far About COVID-19 Antibody Tests - Rapid Connect Medical

COVID-19 antibody tests are not your normal diagnostic tests for coronavirus disease 2019 (COVID-19). A typical COVID-19 diagnostic test will be looking for the disease-causing virus scientifically known as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). These diagnostics tests target the virus’s genetic material, more so the spike protein.

While most scientists are looking for the major antigen responsible for the wide spread of the COVID-19, others are designing tests to help them identify antibodies to the nucleocapsid, or N, a protein bound up with the coronavirus genetic material. With COVID-19 antibody or serology tests, scientists and health professionals are mostly interested in the human body immune response to COVID-19.

The symptoms one develops from an infection with the coronavirus can be mild or severe. Another case that most nations are working hard to mitigate is the spread of COVID-19 through asymptomatic patients. Since the diagnostic test show that these individuals test negative for the disease, a COVID 19 antibody test will be required to confirm these findings.

The immune system is the best defense humans have against COVID-19.  This system produces antibodies to fight and get rid of antigens that are harmful to the body. Scientist have identified antibodies that block the novel coronaviruses from infecting the human body cells. Most COVID-19 antibody test kits are designed to identify two antibody subtypes: immunoglobulin M (IgM) and immunoglobulin G (IgG).

Nowadays, many people are turning to COVID 19 antibody tests to determine whether they have been exposed to SARS-CoV-2.  In some cases, these tests may fail to detect the presence of antibodies and yield negative results during the first few days after the onset of Coronavirus disease symptoms and during the recovery period.

In the early stage of the infection, the body tends to produce small amounts of undetectable antibodies hence the negative results. After recovering from the disease, research has shown that the volume of coronavirus antibodies in patients tends to drop drastically with time and this explains why some people who might have tested positive for COVID-19 end up testing negative in antibody tests. 

Recent studies have shown that the neutralizing antibodies against coronaviruses often wane a few weeks after the patient has fully recovered from COVID-19. Some studies have revealed that the levels of antibodies against SARS-CoV-2 begin to fall about a month after the appearance of symptoms for the disease. The antibodies become few in number to the point where they can’t be detected.

COVID 19 antibody or serology tests are done when a COVID-19 patient has full recovered from the disease.  One is eligible for the test if:

  • You have had contact with a person that may have tested positive for the disease
  • You are coming from an area that is considered a hotbed of COVID-19
  • You have tested positive for COVID-19 but have not developed any symptoms of the disease

You may need to consult your doctor or any qualified health care professional before taking a COVID-19 antibody test. Getting access to these tests will depend on where you live and the availability of diagnostic tests for COVID-19 antibodies.

Individuals diagnosed with coronavirus disease that have developed antibodies are eligible to donate a portion of their blood plasma. The convalescent plasma sample is then used by scientists to develop treatment for those who are seriously ill or vulnerable to COVID-19.

According to World Health Organization, there is limited or lack of evidence that the presence of COVID-19 antibodies is a guarantee that the individual is protected against reinfection. It is hard to tell the level of immunity one has from diagnostic tests for COVID-19 antibodies. Most scientist are counting on the anamnestic response of antibodies to prevent patients who have recovered from COVID from re-infection.

The accuracy of COVID 19 antibody tests rely on a couple of factors, some of them include:

  • Timing for COVID-19 antibody tests
  • Type and performance of the coronavirus antibody testing kit
  • Blood sample collections
  • Skill and expertise of the administrator
  • Use of the rapid COVID-19 antibody test kit

The accuracy of a COVID-19 antibody test is determined by its sensitivity (true positive rate) and specificity (true negative rate).

From what we know about COVID-19 antibody tests, it is important that you or your organization get the best results.

The sampling done with the rapid COVID-19 antibody test kit cassette using lateral flow from Rapid Connect Medical will give you the IgG and IgM detectable diagnostics results from between two and ten minutes. It can be used for reference in combination with the results from an RT-PCR (reverse transcriptase-polymerase chain reaction) test. 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 sensitivity, specificity, and accuracy or our antibody test kit is very high.  This testing method for the public gives real time results and helps to identify initial infection before the severe flu like symptoms begin.  This kit is intended to be administered by a health care professionals and providers at a clinic or other health care facilities.  Many of the faulty test kits were removed from the FDA EUA website; all of our test kits are authorized by the FDA and their data appears and is included on that website.  Consumers can trust the validity and quality of the antibody test kits sold by Rapid Connect Medical.

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. 

The rapid COVID-19 antibody test kits you will find on the market are designed to detect SARS-CoV-2-specific antibodies. The ones distributed by Rapid Connect Medical are FDA research approved and evaluated and validated by a comprehensive clinical study.  This antigen test kit was developed in response to the COVID-19 global pandemic and offers a power tool for health care providers.  The immune response produced by a Coronavirus viral infection is what this test measures.  The CDC testing standards for laboratories were strictly followed during the clinical trials for our antibody test kit.

This is a serology elisa based test for SARS-CoV-2 antibodies in serum or plasma components of blood. Information on the collection data, total sample size, and validation of lab samples can be found here for review.  Interpretations of test results should be confirmed with a lab and a a medical professional should diagnose your infection status not only on the sole basis of your rapid test kit results.  This rapidtest should be performed by a licensed medical professional and your infection status determination may require additional tests.  With the presence for IgG antibodies people can have immunity for some time.  While viruses such as influenza have been a problem in the past, Covid-19 is a serious problem we aim to help eliminate.
