August Update: What You Need to Know About Covid-19 Antibody Tests

COVID-19 antibody tests play a significant role in the Diagnosis of coronavirus disease 2019 (COVID-19). Although they may not detect the disease-causing virus, SARS-CoV-2, they can detect the presence of coronavirus antibodies in the blood. Simply put, COVID-19 antibody tests provide information about the patient’s immune response to the viral infection.

Presence of Antibodies

The reason why antibody tests are not used as the only basis to diagnose COVID-19 is that the antibodies to the novel coronavirus may not be present during the early stage of the infection. The antibodies produced by the human body are disease-specific, therefore antibody tests must be accurate in such a way that there are no cases of cross-sensitivity or cross-reactivity.

Studies have also shown that the levels of antibodies in the blood drop dramatically about a few months after infection.  For this reason, timing has become a vital factor of consideration when performing diagnostic tests for COVID-19 antibodies. Early or late testing can produce false-negative results because the antibodies are cannot be detected or they have decayed, respectively. 

Quantity of Antibodies

As of July 31, 2020, it is now possible to estimate the number of antibodies present in an individual’s blood using a COVID-19 antibody test kit. On this date, the FDA authorized the first tests that can display an estimated quantity of a patient’s antibodies from past sars-CoV-2 Infection. These semi-quantitative tests will help a lot in further understanding the role of the antibodies in fighting coronavirus.

Future Protection and treatment

Many Nations are seeing the COVID-19 antibody tests as a game-changer to reopening the economy. Any reliable information showing that the presence of antibodies in the blood offers protection against future infections will put the world back to business as usual. According to scientists, the immunity against SARS-CoV-2 may not be long-lasting in patients that have registered mild illness.

Scientists are relying on the behavior of the sars-CoV-2 to determine how long the COVID-19 antibodies will last in the body.  Currently, there are different strains of coronavirus and no one knows whether it will evolve or mutate to a different strain.

What we know so far is that the human immunity against the novel coronavirus is short-lived. This creates concern about the issuance of antibody-based “immunity passports” and the overreliance on herd immunity in many countries to open up their economies.

Besides future protection, other scientists have a keen interest in the “convalescent plasma” of patients that have tested positive for sars-CoV-2 antibodies. The scientists are trying to use this part of the blood to develop a possible treatment that can be of help to individuals that are critically ill from COVID-19.

Accuracy of Covid-19 Antibody Tests

With the mad rush to make huge numbers of rapid COVID-19 antibody test kits, it is not even clear if these devices are accurate enough to guide in decision making. Validation studies done on several Chinese-made coronavirus antibody testing kits have shown varying performance data with some recording very low accuracy rates.

World Health Organization and FDA have cautioned countries and organizations from using COVID-19 antibody tests as tickets back to school or work. The presence of faulty test kits in the market hinders the efforts governments and public health agencies have put in place to curb the spread of SARS-CoV-2.

Are COVID-19 antibody tests reliable? The chances of getting false positive and false negative results using antibody tests are high compared to molecular tests. Diagnostic tests for COVID-19 antibodies might mistake other coronavirus antibodies for the SARS-CoV-2 antibody. Also, they can pronounce someone as COVID-19 free, while in reality, the person has undetectable amounts of antibodies in the blood. 

Therefore, not all test kits can truly detect the presence of COVID-19 antibodies. The FDA has also confirmed the presence of flawed results from most of the commercial test kits the agency has tested so far. The best testing results using a rapid COVID-19 antibody test kit are confirmed by molecular tests viral RNA tests, (PCR tests or nucleic acid tests).

At the moment, Covid-19 antibody tests are useful to scientists and medical professionals in understanding the prevalence of individuals with antibodies for SARS-CoV-2 in a target population. According to the CDC, antibody tests can only be used to diagnose a current COVID-19 infection, only when viral testing is delayed. This is possible because an ongoing infection can be detected by the presence of IgM antibodies one to three weeks after infection.

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.
