COVID-19 Antibody Tests: What the Results Tell Us About COVID-19

COVID-19 Antibody Tests: What the Results Tell Us About COVID-19 - Rapid Connect Medical

COVID-19 antibody tests as the name suggests are examinations that are designed to detect antibodies produced by the human body to deal with the novel coronavirus. These have become crucial tools used by nations and organizations to do more testing and isolation with the aim of mitigate the spread of COVID-19, now that it has become a pandemic.

In this article we set out to learn from the results of COVID-19 antibody tests done all over the world and if possible, use the knowledge to intensify our mass testing strategies.  What we already know is that these assays have a useful role in detecting if someone has contracted the virus. This method of testing is more popular in European countries. 

COVID-19 virus infections in human bodies are detected when the individuals start developing symptoms specific to the disease. To confirm that you are indeed positive for coronavirus, you will need to take a COVID-19 diagnostic test. In the early stage of the infection, your physician may recommend a molecular assay, such as the PCR (Polymerase Chain Reaction) swab test.

Another way to inform researchers and scientist on the presence of the pathogen in the body is through antibody or serology tests. Most health professionals prefer antibody tests as complements of PCR or any other molecular testing method. What the scientist are yet to discovered is whether patients who have completely recovered from the disease are immune to future infection.

There are two types of COVID-19 antibody tests being used all around the world and these are point-of-care or lateral flow assays and ELISA (enzyme-linked immunosorbent assay) assays. Both of these methods will require a coronavirus antibody testing kit.  The ELISA is usually done in a laboratory setting, while the point-of-care as the name suggests it can be used outside the confines of a lab or health center.

During a COVID-19 antibody test, the presence of the IgM (immunoglobulin-M) indicates that the body is still fighting the virus. If only IgG (immunoglobulin-G) then you might have contacted COVID-19 and recovered from it.

The most advanced COVID-19 antibody tests are able to detect both IgM and IgG antibodies.  These studies tell us that the two types of antibodies are the most active immune response proteins produced to deal with the novel coronavirus.

COVID-19 antibody tests usually require samples from the patients that have fully recovered from the novel coronavirus disease.  These specimens are obtained from the individual’s blood and it can be in the form of whole blood, plasma or serum.  A coronavirus antibody testing kit usually comes with a lancet that is used to prick a patient’s finger to obtain a small amount of blood sample for testing.

According to results obtained from COVID-19 antibody tests, researcher and scientist have found only clues to how long the immune response lasts and the levels of antibodies produced to fight subsequent SARS-CoV-2 infections. The type and level of antibodies match the type of infection, mild symptoms yield less antibodies. 

COVID-19 antibody tests performed at different times since symptom onset show that the accuracy of the assays depend on timing. These tests were better at the presence of coronavirus antibodies two or more weeks after the onset of specific COVID-19 symptoms. Recent studies reveal that the chances of detecting antibodies a month after the symptoms have started is quite minimal since they wane slowly with time.

Going by the FDA EUA validation process for COVID-19 antibody tests, it is evident that the accuracy of the assay relies on the type of kit used. Some test kits may fail to detect antibodies against Coronavirus in patients that are diagnosed for COVID-19 (sensitivity), while others may declare one positive when the person has no symptoms and shows no sign of the virus using molecular tests (specificity).

In a population where patients have been diagnosed with coronavirus disease, most COVID-19 antibody tests are likely to yield more false negatives. On the other hand, diagnostic tests for coronavirus disease antibodies on people that are confirmed negative for coronavirus you should expect results that have more false positives and less false negatives.

We learn that all diagnostic tests for coronavirus antibodies are not 100% accurate, there are some tests that yield false-negative and false positive-results. The timing of COVID-19 antibody tests is the number one factor that can prevent you from getting accurate results when using this method of testing. There is also a need to evaluate the performance of commercial antibody tests in the market.

For accurate results you’ll need reliable coronavirus antibody test kits and well-trained administrators. You can get a coronavirus (SARS-CoV-2) IgM/IgG rapid test kit that is FDA Emergency Use Authorization (EUA) approved and CE certified from Rapid Connect Medical. You can place a bulk order from Rapid Connect Medical if you have a large organization.

Rapid Connect Medical is an exclusive distributor of the FDA EUA authorized rapid COVID-19 antibody test kit.

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.

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.
