The EcoTest COVID-19 IgG/IgM Rapid Test Device is an in-vitro immunoassay for the direct and qualitative detection of anti-SARS-CoV-2 IgM and anti-SARS-CoV-2 IgG in human whole blood, serum or plasma.

EcoTest has been validated by the FDA and found to have a 100% Sensitivity for IgM (30/30) and 98.8% Specificity for IgM (79/80). IgG Sensitivity was 90% (27/30) and Specificity was 100% (80/80).

EcoTest is one of only a small number of COVID-19 rapid antibody tests that have both FDA Emergency Use Authorization and that detect two types of antibodies (IgM and IgG) - IgM peaks early in the disease and IgG peaks later during the illness. This combination provides broader capture of patients exposed to COVID-19. EcoTest performance was validated by a US physician researcher and several of the box contents were enhanced as a result. There is no other COVID Rapid Antibody test like it on the market. EcoTest is for professional use only.

How it Works

EcoTest is a serology test. Serology tests use a patient's blood, serum, or plasma to identify the presence of IgM and IgG antibodies. Unlike PCR based testing, Serology testing provides rapid results in 15 minutes.

EcoTest is designed to detect antibodies (immunoglobulins, IgG and IgM) against the coronavirus (SARS-CoV-2). Antibodies are proteins produced by the immune system in response to a specific infection. They are found in the serum or plasma and develop approximately one week after an individual has been infected.

Antibody Test for IgG

This test detects IgG antibodies that develop in most patients within seven to 10 days after symptoms of COVID-19 begin. IgG antibodies remain in the blood after an infection has passed. These antibodies indicate that you may have had COVID-19 in the recent past and have developed antibodies that may protect you from future infection. It is unknown at this point how much protection antibodies might provide against reinfection. IgG peaks at 14-21 days.

Antibody Test for IgM

This test detects IgM antibodies. IgM is usually the first antibody produced by the immune system when a virus attacks. A positive IgM test indicates that you may have been infected and that your immune system has started responding to the virus. When IgM is detected you may still be infected, or you may have recently recovered from a COVID-19 infection.

IgM antibodies are produced by someone with an active COVID-19 infection on average around 7 days after infection, but as early as 4 days.

On average these antibodies disappear after about 28 days


The test is for in vitro diagnostic use only.

The test results of this kit are for clinical reference only. The clinical diagnosis and treatment of patients should be considered in combination with their symptoms/signs, medical history, other laboratory tests, and treatment response.


Antibody tests cannot guarantee 100% accuracy as they are produced after a person has been infected. Because of this time window where acute inflections may be missed, clinicians should be advised to follow government guidelines for those exhibiting symptoms.

Negative results do not rule out SARS-CoV-2 infection, particularly in those who have been in contact with the virus. Follow-up testing with a molecular diagnostic should be considered to rule out infection in these individuals.

This kit is for Professional-Use-Only.

Differences between Antigen vs. Antibody COVID testing

The COVID-19 pandemic continues to impact our communities across the United States and many countries across the world. COVID testing remains our strongest response in order to manage and keep the spread of COVID under control. PCR tests remain the benchmark in COVID testing and are used to detect persons currently infected with the COVID-19 virus. However, there are several alternative tests available on the market today, including the antigen and antibody tests. Let’s take a look in order to learn the difference between the Antigen vs. Antibody COVID tests.

In order to learn what an antigen covid test can tell us, we must first learn what an antigen is. In immunology, an antigen is a molecule that can be found on the outside of a pathogen in our body. It’s a foreign substance that induces an immune response in our bodies and is bound by an antigen-specific antibody. When our body senses the presence of antigens, an immune response is normally triggered. All antigens have their own unique characteristics and features that our immune system recognizes.

What’s the difference between Antigens vs. Antibodies?

COVID-19 is caused by a coronavirus called SARS-CoV-2. SARS-CoV-2 carries antigens, including nucleocapsid protein that create spiky protrusions on the surface, a now universal image of the coronavirus.

Antibodies are produced by our body in response to the exposure of antigens, like those found in COVID-19. These antibodies are Y-shaped proteins that our immune system produces from B-cells in our body. Antibodies contain antigen-binding parts called paratopes. Paratopes bind to epitopes on the antigen’s surface. The binding between paratopes and epitopes helps our immune system to eliminate the antigens in the body.

When somebody is infected with the SARS-CoV-2 virus, their body produces these antibodies that bind to antigens to help eliminate the coronavirus. The binding result that is caused by antibodies and antigens in response to the COVID-19 virus is used to develop the antibody and antigen tests to detect the presence of SARS-CoV-2 we see available for purchase today.

What is an Antibody COVID test?

Antibody tests tell you if a person has been exposed to the SARS-CoV-2 virus by detecting antibodies in their blood. This can be done by a laboratory-based test such as AssureTech's EcoTest COVID-19 IgG/IgM Rapid Test Device.

Antibody tests like AssureTech's EcoTest COVID-19 IgG/IgM Rapid Test are not usually used to diagnose a current COVID-19 infection since it takes time for our body to produce the antibodies that fight the virus.

To get the most accurate representation of the SARS-CoV-2 pandemic, we can use antibody tests such as the EcoTest COVID-19 IgG/IgM Rapid Test from AssureTech to track the spread of the disease. As a country, we can use antibody tests to determine and access herd immunity. Herd immunity occurs when most of a population is immune to an infectious disease. Herd immunity provides herd protection to those who are not immune to the disease, such as COVID-19.

An example of herd immunity would be if 70% of a population were to be immune to the coronavirus, then 7 out of every 10 people would no longer contract thus spread COVID-19. Infectious diseases can be kept under control when herd immunity is achieved.

Tests such as AssureTech's EcoTest COVID-19 IgG/IgM Rapid Test distinguishes between IgM and IgG which indicates how long a person has been infected with SARS-CoV-2.

Vaccines for COVID-19 and COVID-19 testing go hand in hand. President Biden recently said he thinks anyone who wants a vaccine will be able to get it by spring and expects the US will soon be able to vaccinate 1.5 million people a day. IgG/IgM rapid tests can help prioritize vaccinations for those that need them.

Why Do Some Antibody Tests Fail?

With any antibody test, there are situations where an antibody test may result “negative”, when in fact the person may have SARS-CoV-2. Unfortunately, a negative test result may occur if the COVID-19 test was taken too soon after the coronavirus infection because the antibodies in the body haven’t been produced yet. Additionally, although in rarer cases, a false positive may occur if the person who has taken the SARS-CoV-2 rapid test was previously infected with another coronavirus, resulting in what’s called cross-reactivity.

Since COVID-19 is a novel virus, meaning it has not been previously recorded in humans, there’s a lot we still do not know. It’s likely that antibodies protect from re-infection of SARS-CoV-2 for up to 120 days. As we continue to learn more about COVID-19, this information will become available and can be used to our advantage when identifying the transmission and infection of the virus.

Antibody levels decline after two months, meaning it’s a short window for antibody testing when identifying when somebody has been infected. For that reason, antibody testing and it’s results should be interpreted and approached with a level of caution.

Where are SARS-CoV-2 antibody tests available?

There are a few antibody tests available, including the Rapid COVID-19 IgG/IgM Test. AssureTech's EcoTest COVID-19 IgG/IgM Rapid Test Device is an in-vitro immunoassay test that provides direct and qualitative detection of the anti-SARS-CoV-2 IgM and anti-SARS-CoV-2 IgG in human blood, serum or plasma. At Code1Supply, our EcoTest has been validated by the FDA and found to have 100% Sensitivity for IgM (30/30) and 98.8% Specificity for IgM.

EcoTest is one of only a few COVID-19 rapid antibody tests that have both FDA Emergency Use Authorization and that detect two types of antibodies, IgM and IgG. IgM antibodies peak early in the disease and IgG peaks later during the illness. There is no other COVID Rapid Antibody test like it on the market.

Where are SARS-CoV-2 antigen tests available?

Whereas antibody tests reveal if a person has had the novel coronavirus, antigen tests reveal if a person is currently infected with the SARS-CoV-2 virus. Once the infection from SARS-CoV-2 has gone, the antigen will then disappear.

Antigen tests detect the spike proteins found on the surface of the SARS-CoV-2 virus. Antigen tests produce rapid results, are affordable, and provide a more manageable use for point of care.

Code1Supply has the CareStart COVID-19 Rapid Antigen Test, which allows for rapid results on a larger scale. Our CareStart COVID-19 Rapid Antigen Test will test for acute infection in symptomatic patients with 88.4% sensitivity and 100% specificity.
