Covid-19 Antibody Testing

EcoTest COVID-19 IgG/IgM Antibody Rapid Testing is available for $40. We accept cash, check, credit card or Health Savings Account payments. We are unable to bill insurance, Medicare or Medicaid for this testing.

The test will be conducted at our location: 2001 Independence St. in Cape Girardeau, MO. A finger stick will be necessary for this test. Test results will be available in 15-20 minutes. There are no restrictions as to who may be tested.

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 (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 ten 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. It is unknown how much protection antibodies provide against reinfection. IgG antibody levels peak 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 infects. 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.

On average, IgM antibodies are produced by someone with an active COVID-19 infection around 4 to 7 days after infection. These antibodies typically disappear after 28 days from initial production.

The EcoTest COVID-19 IgG/IgM Rapid Test Device is an in-vitro immunoassay for qualitative detection of anti-SARS-CoV-2 IgG/IgM antibodies in human whole blood (fingerstick).

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.

• Antibody tests cannot guarantee 100% accuracy with regards to positive or negative test results or immunity to reinfection.

• 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.
