COVID-19 IgG Antibody Test
Note: COVID-19 IgG Antibody Test SHOULD NOT BE USED to diagnose Covid-19According to ICMR Advisory Dated 23-June-2020:
"IgG antibodies generally start appearing after two weeks of onset of infection, once the individual has recovered after infection and last for several months. Therefore, the IgG test is not useful for detecting acute infection. However, detection of IgG antibodies for SARS-CoV-2 may be useful in the following situations:
- Serosurveys to understand the proportion of population exposed to infection with SARS-CoV-2 including asymptomatic individuals. Depending upon the level of seroprevalence of infection, appropriate public health interventions can be planned and implemented for prevention and control of the disease. Periodic serosurveys are useful to guide the policy makers.
- Survey in high risk or vulnerable populations (health care workers, frontline workers, immunocompromised individuals, individuals in containment zones etc) to know who has been infected in the past and has now recovered."
What is the COVID-19 IgG Antibody test?
The Covid-19 IgG Antibody test is intended for use as an aid in identifying individuals with an adaptive immune response to SARS-CoV-2, indicating recent or prior infection. The Anti-SARS-CoV-2 IgG test should not be used to diagnose acute SARS-CoV-2 infection. Results are for the detection of SARS-CoV-2 IgG antibodies.
How much does the COVID-19 IgG Antibody Test cost?
Focusing on affordability, we at HOD have made a conscientious effort to price the test as cost-effectively as possible.

What do the Covid-19 IgG Test Results mean?Please find a suggestive test interpretation for the results, as suggested by Ortho Clinical Diagnostics.
- A Reactive test result indicates that IgG antibodies to SARS-CoV-2 were detected, and you are likely to have or previously had COVID-19 and that you have developed an antibody response to the virus
- The referring doctor/healthcare provider will work with you to determine how best to care for you based on the test results along with other factors of your medical history, including any previous symptoms, possible exposure to COVID-19, and the location of places you have recently traveled.
- A Non-Reactive test result means that the IgG antibodies to the virus that causes COVID-19 were not found in your sample.
- However, it is possible for this test to give a Non-Reactive result that is incorrect (false Non-Reactive) in some people with COVID-19 infection. A False Non-Reactive result may occur if you are tested early in your illness and your body hasn’t had time to produce IgG antibodies to infection. This means that you could possibly still have COVID-19 even though the test is Non-Reactive. If this is the case, your doctor/healthcare provider will consider the test result together with all other aspects of your medical history (such as symptoms, possible exposures, and geographical location of places you have recently traveled) in deciding how to care for you.
- It is important that you work with your doctor/healthcare provider to help you understand the next steps you should take.
How is the Covid-19 IgG Test Performed?Please note that the Covid-19 IgG Antibody Test is a blood test and not a swab test. At House Of Diagnostics we are performing Anti-SARS-Cov2-IgG, using C.L.I.A. (Chemi-Luminescence Immuno Assay) Testing on our high-throughput VITROS 5600 Systems, manufactured by Ortho Clinical Diagnostics. The Reagent kits we use known as VITROS Anti-SARS-CoV-2 IgG are US FDA EUA Approved and are being used in several countries globally. For your interest, please find an interesting video regarding a study on the performance of the test on the VITROS Platform below.
How long do the reports take?As of July-2020, House Of Diagnostics (HOD) has commenced offering the VITROS Anti-SARS-Cov-2-IgG Tests, on two of our high throughput VITROS 5600 Systems. Our two systems combined can yield several hundred test results per hour, enabling us to deliver the test results within the Same Day if samples are collected before 2PM and the relevant documentation is completed.
Who should get the test done on priority?According to ICMR Advisory Dated 23-June-2020
The IgG Test should be prioritized for the following groups of individuals:
