Testing Your COVID 19 Antibodies
Reviewed by Expert panel

Over a billion Covid shots have been administered in India since the vaccination drive began in January¹  last year. The first vaccine was administered on 16 January 2021, which means we reached this milestone in 278 days. Let me tell you about the test – the Quant IgG Spike Protein Antibody Test. To put it in simple words, this test assesses the levels of IgG antibodies and understands a person's immune response.

What is IgG antibody

Approximately 2–3 weeks after being infected by the SARS-CoV-2 coronavirus, antiviral antibodies of the IgG type develop in the blood. They act as proof that the body has responded against the virus. These antibodies can be retained in the body for at least six months. Just as our bodies produce antibodies in response to SARS-CoV-2 coronavirus, vaccination stimulates the body to produce antibodies too. 

What Is the Quant IgG Spike Protein Antibody Test

Besides determining the presence of antibodies, the Quant IgG Spike Protein Antibody Test for SARS-Cov-2 determines the numeric level of antibodies in the blood. These antibodies adhere to the spike protein of the virus and neutralize it. The Quant IgG Spike Protein Antibody Test identifies the quantity of IgG antibodies adhering to the virus' spike protein which can be used to determine a person's immune response to vaccines.

How accurate Is This Test?

As per the media coverage² it was found that the clinical performance of the Quant IgG Spike Protein Antibody Test find 99.60% specificity and 99.35% sensitivity in the outcome. The test therefore has a high degree of reliability.

What Will This Test Tell You?      

The Quant IgG Spike Protein Antibody Test lets us know of our body’s immunity status by testing whether it has developed antibodies post vaccination

The Quant IgG Spike Protein Antibody Test also provide the following advantages:

  • Identify and monitor the immune response of an individual to vaccine, including research concerning how long a response may last

  • Assessing an individual's antibodies in order to determine eligibility and potency for convalescent plasma donation
