Description

What is Covid Antibody IgG (Qualitative)?

Covid-19 Antibody IgG (Qualitative) helps in detecting the presence of specific IgG antibodies against COVID- 19. Your body makes antibodies when you get an infection and these antibodies help fight against it. If you have COVID-19 antibodies in your blood, it’s likely you’ve had the infection or have been exposed to the infection before.

Covid-19 Antibody IgG (Qualitative):

• Measures the presence of IgG antibodies against COVID-19
• Measures Neutralizing Antibody
• Detects prior exposure to the virus
• Detects vaccine response of the body
• Unit of measurement: Index value
• Reportable values:
  < 1.0 : Negative – Indicates absence of SARS-CoV-2 IgG Antibodies
  ≥ 1.0 : Positive – Indicates presence of SARS-CoV-2 IgG Antibodies

How does Covid-19 Antibody IgG (Qualitative) compare to Covid-19 Antibody IgG (Quantitative)?

Similarities:

• Measures Neutralizing Antibody 
• Detects prior exposure to the virus    
• Detects vaccine response of the body

Differences: 

• The Qualitative test measures the presence of antibodies against COVID-19 while the Quantitative test measures the presence and quantifies the specific amount of antibodies of COVID-19
• Unit of measurement: Index value for Qualitative test vs AU/ml for Quantitative test
• Reportable values:
  Qualitative:
  < 1.0 : Negative
  ≥ 1.0 : Positive
  
  Quantitative:
  < 50.0 AU/ml : Negative
  >=50.0 – 80,000 AU/ml : Positive

Note: Covid Antibody IgG (Qualitative) test only helps in detecting the presence of antibodies and is not meant to be used for diagnosis of active Covid-19 infection.

Interpretations

< 1.0 : Negative – Indicates absence of SARS-CoV-2 IgG Antibodies

≥ 1.0 : Positive – Indicates presence of SARS-CoV-2 IgG Antibodies
