Covid-19 Antibody Test



Vibrant has developed a novel test for COVID-19. Vibrant’s COVID-19 panel is a highly sensitive and accurate serum assay for viral antibodies.


Vibrant’s COVID-19 ImmuneCheck looks specifically for IgM, IgA, and IgG antibodies against the spike proteins and 4 viral antigens of Covid-19 that will help assess your immunity against this novel virus.


The first FDA Emergency Use Authorized test on dried blood spot to test for the presence of COVID-19 antibodies with Vibrant Labs Ab Assay Test.

Why Test Antibodies to COVID-19?


Antibodies have been found to be highly sensitive biomarkers in infectious disease diagnosis. Previous studies on SARS, MERS, and more recently the ones on SARS-CoV2 have shown IgM antibodies to appear about 3 days from infection and IgG antibodies appear after 8 days.


Profiling an individual’s antibody response is the only way to determine infections with few or no symptoms.


Exceptional degree of sensitivity 98.1% and specificity 98.6% with a venipuncture-based SST collection.

This test is for asymptomatic populations


According to the CDC, “the signs and symptoms of COVID-19 present at illness onset vary, but over the course of the disease, most persons with COVID-19 will experience the following.”

  • Fever (83–99%)
  • Cough (59–82%)
  • Fatigue (44–70%)
  • Anorexia (40–84%)
  • Shortness of breath (31–40%)
  • Sputum production (28–33%)
  • Myalgia (11–35%)

**If you present with these symptoms, please seek immediate health advice by contacting your primary care provider or Urgent Care as this test in not appropriate for symptomatic/active infections.


As of June 4, 2020 Vibrant America is the First and Only Lab to obtain FDA EUA approval for Covid-19 dried blood spot antibody collection.
