Covid-19 Spike Protein Antibody Test

This blood test measures semi-quantitative antibodies directed against the spike protein of SARS-CoV-2, the virus that causes COVID-19. It helps identify whether an adaptive immune response has developed following infection or vaccination.

This test helps assess:
• Prior COVID-19 infection
• Immune response following vaccination
• Presence of spike protein antibodies
• Adaptive immune system response

What This Test Measures
The assay detects antibodies targeting the SARS-CoV-2 spike glycoprotein. Results are reported semi-quantitatively, meaning they provide an antibody level rather than simply positive or negative.

What Your Results May Mean
• Positive/Detectable Antibodies: Suggests prior infection and/or vaccination with an immune response.
• Negative/Undetectable Antibodies: May indicate no prior exposure, no measurable response, or testing performed too early.

Results should be interpreted in clinical context. Antibody presence does not guarantee immunity or protection from future infection.
