![]() ![]() Antibody tests may look for different antibodies that are only produced after natural infection. If indicated, a repeat test may yield more reliable results. The COVID-19 vaccine trains immune cells to notice and attack the signature spike protein. The most common reasons for equivocal results are presence of an immune response but unclear if against the infection being tested for (COVID-19 in this case) or similar infections (the common cold is a type of coronavirus). All Antibodies Are Binding Only a Subset Are Also neutralizing The most common target of vaccine design: Spike protein found to be important for SARS-CoV-2. If you had symptoms consistent with COVID-19 within the past 3 weeks and tested negative, repeat testing in 1-2 weeks may yield a positive result.Įquivocal: Your test results could not be interpreted as Positive or Negative. Please note, it may take 14-21 days to produce detectable levels of IgG following infection. This means you have not been infected with COVID-19. Negative: You tested negative for COVID-19 IgG antibody. Spike (S): Antibodies to the spike proteinare produced after vaccination1-3 Nucleocapsid (N): Antibodies to Nucleocapsididentify individuals who have had a recent or prior COVID-19 infection, but are not useful for detecting antibodies elicited by currently available SARS-CoV-2 vaccines. For patients testing higher then 2,500 U/mL, your results will be reported as “Greater Than 2,500 U/mL." Please note: A numerical value will be reported up to 2,500 U/mL. If youve not received a vaccine for Covid-19, testing for the spike protein can reveal whether youve previously been infected with Sars-CoV-2. It is yet undetermined what Antibody level is correlated to immunity against developing the COVID-19 infection ![]() ![]() A negative result means your immune system has not generated a measurable response to the COVID-19 vaccination and that you have likely not had the COVID-19 infection. < 0.80 U/mL: This is a negative result for anti SARS CoV-2S. The test is not able to differentiate whether the antibodies produced were in response to the vaccine or to a prior infection. What does the COVID-19 Rapid POC CE-IVD Test detect The test detects the presence of patient-generated antibodies against spike protein, the virus which causes. It may also mean your body’s immune system has generated a response to a prior COVID-19 infection. Spike protein is the focus of vaccines and convalescent plasma therapy, so levels of these antibodies correlate to. A positive result means your body’s immune system has generated a response to the COVID-19 vaccine. So it is a good target for antibody testing. >/= 0.80 U/mL: This is a positive result for anti-SARS CoV-2S. Your Spike Protein Antibody results will be reported as a reference range: ![]()
