What does a positive spike protein antibody mean?

Your Spike Protein Antibody results will be reported as a reference range: >/= 0.80 U/mL: This is a positive result for anti-SARS CoV-2S. A positive result means your body’s immune system has generated a response to the COVID-19 vaccine. It may also mean your body’s immune system has generated a response to a prior COVID-19 infection.

What does a positive Cov-2 blood test mean?

>/= 0.80 U/mL: This is a positive result for anti-SARS CoV-2S. A positive result means your body’s immune system has generated a response to the COVID-19 vaccine. It may also mean your body’s immune system has generated a response to a prior COVID-19 infection.

What does a positive covid-19 antibody test mean?

A positive result means your body’s immune system has generated a response to the COVID-19 vaccine. It may also mean your body’s immune system has generated a response to a prior COVID-19 infection. The test is not able to differentiate whether the antibodies produced were in response to the vaccine or to a prior infection.

Where are anti P1 antibodies found in the body?

Anti-P1 is frequently found in the sera of P1 negative individuals and is often naturally occurring. Anti-P1 is primarily found as an IgM antibody, but may be seen as IgG.

Why do I have TPO antibodies in my blood?

The presence of TPO antibodies in your blood suggests that the cause of thyroid disease is an autoimmune disorder, such as Hashimoto’s disease or Graves’ disease. In autoimmune disorders, your immune system makes antibodies that mistakenly attack normal tissue.

Can a pregnancy be affected by anti-P1 antibodies?

The P1 antibody identified in this case study was most likely a naturally occurring anti-P1, and the patient’s pregnancy should not be affected. Since examples of IgG anti-P1 are rare and antigen expression is weak during fetal gestation, anti-P1 has not been found to cause hemolytic disease of the fetus and newborn (HDFN). 2,6
