Another health condition that can cause antinuclear antibodies, such as cancer.A viral infection (antinuclear antibodies from a virus are usually temporary).But a negative ANA test doesn't completely rule out the possibility that you could have an autoimmune disorder.Ī positive result on an ANA test means that antinuclear antibodies were found in your blood. Your provider will use your ANA test results along with other tests and information about your health to make a diagnosis.Ī negative result on an ANA test means that antinuclear antibodies were not found in your blood, and you're less likely to have an autoimmune disorder. 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.Results from an ANA test alone cannot diagnose a specific disease. 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. Non-Reactive: You tested negative for COVID-19 IgG antibody. Please continue with universal precautions: social distancing, hand washing and when applicable PPE such as masks or gloves. It is unclear at this time if a positive IgG infers immunity against future COVID-19 infection. Some patients with past infections may not have experienced any symptoms. Reactive: You produced the COVID-19 IgG antibody and have a high likelihood of prior infection. 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. Please note, it may take 14-21 days to produce detectable levels of IgG. A common question is "My result was 1.3, does that mean I produced a little IgG and could be positive?" The answer is no.
Some patients with past infections may not have experienced symptoms. ≥ 1.4: This is a positive result and has a high likelihood of prior infection. Sunrise Labs will report your results as: If indicated, a repeat test may yield more reliable results. 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). 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. Negative: You tested negative for COVID-19 IgG antibody. Positive: You produced the COVID-19 IgG antibody and have a high likelihood of prior infection.
