SARS-CoV-2 IgG

Elevated levels of SARS-CoV-2 IgG might mean that your body has come across the COVID-19 virus before. These antibodies are like your body's personal security team, helping to protect you from the virus. Keep in mind that when you take the test and how strong your body's defense response is can affect the levels of these antibodies. Also, certain medications (like immunosuppressants) or health conditions that impact your immune system could play a role in the production of SARS-CoV-2 IgG.

Symptoms of high levels of SARS-CoV-2 IgG are typically not present, as this antibody is a response to a past infection rather than a cause of current illness.

Low levels of SARS-CoV-2 IgG might mean that your body hasn't come across the virus that causes COVID-19, or it could be that your immune system hasn't made a strong response to it. This can happen for different reasons, like taking the test too soon after being exposed to the virus, or because everyone's immune system reacts differently. Some medications, like drugs that suppress the immune system, could also affect how much of this antibody your body makes. Additionally, certain health conditions that affect the immune system might make it harder for your body to produce antibodies when fighting infections.

Symptoms of low levels of SARS-CoV-2 IgG are typically not noticeable, as this test measures immune response rather than disease presence or severity.
