Bordetella pertussis IgG

Elevated levels of Bordetella pertussis IgG might mean that your body has recently come across or is currently fighting the bacteria that causes whooping cough. You could have had a recent infection, even without showing symptoms, or your immune system might be responding to a whooping cough vaccine. Some medications that impact the immune system, like immunosuppressants or corticosteroids, could also potentially cause higher levels of these antibodies.

Symptoms of high levels of Bordetella pertussis IgG may not be noticeable, as the presence of these antibodies doesn't directly cause symptoms. However, if the elevated levels are due to an active infection, you might experience symptoms of whooping cough, such as severe coughing fits, difficulty breathing, and fatigue.

Low levels of Bordetella pertussis IgG might mean that your body hasn't come across the whooping cough germ before, or it's been a while since you last encountered it. This could happen if you haven't been vaccinated against whooping cough or haven't had the illness before. It's also possible that your body isn't making enough of this specific antibody, which could be due to factors like your age, overall health, or certain medications that affect your immune system. For example, some drugs like corticosteroids or immunosuppressants can impact your body's ability to produce antibodies.

Symptoms of low levels of Bordetella pertussis IgG may not be noticeable, as this simply reflects your immune system's history with the bacterium and does not directly cause symptoms. However, without this antibody, you might be more susceptible to contracting whooping cough, which can cause severe coughing fits, difficulty breathing, and other respiratory issues.
