Anti-Streptococcal A (IgG)

Optimal Result: 0.1 - 10 Units.

The marker "Anti-Streptococcal A (IgG)" is a specialized test designed to detect the presence of IgG antibodies against Streptococcus A bacteria in the blood. Streptococcus A is a type of bacteria that can cause various infections, ranging from mild throat infections (like strep throat) to more severe diseases such as rheumatic fever, which can affect the heart, joints, skin, and brain.

The presence of IgG antibodies specifically indicates a past or ongoing immune response to this bacterium, suggesting previous exposure or infection.

What does it mean if your Anti-Streptococcal A (IgG) result is too high?

Elevated levels of Anti-Streptococcal A (IgG) antibodies indicate that the body has been exposed to the Streptococcus A bacteria and has mounted an immune response to combat this infection. When these antibody levels are high, it suggests that either the individual has recently been infected by Streptococcus A, leading to the production of these antibodies as a part of the body's natural defense mechanism, or the person had an infection in the past and the immune system remains on high alert. In some cases, elevated levels can also be a sign of an ongoing, possibly subclinical, infection where the symptoms might not be overtly noticeable.

Beyond indicating a past or present infection, these elevated antibody levels are significant because they can be associated with complications such as rheumatic fever or other post-streptococcal conditions, which may affect the heart, joints, and nervous system. In the context of neurological symptoms or conditions, high levels of these antibodies might suggest that the streptococcal infection could be playing a role in the individual's health issues, either through direct effects or by triggering autoimmune responses where the body mistakenly attacks its own tissues. Understanding these levels helps healthcare providers to not only address the immediate concerns related to streptococcal infections but also to consider broader implications for the patient's overall health and potential need for further investigation or treatment.
