What Is Anti-Dopamine Receptor 2 (IgG + IgA)?
The Anti-Dopamine Receptor 2 (DRD2) antibodies test measures immune reactivity to dopamine receptor 2 (DRD2) in the brain. Dopamine receptors play a crucial role in neurotransmission, regulating movement, cognition, mood, and behavior. The presence of IgG and IgA antibodies against DRD2 may indicate an autoimmune reaction targeting these receptors.
Why Is This Marker Important?
Dysregulation of dopamine receptor 2 is linked to neurological, psychiatric, and autoimmune conditions. Elevated Anti-DRD2 IgG or IgA levels may suggest:
- Neuroinflammation and autoimmune encephalopathy
- Basal ganglia dysfunction, potentially associated with movement disorders
- Neuropsychiatric symptoms, including OCD, tics, and mood disorders
- PANDAS/PANS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections)
- Post-infectious autoimmunity, particularly after bacterial or viral infections
Understanding IgG and IgA Results
- Elevated IgG: Suggests a systemic, chronic immune response against DRD2, potentially linked to long-term neuroinflammation.
- Elevated IgA: May indicate mucosal immune activation, such as gut-brain axis dysfunction or an ongoing autoimmune response.
Conditions Associated with Anti-DRD2 Antibodies
- Autoimmune encephalitis
- Basal ganglia-related movement disorders (e.g., Parkinson’s-like symptoms, dystonia)
- Schizophrenia and other psychiatric disorders
- Obsessive-compulsive disorder (OCD)
- Tic disorders and Tourette syndrome
- PANDAS/PANS (post-infectious neuroimmune conditions)
Potential Causes of Elevated Anti-DRD2 Antibodies
- Molecular mimicry (cross-reactivity from infections like streptococcus or viruses)
- Dysbiosis and leaky gut (gut-brain axis dysfunction)
- Chronic neuroinflammation
- Environmental triggers, including toxins or heavy metals
What to Do If Your Anti-DRD2 Antibodies Are Elevated
If this marker is elevated, further evaluation may be necessary. Potential next steps include:
- Functional neurology or immunology evaluation
- Checking for infections (e.g., Streptococcus, Lyme disease, viral triggers)
- Assessing gut health (intestinal permeability, microbiome imbalances)
- Addressing neuroinflammation with anti-inflammatory and neuroprotective strategies
- Considering autoimmune modulation therapies
Final Thoughts
The presence of Anti-Dopamine Receptor 2 (IgG + IgA) antibodies on the Neural Zoomer Plus panel may indicate an underlying autoimmune or neuroimmune process. Identifying and addressing potential triggers can be key to managing symptoms and restoring neurological balance. If you have concerns about your results, consult a healthcare professional specializing in neuroimmunology or functional medicine.

What Healthmatters Members Are Saying
I have been using Healthmatters.io since 2021. I travel all over the world and use different doctors and health facilities. This site has allowed me to consolidate all my various test results over 14 years in one place. And every doctor that I show this to has been impressed. Because with any health professional I talk to, I can pull up historical results in seconds. It is invaluable. Even going back to the same doctor, they usually do not have the historical results from their facility in a graph format. That has been very helpful.
