Anxiety disorders are mental health conditions characterized by excessive worry, fear, and physical symptoms that interfere with daily life. They are caused by imbalances in neurotransmitters like serotonin, GABA, and dopamine that regulate mood and stress responses. The Serotonin, Serum test is the most important test for evaluating biochemical factors contributing to anxiety disorders.

Anxiety disorders are caused by imbalances in brain neurotransmitters including serotonin, GABA (gamma-aminobutyric acid), dopamine, and norepinephrine. These chemical messengers regulate mood, fear responses, and stress reactions in the brain. When levels are too high or too low, it disrupts normal emotional regulation and can trigger persistent worry, panic attacks, and physical symptoms like rapid heartbeat and sweating. Genetic factors, chronic stress, traumatic experiences, and certain medical conditions can all contribute to these neurotransmitter imbalances.
The Serotonin, Serum test is the most important test for anxiety disorders because it measures levels of this critical mood-regulating neurotransmitter in your blood. Serotonin directly affects emotional stability, sleep patterns, and stress responses, and both high and low levels have been linked to various anxiety symptoms. This test provides valuable insight into whether biochemical imbalances are contributing to your anxiety, helping healthcare providers understand the physiological factors at play. While anxiety disorders are primarily diagnosed through clinical evaluation, serotonin testing offers concrete data about neurotransmitter function that can guide treatment decisions and rule out other medical causes of anxiety-like symptoms.
You should get tested if you experience persistent worry or fear that interferes with daily activities, frequent panic attacks with physical symptoms like chest pain or difficulty breathing, or avoidance of social situations or places due to overwhelming anxiety. Testing is also important if you have unexplained physical symptoms like constant fatigue, muscle tension, digestive problems, or sleep disturbances that could be related to anxiety. Consider testing if anxiety symptoms have lasted more than six months, if they are getting worse over time, or if you want to understand the biochemical factors that might be contributing to your mental health concerns before starting treatment.

What this means
Your serotonin levels are slightly below the optimal range. While this is not critically low, it may contribute to mood fluctuations, difficulty sleeping, or lower energy levels throughout the day. This could explain symptoms like persistent fatigue or feeling down.
