Understanding Lab Tests for Anxiety Disorders
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Anxiety disorders are mental health conditions typically diagnosed through clinical evaluation and psychological assessment. While there is no single blood test to diagnose anxiety disorders directly, laboratory testing plays a valuable supporting role by evaluating biological factors that may contribute to anxiety symptoms.
Recommended Test
Serotonin, Serum
This test measures serotonin levels in the blood, a key neurotransmitter that plays a crucial role in mood regulation and behavior. Both elevated and decreased serotonin levels have been associated with anxiety disorders, making this test valuable for understanding potential biochemical factors contributing to anxiety symptoms.

Why Blood Testing is Important for Anxiety Evaluation
Blood tests are fundamental for assessing the biochemical aspects of anxiety disorders. Testing can help identify neurotransmitter imbalances, rule out medical conditions that mimic anxiety symptoms, and provide insights into the body's physiological responses that may be contributing to anxiety.
Understanding the Connection
Serotonin is often called the 'feel-good' neurotransmitter because of its important role in mood stability. When serotonin levels are imbalanced, it can affect emotional regulation and contribute to anxiety symptoms. Testing serotonin levels provides healthcare providers with important information about neurotransmitter function that may be influencing a patient's anxiety.
