Understanding Lab Tests for Mental Disorders
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Mental disorders are complex conditions typically diagnosed through clinical evaluation, psychological assessments, and detailed patient history. While there is no single blood test to diagnose mental health conditions like depression, anxiety, or schizophrenia, laboratory testing plays a fundamental role in identifying potential contributing factors and supporting comprehensive mental health care.
Top Recommended Test
Omega 3 and Omega 6 Fatty Acids
This test evaluates essential fatty acid levels, particularly EPA (eicosapentaenoic acid), which plays a vital role in brain health and function. Research has shown that low levels of EPA are associated with various mental disorders including depression and schizophrenia. Assessing fatty acid status helps identify potential nutritional deficiencies that may be contributing to mental health symptoms.

The Role of Blood Testing in Mental Health Assessment
Blood tests are essential for assessing overall health and identifying underlying factors that may contribute to or worsen mental health symptoms. These tests can detect nutritional deficiencies, toxic exposures, and biochemical imbalances that might affect brain function and emotional well-being, providing valuable information to support treatment decisions.
Other Relevant Tests
Mercury Blood
This test measures mercury levels in the blood to detect potential toxic exposure. Chronic mercury exposure can significantly impact the nervous system and contribute to neurological and mental health symptoms including depression, anxiety, and mood disorders. Identifying elevated mercury levels is crucial for addressing this potential environmental contributor to mental health issues.
