Neuropsychological Functioning Profile (Screening) – Serum/Plasma Substance Content

What This Test Measures

Your blood sample will be analyzed for a range of neuroactive substances, including neurotransmitters (like dopamine and serotonin), neurotrophic factors (that support brain health), and metabolites (byproducts of brain activity). These substances play roles in mood, focus, and cognitive processing. The test uses a sensitive immunoassay method to detect these compounds at very low levels.

Why It’s Ordered

Your healthcare provider may recommend this test if you’re experiencing symptoms like persistent brain fog, difficulty concentrating, mood swings, or other signs of neurological or psychiatric concern. It can also be part of a broader evaluation for conditions like depression, ADHD, or neurological disorders.

Sample Collection and Preparation

You’ll have a small amount of blood drawn from a vein, usually in your arm. The blood is then separated into plasma or serum for testing. This process is quick and typically done in a clinical setting. You may feel slight discomfort, but it’s usually over quickly.

Test Results and Interpretation

Results are reviewed by a medical professional to compare against expected ranges for your age and health status. While this test doesn’t diagnose a specific condition, it can highlight imbalances that may warrant further investigation, such as additional blood tests, imaging, or specialized evaluations.
