GetTested’s **Neurotransmitters Base Test** is an at-home lab test that measures key neurotransmitters involved in mood, stress response, and cognitive function. The test analyzes serotonin, dopamine, adrenaline, and noradrenaline, along with creatinine and the noradrenaline/adrenaline ratio, providing insight into your body’s neurochemical balance. These markers play an important role in regulating emotions, behavior, sleep, and stress levels, and imbalances may be linked to symptoms such as fatigue, anxiety, or low mood.
