Testing neurotransmitters in patients with psychological conditions can help target specific imbalances – getting to the root of persistent issues such as adrenal dysfunction, mood disorders, lack of ambition and lack of appetite.

Neurotransmitter testing gives practitioners a diagnostic edge over the traditional psychological inventory. It offers the advantage of zeroing in on which therapies are best suited for an individual patient.

Combining neurotransmitter testing with other hormone testing gives practitioners an even deeper insight into a patient’s individual neurochemistry.

Patients who should be tested include those who suffer from:

  • Insomnia
  • Depression
  • Persistent fatigue
  • Poor memory
  • Anxiety
  • Low libido
  • Feeling perpetually drained

Urine Collection

ZRT Laboratory’s is the only lab to offer a standard 24-hour evaluation of a patient’s neurotransmitter function, which gives a more accurate assessment of individual neurochemistry. Instead of relying on a single time point, ZRT averages together four daily collections to create this more complete picture.
