To Pee or Not to Pee?


Published on 12/27/17

Practitioners with a keen eye may have recently noticed a change within our NT collection guidelines allowing practitioners/patients the option of either a first or second morning urine void. What’s the deal?

Within the field of integrative medicine, the second morning void of urine has been the standard collection method for testing urinary neurotransmitters. However, new study has revealed that the first and second morning voids should provide both accurate and equivocal urinary neurotransmitter levels if fasting, exercise avoidance, and stress-control are maintained until the second morning void.

This is great news for practitioners testing children and adults who have difficulty continuing to fast until the second urine void of the day. Additionally, patients experiencing stressful morning schedules due to family matters, commuting, or strenuous exercise may want to consider choosing a first AM void, avoiding potential impact to the catecholamine levels in a second morning void.

Health care providers may now choose whichever collection time best fits the patient’s unique situation. It is recommended to be consistent in collection times with follow-up testing. Also, ensure the requisition form indicates which void was collected, as this information is valuable during laboratory analysis and for reference when comparing future test results. 

We are happy to bring this new information to our providers, as ease of collection is essential to the success of integrative practitioners seeking true and lasting healing for their patients.
