Neurotransmitter Testing as Road Signs for Path to Stronger Health

[@ony5447]

Hi Dr., I have a question regarding testing. I found a company in UK that is doing Neurotransmitter Testing home kit (with filter paper strip urine collection) but the samples are sent to USA to a ZRT Laboratory for testing. Therefore the samples will arrive in USA in probably around 7 days from sampling. Would the urine strips still be valid for testing? Could they become nonviable due to time, temperature, etc and affect the results? Thank you.

Hi, ZRT is a well known lab in the integrative care arena in the US. This is a perfect question for the lab as they will have the data. I would advise emailing ZRT directly for dried urine stability insight.
