This guide is for the dried-urine LCMS neurotransmitter and diurnal hormone panel. The matching Advanced Neurotransmitter & Hormone Test II product page lists four timed urine collections. Use the collection instructions PDF for the exact times, preparation requirements and card-by-card steps; those details can be panel-specific.
What the test measures
The product page describes a 50-measurement dried-urine panel covering neurotransmitters and related metabolites, creatinine, and daily hormone markers measured across the day. Urinary results reflect substances excreted in urine; they do not directly measure neurotransmitter levels in the brain or establish the cause of symptoms.
Before you begin
- Read the full PDF and check that the test code on your requisition matches your kit.
- Set aside time for all four collection points and follow the exact schedule in the PDF. Don’t guess the timing or combine collections.
- Follow the preparation directions for food, drink, nicotine, medicines and supplements. The product page notes these can affect urinary results.
- Record your medicines and supplements on the requisition. Don’t stop prescribed medication or change treatment unless your prescribing clinician tells you to.
- Have the supplied filter cards and paperwork ready before your first collection.
Collect and dry each sample
At each scheduled collection time, follow the PDF’s instructions for applying the urine sample to the supplied filter card. Use the card specified for that time and complete any labelling details as directed. Keep the four timed samples separate, and allow each card to dry fully before packaging it. The exact collection method and handling steps are in the linked guide.
Return the kit
Once all cards are dry, pack them with the completed paperwork using the kit’s return instructions and packaging. The product page says results are normally available within 3–5 working days after the laboratory receives the samples.
Check suitability
The product page advises speaking with a healthcare professional before ordering if you are pregnant, breastfeeding, have kidney disease or are receiving treatment for a diagnosed condition. It also recommends discussing testing for anyone under 18 with their healthcare professional.
