For optimal and clinically relevant results, samples should be collected under normative conditions, ensuring consistency in collection procedures and tube handling. Patients should maintain their routine diet, medications, and supplements unless specifically instructed otherwise by their healthcare provider. This approach ensures accurate assessment based on their usual physiological state.
Suggested Items to Avoid:
- Diet: For 48 hours before, avoid phytoestrogen-rich foods (e.g., soy, flaxseeds, licorice) and dopamine influences (e.g., bananas, avocados, fava beans). Limit caffeine and alcohol.
- Supplements: Avoid tyrosine, quercetin, or Mucuna for 48 hours.
- Hydration: Avoid fluids 1 hours before each sample collection. Maintain normal hydration-avoid overhydrating to prevent dilution.
- Make note that this test is also age-restricted to those who are 14 years old or older.
