Functional medicine testing

Root-cause lab testing, so treatment targets the cause, not the label.

What it means

Testing that finds the root cause

Functional medicine testing looks under the hood, using functional medicine lab testing to connect your biology to how you think and feel. At Sphosh Health, Dr. Koichi Tanji, ND, LMHC uses hormone, gut, food-sensitivity and nutrient testing to uncover the drivers behind anxiety, low mood, fatigue and focus, so your plan targets the cause instead of chasing symptoms.

  • Hormone, thyroid and adrenal (cortisol) testing
  • Gut and microbiome testing for the gut-brain axis
  • Food-sensitivity and nutrient testing
  • Genetic and methylation insights where they help

What to expect

What functional medicine testing looks like, step by step

Good testing is targeted, not scattershot. Here is how the process usually works at Sphosh Health, in our Bellevue office or by secure video anywhere in Washington.

  1. Start with your story. We choose tests from your symptoms and history, so we are answering real questions rather than running everything.
  2. The right panels. Depending on your picture, that may include hormone and thyroid or adrenal testing, gut and microbiome testing, food-sensitivity or nutrient panels, and where useful, genetic or methylation insights.
  3. Collection made simple. Many tests are straightforward blood draws or at-home kits; we explain exactly what each one involves.
  4. Results in plain language. We review what the numbers mean together, in context, a result is a clue, not a verdict.
  5. A root-cause plan. We translate the findings into concrete next steps around nutrition, lifestyle and, where it helps, medication.
