Diagnostics
A single TSH is the most common thyroid test — and the reason so many people are told they're 'normal' while still feeling awful. Here's the full panel we run, and what each marker tells us.
The Problem
TSH is a pituitary hormone that tells the thyroid to work harder or ease off. It's a useful screen, but it's an indirect signal — not a measurement of how much active hormone is actually reaching your cells. People with the same TSH can feel completely different, and early autoimmune disease can be well underway while TSH still reads 'normal.'
The Panel
A thorough evaluation looks at the whole system:
Together these reveal not just whether you're hypothyroid, but why, and whether you convert T4 to T3 well — which guides treatment choice.
Interpretation
Reference ranges describe a broad population, not your optimal. A result at the edge of 'normal' paired with classic symptoms tells a very different story than the same number in someone who feels great. We interpret your panel alongside your symptoms and history — and use it to decide between levothyroxine, T3/T4 combination, or desiccated thyroid.
