Why Normal Labs Don’t Always Equal Normal Life

When it comes to thyroid health, most conventional doctors focus on just one lab marker: TSH (Thyroid Stimulating Hormone).
But here’s the truth: TSH is just the tip of the iceberg—and it leaves millions of women misdiagnosed, dismissed, or stuck in a cycle of fatigue, brain fog, stubborn weight gain, and feeling like “something’s off.”
Let’s unpack why TSH isn’t the whole story—and what else you need to look at to finally feel like yourself again.
Why TSH Isn’t Enough
You can have a TSH that’s “in range”… and still:
- Feel tired no matter how much you sleep
- Struggle to lose weight despite eating clean
- Deal with depression, anxiety, or mood swings
- Experience brain fog, dry skin, hair thinning, and cold hands/feet
That’s because TSH is only one piece of the puzzle—and it doesn’t tell us what’s happening at the cellular level.

The Full ThyroSisters Panel: What’s Under the Iceberg
At ThyroSisters, we look at everything that could be affecting your thyroid, hormones, metabolism, and brain function. Think of it as a functional “deep dive”—not just a quick glance at your labs. Here’s a peek into what we include:
MARKER |
WHY IT MATTERS |
---|---|
FREE T3 | The active form of thyroid hormone—your feel-good, energy-giving hormone. |
FREE T4 | The storage form. Your body must convert it into T3. |
Reverse T3 | Acts like a blocker. Too much? Your T3 can’t work properly. |
TPO L& TGB Antibodies | Reveal Hashimoto’s, an autoimmune condition often missed for years. |
T3 Uptake, T7, and more | Help uncover inflammation, nutrient needs, and hormone conversion issues. |
Still Feel Off with Normal Labs Results?

If you’ve ever been told:
- “Your TSH is normal.”
- “It’s probably stress.”
- “Let’s wait and retest next year…”
…yet your body is telling you a different story—you’re not imagining things. You’re just missing the full picture.
