Thyroid care for hypothyroidism, Hashimoto's, and symptoms that haven't resolved on treatment. TSH is the right first test in most situations — when symptoms persist, the useful question is what else deserves a look.
Thyroid symptoms are rarely dramatic and rarely isolated. These are what people most often describe when thyroid disease turns out to be part of the picture.
Whether you have a confirmed diagnosis, an abnormal result nobody explained, or symptoms without answers yet.
Diagnosis, treatment, and ongoing medication management.
Autoimmune thyroid disease, including antibody-positive patients with normal thyroid function.
Including subclinical hypothyroidism, where treatment decisions genuinely depend on context.
Dose adjustment, timing, absorption, and monitoring over time.
When your TSH is in range and you still don't feel well.
Where thyroid and hormonal changes produce overlapping symptoms.
Systematic evaluation when thyroid is one of several possibilities.
Review of prior results and what they do and don't establish.
I look at your symptoms, history, medications, prior results, and the testing that is clinically appropriate for you. That may include more than a TSH, but more testing is not automatically better. The goal is to understand the full context, rule out other causes of your symptoms, and make evidence-informed decisions together.

What you're experiencing, how long it's been going on, and what's changed.
Reviewed before we meet, including results you were told were normal.
Including timing and absorption, which affect thyroid treatment more than most people expect.
TSH first in most cases, with free T4, free T3, or antibodies when the situation calls for it.
Iron deficiency, sleep disruption, mood conditions, and nutritional gaps produce a nearly identical picture.
Wondering whether your thyroid symptoms have been fully evaluated?
Start with a free 15-minute intro callIf you've been told your thyroid is normal but still feel unwell, this is usually where the explanation starts. Thyroid hormone moves through several steps before it does anything.
Simplified for clarity. Absorption, medication timing, other illness, and nutritional status all influence this pathway, and the picture differs in hyperthyroidism.
Each marker answers a different question. Which ones are appropriate depends on your symptoms, history, whether you're already on treatment, and what earlier results showed.
| TSHIs the pituitary asking for more or less thyroid hormone? | Made by the pituitary rather than the thyroid. It's a sensitive first-line screen for primary hypothyroidism and appropriate on its own in many situations. Less reliable in central hypothyroidism, during acute illness, and in early pregnancy. |
|---|---|
| Free T4How much thyroid hormone is available? | The unbound hormone circulating in your blood. Usually the next test when TSH is abnormal, when central hypothyroidism is a consideration, or when adjusting treatment. |
| Free T3How much of the more active form is circulating? | Most circulating hormone is T4, some of which becomes T3. Free T3 reflects what's in the blood — it doesn't measure what individual tissues receive, and it isn't a standalone test for conversion. Most often useful in specific situations rather than routinely. |
| TPO antibodiesIs an autoimmune process such as Hashimoto's present? | Identifies autoimmune thyroiditis, the most common cause of hypothyroidism in this country. Often detectable before TSH changes. A positive result doesn't by itself mean treatment is needed. |
More testing isn't automatically better. Reverse T3 is one I rarely order — the evidence for acting on it is thin, and I'd rather say so than order it because it's available.
Ongoing thyroid care with one provider — medication monitoring, routine follow-up, repeat testing at sensible intervals, and coordination over time.
Book a Comprehensive Intake Visit See what's included →Time-limited, structured support when symptoms are persistent or complex and deeper evaluation with closer follow-up is appropriate. Not something every thyroid patient needs.
Book a Root Cause Review See the programs →This page is general education, not medical advice for your situation. What's right for you depends on your history, medications, and results.
Related reading What a TSH alone can and can't tell you about your thyroidOften, yes. TSH is a sensitive first-line screen and appropriate by itself in many situations. Whether to add free T4, free T3, or thyroid antibodies depends on your symptoms, your history, whether you're already on treatment, and what the TSH actually showed.
That's worth taking seriously rather than dismissing. Depending on your history, that might mean looking at free T4 and antibodies — and it also means checking iron studies with ferritin, B12, and vitamin D, because those produce a nearly identical picture and are frequently the actual explanation.
Yes. That includes antibody-positive patients whose thyroid function is still normal, where the question is monitoring rather than treatment, and patients already on medication who want closer attention to how they actually feel.
TPO antibodies identify autoimmune thyroiditis — Hashimoto's — the most common cause of hypothyroidism in the United States. They're often detectable before TSH shifts. A positive result doesn't automatically mean treatment; it does change how closely we monitor and what to expect over time.
Worth investigating rather than accepting. I'd start with the practical things — dose, timing, and absorption, since levothyroxine interacts with calcium, iron, coffee, and meal timing. From there we'd look at what else could be contributing. Sometimes the answer is thyroid-related and sometimes it isn't.
When there's a clinical reason to. I'm not opposed to either and I'm not going to start there by default. The evidence for combination therapy is mixed, so what I want is a reason specific to you and a plan for how we'll judge whether it helped.
Thyroid evaluation and standard labs are typically billed through your plan when you're in-network. I accept Aetna, Anthem, BlueCross BlueShield and Medicare in both states, Cigna in Connecticut, and Medicaid in Colorado.
