Fatigue that doesn't match your lifestyle. Feeling cold when others are comfortable. Weight that won't budge despite your effort. Hair thinning, dry skin, brain fog, low mood. Many women are told their thyroid is "normal" based on a single TSH measurement, and they leave the appointment still feeling exactly the same.
This panel is built for the woman who suspects her thyroid is involved and wants real answers. It looks beyond TSH at the active thyroid hormones, the autoimmune markers, and the nutrients that make thyroid function possible.
Anyone who suspects their thyroid may be part of the picture, men or women.
Especially valuable if your TSH has come back "normal" while you still have symptoms, if thyroid issues run in your family, if you've had a thyroid diagnosis and want a fuller view of your current status, or if you're in perimenopause and noticing symptoms that overlap with thyroid dysfunction.
TSH alone misses a lot. It measures the brain's signal to the thyroid, but it doesn't tell you whether the thyroid is making enough hormone, whether that hormone is being converted to its active form, whether autoimmune activity is quietly damaging the thyroid, or whether the nutrients the thyroid needs are actually present.
This panel gives you all of it. It's the same comprehensive look a functional clinician would order, including markers like reverse T3, both thyroid antibodies, selenium, and iodine that are rarely checked in conventional care.
TSH (thyroid-stimulating hormone). The brain's signal to the thyroid, telling it how much hormone to produce. The most commonly ordered thyroid marker, but rarely enough on its own.
Free T4. The main hormone produced by the thyroid. "Free" means the active form available to your body, not bound to proteins.
Free T3. The more active thyroid hormone, converted from T4 in the body's tissues. Often the marker most closely tied to how you actually feel.
Reverse T3. An inactive form of T3 that the body produces under stress, illness, or nutrient depletion. Elevated reverse T3 can explain why someone has "normal" thyroid labs but still feels hypothyroid.
Thyroid peroxidase antibodies (TPO). An autoimmune marker. Elevated levels can point to Hashimoto's thyroiditis, often years before standard thyroid labs become abnormal.
Thyroglobulin antibodies. A second autoimmune thyroid marker. Reading TPO and thyroglobulin antibodies together gives a more complete picture of autoimmune thyroid activity.
Selenium, RBC. A mineral essential for converting T4 into the active T3 your body actually uses. Low selenium can quietly impair thyroid function even when the thyroid itself is healthy.
Iodine, random urine. The raw material the thyroid uses to make thyroid hormone. Both deficiency and excess can disrupt thyroid function, and iodine status is rarely checked in conventional care. Requires a urine sample in addition to your blood draw.
Numbers on a page are data, not a diagnosis or a treatment plan. Thyroid function is influenced by stress, nutrients, medications, autoimmune activity, and other factors that a single set of results can't fully explain on their own.
If you'd like help understanding what your results mean, you have options.
For residents of Virginia, Maryland, DC, and Delaware, you can book an interpretation visit with Discreet Health for a clear, educational walk-through of your numbers.
If you live elsewhere, we recommend following up with a licensed clinician in your state.
If you're looking for a treatment plan or ongoing care beyond interpretation, that lives in our clinical programs (available only to residents of VA, MD, DC, and DE).
Biotin
If you take biotin or hair, skin, and nail supplements, stop them at least 2 to 3 days before your draw, as biotin can interfere with thyroid test results.
Urine Sample
The iodine portion of this panel requires a urine sample in addition to your blood draw. You'll be able to provide both during the same lab visit.
A dried urine test that measures sex hormones, adrenal hormones, and the metabolites your body produces as it processes them. Often chosen by women already on hormone therapy who want additional detail. We're upfront about where this test is useful and where blood work gives us more reliable answers.
A look at how your cortisol rises, falls, and settles across the day. Useful for understanding stress patterns, sleep issues, and HPA axis dysregulation when blood cortisol alone doesn't tell the full story.
A comprehensive stool test that identifies gut bacteria, yeast, parasites, and markers of digestion, inflammation, and intestinal barrier function. Often chosen by women investigating digestive symptoms or the gut-hormone connection.
A urine-based test that measures mycotoxins (toxic byproducts of mold) in your body. Often chosen by women with a history of water-damaged buildings or unexplained symptoms that haven't responded to other interventions.
An at-home test that uses DNA analysis to identify the bacteria, yeast, and organisms living in your vaginal microbiome. Often chosen by women with recurrent symptoms or those investigating the connection between hormones, the gut, and vaginal health.
