What's this test for?

This test is ideal if you're experiencing unexplained fatigue, sudden weight changes, mood swings, feeling too hot or too cold, or brain fog. It provides a complete picture of your thyroid function by measuring all the key thyroid hormones that control your metabolism, energy levels, and overall well-being. Many people use this test when they suspect their symptoms are thyroid-related but want comprehensive answers beyond just a basic TSH check.

How should I prepare for this test?

Samples should not be collected during or soon after receiving Heparin medication. No other special preparation is typically required for this thyroid panel, though it's best to maintain your normal routine and medication schedule unless your doctor advises otherwise. The test can be done at any time of day.

What's included in this test?

T3, Free T4, Free, Direct Dialysis T3, Total T3 Reverse, LC/MS/Ms

This comprehensive panel measures all the critical thyroid hormones including TSH (which signals your thyroid to produce hormones), Free T4 and Total T4 (the main hormone your thyroid produces), Free T3 and Total T3 (the active form your body uses for energy), and Reverse T3 (which can block thyroid function). Together, these measurements provide a complete picture of how well your thyroid is working, why you might be experiencing symptoms, and whether conversion problems or hormone resistance could be affecting your metabolism and energy levels.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your thyroid hormone levels mean for your energy, weight, and overall health. These notes include personalized recommendations like dietary adjustments, supplement suggestions, lifestyle changes to support thyroid function, or whether you should follow up with an endocrinologist. You'll also get the standard lab report and can track your thyroid levels over time using our trends feature to see how your interventions are working or monitor medication effectiveness.
When will I get my results?
Your results will be ready in approximately 8 business days. If confirmation testing is required for any biomarker, the turnaround time may be extended to ensure accurate results. You'll be notified as soon as your complete results are available in your secure online account.
Who should consider getting this test?
This test is ideal for people experiencing unexplained fatigue, unexpected weight gain or difficulty losing weight, hair loss, mood changes, or temperature sensitivity. It's especially important for women over 35, anyone with a family history of thyroid disease, people who have been diagnosed with thyroid conditions and want comprehensive monitoring, or those who've had basic thyroid tests but still experience symptoms.
What symptoms indicate I may need this test?
Common symptoms include persistent tiredness despite adequate sleep, unexplained weight changes (especially stubborn weight gain), feeling unusually cold or hot, brain fog or difficulty concentrating, thinning hair, dry skin, constipation, irregular periods, or mood swings. If you're experiencing several of these symptoms together, a comprehensive thyroid evaluation can help identify whether thyroid imbalance is the underlying cause.
How can I naturally support my thyroid function?
Supporting thyroid health starts with ensuring adequate iodine and selenium intake through foods like fish, eggs, Brazil nuts, and dairy products. Getting consistent quality sleep, managing stress through yoga or meditation, and regular exercise can help balance thyroid hormones naturally. Avoiding excessive consumption of raw cruciferous vegetables, limiting processed foods, and reducing exposure to environmental toxins may also support optimal thyroid function.
What is TSH and why does it matter?
TSH (Thyroid Stimulating Hormone) is produced by your pituitary gland and tells your thyroid how much hormone to make. When your thyroid isn't producing enough hormone, TSH goes up as your body tries harder to stimulate it. When your thyroid produces too much, TSH drops. Think of it like a thermostat for your metabolism - it's one of the most important indicators of overall thyroid function and helps explain symptoms like fatigue, weight changes, and temperature sensitivity.
What does high TSH mean?
High TSH usually means your thyroid isn't producing enough thyroid hormone, a condition called hypothyroidism. Your pituitary gland is working overtime to try to stimulate your thyroid. This can cause fatigue, weight gain, feeling cold, constipation, dry skin, and brain fog. Elevated TSH may indicate you need thyroid hormone support, dietary changes, or further evaluation by a healthcare provider.

What this means

Your TSH is slightly elevated, which may indicate your thyroid is working harder than ideal to produce enough thyroid hormone. This can contribute to fatigue, weight gain, feeling cold, or difficulty concentrating, and may benefit from closer monitoring and lifestyle support.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
