What's this test for?

This test is ideal if you're experiencing unexplained fatigue, weight changes that won't budge, mood swings, feeling too hot or cold, hair loss, or brain fog. It helps identify thyroid disorders and autoimmune thyroid conditions that may be affecting your energy, metabolism, and overall well-being. Many people use this test when they suspect their symptoms are hormone-related but want concrete answers about what's really going on with their thyroid.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your thyroid levels mean for your energy, metabolism, and overall health. These notes include personalized recommendations like dietary changes, supplement suggestions, stress management tips, 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 lifestyle changes or medications are working.

What's included in this test?

This comprehensive thyroid panel measures TSH, Free T3, Total T3, Free T4, Reverse T3, Thyroid Peroxidase Antibodies (TPO), Thyroglobulin Antibodies, and Thyroid-Stimulating Immunoglobulin (TSI). This complete panel evaluates how well your thyroid is producing and converting hormones, which directly impacts your energy, weight, mood, and body temperature regulation. It also checks for autoimmune thyroid conditions like Hashimoto's or Graves' disease by measuring antibodies that can attack your thyroid. Together, these measurements provide a complete picture of your thyroid function and help identify the root cause of thyroid-related symptoms.

How should I prepare for this test?

You are not required to fast for this test, so you can eat and drink normally beforehand. However, samples should not be collected during or soon after heparin administration if you're receiving that medication. Results typically take about 8 business days, though if confirmation testing is needed, it may take a bit longer.

When will I get my results?

You can expect your results in approximately 8 business days after your sample is collected. In some cases, if confirmation testing is required for accuracy, the turnaround time may be extended slightly. You'll be notified as soon as your results are available and ready to review.

Who should consider getting this test?

This test is perfect for anyone experiencing unexplained fatigue, sudden weight changes, mood swings, temperature sensitivity, hair thinning, or irregular periods. It's especially important for women over 35, people with a family history of thyroid disease, anyone already being treated for thyroid conditions who needs comprehensive monitoring, or those who've had basic thyroid tests but still have symptoms.

What symptoms indicate I may need this test?

Common symptoms include persistent tiredness even after sleep, unexpected weight gain or difficulty losing weight, feeling unusually cold or hot, thinning hair or hair loss, dry skin, constipation, depression or anxiety, brain fog or trouble concentrating, and irregular or heavy menstrual periods. If you're experiencing several of these symptoms together, a thyroid issue could be 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, seafood, eggs, Brazil nuts, and dairy products. Getting 7-8 hours of quality sleep, managing stress through meditation or yoga, and regular exercise can help balance thyroid hormones. Reducing processed foods, limiting goitrogens like raw cruciferous vegetables if you have thyroid issues, and avoiding excessive soy products may also help optimize 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 thyroid hormone to make. When TSH is high, it means your thyroid isn't producing enough hormone and your body is trying to stimulate it to work harder. When TSH is low, it often means your thyroid is overactive. TSH is typically the first marker doctors check because it's very sensitive to thyroid function changes.

What does high Reverse T3 mean?

High Reverse T3 can indicate your body is converting active thyroid hormone (T3) into an inactive form, which can happen during periods of chronic stress, illness, or severe calorie restriction. This can leave you feeling fatigued and experiencing hypothyroid symptoms even when your other thyroid numbers look normal. It's often a sign that your body is trying to conserve energy during times of stress.

How often should I retest my thyroid levels?

If you're starting or adjusting thyroid medication, your doctor will typically want to retest every 6-8 weeks until your levels stabilize. Once your thyroid function is stable, retesting every 6-12 months is common for ongoing monitoring. If you're testing for symptoms and results are borderline or you're making lifestyle changes, retesting in 3-6 months helps track whether your interventions are working.
