What's this test for?

This test is ideal if you're experiencing unexplained fatigue, sudden weight gain or loss, mood swings, or feeling unusually cold or hot. It helps identify thyroid disorders that may be affecting your energy levels, metabolism, body temperature regulation, and overall well-being. Many people use this test when they suspect their symptoms are hormone-related but want concrete answers before seeing a specialist.

What happens after I get my results?

You'll get easy-to-understand doctor notes that explain your thyroid function and how it relates to symptoms like fatigue or weight changes. The notes provide actionable guidance on diet, supplements, or when to follow up with an endocrinologist. Along with your standard lab report, you can use our trends feature to monitor your thyroid levels over time, especially helpful if you're on medication or making lifestyle adjustments.

What's included in this test?

This panel measures Thyroid-Stimulating Hormone (TSH) and Thyroxine Free Direct Dialysis (FT4). This test measures TSH and Free T4, the two key markers that reveal how well your thyroid is functioning. TSH shows how hard your pituitary gland is working to stimulate your thyroid, while Free T4 measures the actual thyroid hormone available in your bloodstream. Together, these measurements help pinpoint whether your thyroid is underactive, overactive, or functioning normally, which directly impacts your energy, weight, mood, and metabolism.

How should I prepare for this test?

You should not have samples collected during or soon after receiving Heparin administration, as this can interfere with test accuracy. Otherwise, no special preparation like fasting is typically required for this thyroid test. Results are usually available within 7 business days, though additional time may be needed if confirmation testing is required.

When will I get my results?

Your results are typically available within 7 business days after your blood sample is collected. In some cases, if confirmation testing is required to verify findings, the turnaround time may be slightly extended. You'll receive an email notification as soon as your results are ready to view in your secure online account.

Who should consider getting this test?

This test is ideal for anyone experiencing unexplained fatigue, unexpected weight changes, hair loss, irregular periods, mood swings, or sensitivity to temperature. It's particularly important for women who are pregnant or trying to conceive, people with a family history of thyroid disease, and anyone already being treated for thyroid conditions who need regular monitoring. If you're feeling off but can't pinpoint why, checking your thyroid is a smart first step.

What symptoms indicate I may need this test?

Common symptoms of thyroid imbalance include persistent fatigue despite adequate sleep, unexplained weight gain or difficulty losing weight, feeling unusually cold or hot, dry skin and brittle hair, constipation, depression or anxiety, brain fog, and irregular menstrual cycles in women. You might also experience muscle weakness, a slower heart rate, or puffiness in your face. If several of these symptoms sound familiar, a thyroid test can help identify 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 7-8 hours of quality sleep, managing stress through yoga or meditation, and exercising regularly can help balance thyroid hormones naturally. Limiting processed foods, avoiding excessive raw cruciferous vegetables if you have thyroid issues, and maintaining a healthy weight also support optimal thyroid function.

What is TSH and why does it matter?

TSH (Thyroid-Stimulating Hormone) is produced by your pituitary gland and acts like a messenger that tells your thyroid how much hormone to produce. When TSH is high, it means your pituitary is working harder to stimulate an underactive thyroid. When TSH is low, it suggests your thyroid may be overactive and producing too much hormone. This biomarker is crucial because it's often the first indicator that your thyroid isn't functioning properly, even before you experience noticeable symptoms.

What does high TSH mean?

High TSH typically indicates hypothyroidism, meaning your thyroid gland is underactive and not producing enough thyroid hormone. Your pituitary responds by releasing more TSH to try to stimulate the thyroid. This can cause symptoms like fatigue, weight gain, feeling cold, dry skin, constipation, and depression. Common causes include autoimmune conditions like Hashimoto's thyroiditis, iodine deficiency, or thyroid damage from treatment or surgery.

How often should I retest my thyroid levels?

If you're being treated for a thyroid condition, your doctor will typically retest every 6-8 weeks after starting or adjusting medication until levels stabilize. Once stable on treatment, testing every 6-12 months is common for ongoing monitoring. If you're testing for diagnosis and results are normal but symptoms persist, your doctor may suggest retesting in 3-6 months, as thyroid function can change over time.
