Ordering the Hashimotos/Hypothyroid Panel | Thyroid Refresh
Ordering the Hashimotos/Hypothyroid Panel | Thyroid Refresh helps check for thyroid hormone levels and thyroid antibodies, which can show if your thyroid is working as it should. This test looks at T3, Free; T4, Free; Thyroid Peroxidase; and Thyroid Stimulating Hormone (TSH) to give a clear picture of thyroid function and possible autoimmune activity. Interestingly, thyroid antibodies can be present years before symptoms appear, making early detection possible even if you feel fine.
When ordering this panel, you get:
- Measurement of both T3, Free and T4, Free to see how much active thyroid hormone is available in your blood.
- Detection of thyroid peroxidase antibodies, which can point to autoimmune thyroid issues like Hashimoto’s disease.
- Assessment of TSH, which helps show if your thyroid is underactive or overactive.
- Ability to track changes in thyroid function over time for better management of symptoms.
- Information that can help your doctor adjust your treatment plan based on your specific thyroid hormone levels.
Who Should Consider Thyroid Function and Autoimmune Screening
People who feel tired all the time, have unexplained weight changes, or notice their hair thinning may benefit from this test. For example, someone who has been feeling unusually cold, gaining weight despite eating the same, and struggling with dry skin might find answers by checking their thyroid levels.
Ordering this panel may also be helpful if you:
- Have a family member with thyroid disease.
- Are experiencing changes in mood, such as feeling more anxious or down than usual.
- Notice swelling in your neck or a feeling of tightness around your throat.
- Are trying to get pregnant or have had trouble with fertility.
- Have high cholesterol that does not improve with diet or exercise, as thyroid issues can affect cholesterol levels.
Checking these markers can help you and your doctor find out if your symptoms are related to thyroid hormone changes or an autoimmune process, which can be measured and tracked over time. Delaying this test could mean missing early signs of thyroid problems, which may lead to more noticeable symptoms and make it harder to manage your condition later.
Preparing for Thyroid Hormone and Antibody Testing
Fasting is not needed before this blood test, so you can eat and drink as usual. Always follow any instructions your doctor or healthcare provider gives you to make sure your sample is collected correctly and your results are as useful as possible.
Labs Included When Ordering Your Hashimotos/Hypothyroid Panel | Thyroid Refresh
| Test Name | Reference Range | What This Biomarker Shows | Low and High Levels of This Marker |
|---|---|---|---|
| T3, Free | 2.3 – 4.2 | T3, Free measures the active form of triiodothyronine, a hormone that helps control how your body uses energy. It is important for metabolism, heart rate, and temperature regulation. |
High levels mean your thyroid may be overactive, which can cause symptoms like fast heartbeat or weight loss.
Low levels mean your thyroid may be underactive, which can lead to tiredness, weight gain, or feeling cold. |
| T4, Free | 0.8 – 1.8 | T4, Free shows the amount of unbound thyroxine in your blood, which is the main hormone made by the thyroid. It helps control how your body uses energy and supports many body functions. |
High levels mean your thyroid is making too much hormone, which can cause sweating, nervousness, or trouble sleeping.
Low levels mean your thyroid is not making enough hormone, which can cause tiredness, dry skin, or constipation. |
| Thyroid Peroxidase | 0 – 9 | Thyroid peroxidase antibodies are checked to see if your immune system is attacking your thyroid. High levels can point to autoimmune thyroid conditions like Hashimoto’s disease. |
High levels mean your body may be attacking your thyroid, which can lead to long-term thyroid problems.
Low levels mean there is little or no immune attack on your thyroid. |
| Thyroid Stimulating Hormone (TSH) | 0.40 – 4.50 | TSH is made by the pituitary gland and tells your thyroid how much hormone to make. It is the main signal for thyroid function and helps spot both underactive and overactive thyroid. |
High levels mean your thyroid may not be making enough hormone, which can cause tiredness or weight gain.
Low levels mean your thyroid may be making too much hormone, which can cause restlessness or weight loss. |
Reference ranges can change over time. For the most current values, visit the Quest Diagnostics lab test directory.
