Can antibodies be elevated if my TSH is normal?

Yes! Antibodies often become elevated years before thyroid hormone levels change. This is why testing antibodies is so valuable - it can catch Hashimoto's early.

What does it mean if I have Hashimoto's?

Hashimoto's means your immune system is attacking your thyroid. It may lead to hypothyroidism over time. With monitoring and treatment if needed, most people manage well.

Is Hashimoto's hereditary?

Yes, there's a strong genetic component. If a parent or sibling has Hashimoto's or another autoimmune disease, your risk is higher. Testing can catch it early.

Should I test both TPO and TG antibodies?

Yes. While TPO antibodies are more common in Hashimoto's, some people only have elevated TG antibodies. Testing both provides the most complete picture.

Hashimoto's Panel - Autoimmune Thyroid Testing

The definitive panel for diagnosing Hashimoto's thyroiditis - the #1 cause of hypothyroidism. Tests both major thyroid antibodies that indicate autoimmune thyroid disease.

Hashimoto's thyroiditis is the most common cause of hypothyroidism, affecting up to 14 million Americans. This autoimmune condition causes your immune system to attack your thyroid gland, slowly destroying it.

This panel includes: • TSH - Detects thyroid dysfunction • Free T4 - Measures thyroid output • TPO Antibodies - Found in 90% of Hashimoto's cases • Thyroglobulin Antibodies - Second marker of autoimmune attack

Importantly, antibodies can be elevated years before thyroid hormone levels become abnormal - allowing for early detection and proactive management.

Included Tests

TSH (Thyroid Stimulating Hormone)

Measures thyroid-stimulating hormone to evaluate thyroid function. TSH is the most sensitive marker for detecting thyroid disorders.

TSH

Free T4 (Thyroxine)

Measures the unbound, active form of the thyroid hormone T4. Helps assess thyroid function and diagnose thyroid conditions.

Free T4

TPO Antibodies (Thyroid Peroxidase)

Detects antibodies against thyroid peroxidase enzyme. Elevated levels suggest autoimmune thyroid disease like Hashimoto's.

TPO Antibodies

$13.50

Thyroglobulin Antibodies

Detects antibodies against thyroglobulin protein. Used to evaluate autoimmune thyroid conditions.

Thyroglobulin Antibodies

$14.50

Free T3 (Triiodothyronine)

Measures the active thyroid hormone T3. Important for evaluating thyroid function, especially in hyperthyroidism.

What This Panel Measures

This panel measures thyroid function (TSH and Free T4) plus two antibodies that attack thyroid tissue. TPO antibodies target the enzyme that makes thyroid hormones. Thyroglobulin antibodies attack the protein used to produce thyroid hormones. Elevated antibodies confirm autoimmune thyroid disease.

Who Should Get This Panel

Anyone with unexplained thyroid symptoms, family history of Hashimoto's or autoimmune diseases, abnormal TSH results, or other autoimmune conditions. Essential for women planning pregnancy, as Hashimoto's increases miscarriage risk. Also important if thyroid issues run in your family.

When to Get Tested

No fasting required. Test anytime. Antibodies can be detected even when TSH is still normal, so don't wait for symptoms to worsen. If you have family history or other autoimmune conditions, test proactively.

Understanding Your Results

Elevated TPO antibodies (>35 IU/mL) and/or TG antibodies (>20 IU/mL) confirm Hashimoto's. Higher antibody levels often correlate with more thyroid inflammation. Even with elevated antibodies, thyroid hormone levels may still be normal initially.
