Why test all these markers instead of just TSH?

TSH alone can miss many thyroid problems. You might have normal TSH but low T3, high Reverse T3, or elevated antibodies - all of which cause symptoms but won't show on a basic TSH test.

What is Reverse T3 and why does it matter?

Reverse T3 is an inactive form of T3 that blocks active T3 from working. High Reverse T3 (from stress, illness, or dieting) can cause hypothyroid symptoms even with normal TSH and T4.

Can this panel diagnose Hashimoto's?

Yes! The TPO and TG antibody tests are the key to diagnosing Hashimoto's thyroiditis. Elevated antibodies confirm autoimmune thyroid disease, even if thyroid hormone levels are still normal.

How much am I saving with this panel?

You save $6 compared to ordering these 5 tests individually. Plus, you get a complete picture in one blood draw instead of multiple tests.

Complete Thyroid Panel - Full Thyroid Assessment

Our most comprehensive thyroid panel includes all 5 essential markers: TSH, Free T4, Free T3, Reverse T3, and both thyroid antibodies. Get the complete picture of your thyroid health.

Unlike basic thyroid tests that only check TSH, this complete panel reveals the full story of your thyroid function. Many people with "normal" TSH still have thyroid issues that only show up with comprehensive testing.

This panel includes: • TSH - The pituitary's signal to your thyroid • Free T4 - The main hormone your thyroid produces • Free T3 - The active hormone your cells use • Reverse T3 - The "brake" form that blocks T3 • TPO & TG Antibodies - Autoimmune markers

Together, these markers reveal whether your thyroid is producing enough hormones AND whether your body is using them properly.

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

Free T3 (Triiodothyronine)

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

Free T3

$12

Reverse T3

Measures reverse T3, an inactive form of thyroid hormone. Elevated levels may indicate stress, illness, or conversion issues.

Reverse T3

$28

TPO & TG Antibodies

Comprehensive thyroid antibody panel testing both TPO and thyroglobulin antibodies for autoimmune thyroid assessment.

TPO AntibodiesThyroglobulin Antibodies

$27

What This Panel Measures

This panel measures the complete thyroid hormone pathway: TSH (pituitary signal), Free T4 (thyroid output), Free T3 (active hormone), Reverse T3 (inactive/blocking form), and both major thyroid antibodies (TPO and thyroglobulin) that indicate autoimmune thyroid disease.

Who Should Get This Panel

Anyone with unexplained fatigue, weight issues, hair loss, brain fog, or mood changes. Essential for those with family history of thyroid disease, abnormal TSH results, or anyone wanting a thorough thyroid evaluation. Also valuable for monitoring Hashimoto's disease.

When to Get Tested

No fasting required. Test anytime, but morning testing is often preferred for consistency. If on thyroid medication, test before your daily dose or at least 4 hours after.

Understanding Your Results

You'll receive results for all 5 markers with clear reference ranges. Look for: TSH 0.5-2.5, Free T4 1.0-1.5, Free T3 3.0-4.0, Reverse T3 ratio >10, and negative antibodies. Results outside these ranges warrant discussion with a healthcare provider.
