Description

The Thyroid Advanced Blood Panel provides a comprehensive evaluation of thyroid hormone balance, thyroid conversion, and autoimmune thyroid activity. This panel is designed to help identify common thyroid conditions such as hypothyroidism, hyperthyroidism, Hashimoto’s thyroiditis, and Graves’ disease.

Because the thyroid plays a critical role in metabolism, energy production, mood, heart rate, temperature regulation, and overall wellness, identifying imbalances early may help support more targeted treatment and long-term health management.

What’s Included in This Panel

TSH (Thyroid Stimulating Hormone)

Function: Regulates thyroid hormone production. Insight: Elevated levels may suggest an underactive thyroid, while low levels may indicate overactive thyroid function.

Free T3 (Free Triiodothyronine)

Function: Measures the active thyroid hormone used by the body’s cells. Insight: Helps evaluate metabolism, energy production, and thyroid hormone activity at the cellular level.

Free T4 (Free Thyroxine)

Function: Measures the primary hormone produced by the thyroid gland. Insight: Assesses available thyroid hormone circulating in the bloodstream.

Total T3

Function: Measures the total amount of T3 hormone in circulation. Insight: Provides additional evaluation of thyroid hormone production and conversion.

Total T4

Function: Measures the total amount of thyroxine hormone in the bloodstream. Insight: Helps evaluate overall thyroid hormone production and thyroid-binding protein activity.

Reverse T3 (rT3)

Function: Measures an inactive form of T3 that may interfere with normal thyroid hormone activity. Insight: Elevated levels may be associated with stress, inflammation, chronic illness, or impaired thyroid hormone conversion.

Thyroid Peroxidase Antibodies (TPOAb)

Function: Detects antibodies associated with autoimmune thyroid disease. Insight: Elevated levels are commonly associated with Hashimoto’s thyroiditis and may also be seen in Graves’ disease.

Thyroglobulin Antibodies (TgAb)

Function: Measures antibodies directed against thyroglobulin. Insight: May indicate autoimmune thyroid dysfunction and can support thyroid autoimmunity assessment.

TSH Receptor Antibodies (TRAb)

Function: Detects antibodies that stimulate or interfere with thyroid receptor activity. Insight: Commonly associated with Graves’ disease and hyperthyroidism.

Why This Test Matters

  • Evaluates thyroid hormone production, conversion, and activity
  • Detects autoimmune thyroid conditions
  • Helps identify thyroid imbalances that may not appear on basic screening panels
  • Supports evaluation of fatigue, brain fog, weight changes, hair thinning, anxiety, temperature sensitivity, and metabolic concerns
  • Provides a more complete picture of thyroid and immune function

Test Information

Fasting Required: No Sample Type: Blood draw

Recommended For

  • Individuals with symptoms of thyroid imbalance
  • Those with a personal or family history of thyroid or autoimmune disease
  • Patients monitoring thyroid treatment or thyroid medication
  • Anyone seeking a more comprehensive thyroid evaluation

Take a proactive approach to your thyroid health with advanced testing designed to provide deeper insight into hormone balance and thyroid function.
