The Thyroid Function, Antibodies & Graves’ Comprehensive Lab Panel includes 10 tests and 11 biomarkers to support a deep review of thyroid function, thyroid signaling, hormone production, active thyroid hormone availability, thyroid conversion, thyroid binding, autoimmune thyroid patterns, Graves’-related TSI antibodies, and iodine status. Includes TSH, Free T4, Free T3, Reverse T3, Total T3, Total T4, TBG, TPO/Tg antibodies, TSI, and iodine.

The Thyroglobulin Panel Test measures thyroglobulin and thyroglobulin antibodies to evaluate thyroid function and monitor thyroid cancer. Elevated thyroglobulin may indicate thyroid tissue activity, while antibodies can interfere with results or suggest autoimmune thyroid disease. Doctors order this test after thyroidectomy, during cancer follow-up, or for suspected autoimmune disorders. Results provide insight into thyroid health, cancer monitoring, and treatment planning.

The Quantitative Thyroglobulin without Thyroglobulin Antibodies Test measures thyroglobulin levels in the blood to help monitor thyroid cancer treatment or recurrence. By excluding antibody interference, results are more accurate. Doctors use this test to track patients after thyroidectomy or radioactive iodine therapy and to assess thyroid tissue activity, ensuring precise monitoring and effective long-term management of thyroid cancer.

The Thyroglobulin Antibodies (TgAb) Test detects antibodies that attack thyroglobulin, a protein essential for thyroid hormone production. Elevated levels may indicate autoimmune thyroid disorders such as Hashimoto’s thyroiditis or Graves’ disease. Doctors order this test to evaluate symptoms like fatigue, weight changes, neck swelling, or irregular heartbeat and to confirm thyroid disease. It provides key insight into autoimmune activity and overall thyroid function.

The Thyroid Peroxidase and Thyroglobulin Antibodies Test measures TPO and TgAb antibodies that target thyroid enzymes and proteins essential for hormone production. High levels are linked to autoimmune thyroid disorders such as Hashimoto’s thyroiditis and Graves’ disease. Doctors order this test to evaluate fatigue, weight changes, neck swelling, or irregular heartbeat and to confirm thyroid autoimmunity. It provides vital insight into thyroid function and endocrine health.

The Thyroid Peroxidase Antibodies (TPOAb) Test detects antibodies that target thyroid peroxidase, an enzyme vital for thyroid hormone production. High levels often indicate autoimmune thyroid disorders such as Hashimoto’s thyroiditis or Graves’ disease. Doctors order this test to evaluate symptoms like fatigue, weight changes, hair loss, or irregular heartbeat and to confirm thyroid disease. It provides key insight into autoimmune activity and overall thyroid health.

The Pregnancy TSH Test measures thyroid-stimulating hormone levels to evaluate thyroid function during pregnancy. Abnormal TSH may indicate hypothyroidism or hyperthyroidism, conditions that can affect maternal health and fetal development. Doctors use this blood test to detect thyroid imbalances early, monitor treatment, and ensure proper hormone regulation, supporting a healthy pregnancy and reducing risks of complications for both mother and baby.

The T3 Free Test measures free triiodothyronine (T3), the active thyroid hormone not bound to proteins, to assess thyroid function. It helps diagnose hyperthyroidism, hypothyroidism, goiter, and pituitary disorders. Doctors order this test to evaluate symptoms like fatigue, weight changes, anxiety, or irregular heartbeat and to monitor thyroid replacement or antithyroid therapy. The Free T3 Test provides key insight into metabolism, energy regulation, and overall endocrine health.

The T3 Total Test measures total triiodothyronine (T3), a combination of both bound and unbound (free) T3, to assess thyroid function. Abnormal levels may indicate hyperthyroidism, hypothyroidism, goiter, or pituitary disorders. Doctors use this test to evaluate symptoms like fatigue, weight changes, anxiety, or irregular heartbeat and to monitor thyroid treatment. The T3 Total Test provides essential insight into metabolism, energy regulation, and overall endocrine health.

The T4 Free Test measures the level of free thyroxine (T4) in blood, the active thyroid hormone not bound to proteins. It helps diagnose thyroid disorders such as hypothyroidism, hyperthyroidism, and goiter, as well as pituitary conditions affecting hormone regulation. Doctors use this test to evaluate symptoms like fatigue, weight changes, hair loss, or irregular heartbeat and to monitor thyroid replacement or antithyroid therapy, providing insight into metabolic and endocrine health.

The T4 Total Test measures total thyroxine (T4) in blood, a combination of both bound and unbound (free) T4, to assess thyroid function. Abnormal levels may indicate hypothyroidism, hyperthyroidism, goiter, or pituitary disorders. Doctors use this test to evaluate symptoms like fatigue, weight changes, hair loss, or irregular heart rate and to monitor thyroid replacement or antithyroid therapy. The T4 Total Test provides key insight into metabolic, hormonal, and endocrine health.

The Thyroid Stimulating Hormone (TSH) Test measures TSH levels in blood to assess thyroid function and diagnose hypothyroidism or hyperthyroidism. It evaluates how the thyroid controls metabolism, energy, weight, and heart rate. Doctors use the TSH test to investigate symptoms such as fatigue, hair loss, or mood changes. Frequently included in routine health exams, it is also key for monitoring thyroid disease treatment and overall endocrine balance.

The TSH with Reflex to Free T4 Test first measures thyroid-stimulating hormone (TSH) to evaluate thyroid function. If TSH is abnormal, the test automatically measures Free T4, the active thyroid hormone, for more accurate diagnosis. Doctors use it to detect hypothyroidism, hyperthyroidism, or pituitary disorders and to investigate symptoms like fatigue, weight changes, or irregular heartbeat. It is also used to monitor thyroid therapy and overall endocrine health.
