Symptoms to Watch

Hypothyroidism (low thyroid)

Tiredness/weakness, cold intolerance, constipation, weight gain or difficulty losing weight, dry/rough skin, hair loss, puffy face/eyes, muscle aches or cramps, heavy or irregular periods, slowed thinking, low mood, and elevated cholesterol.

Hyperthyroidism (overactive thyroid)

Nervousness, tremor, irritability, racing heartbeat/palpitations, heat intolerance, sweating, increased appetite, more frequent bowel movements, thin/brittle hair, skin thinning, lighter/less frequent periods, and thyroid enlargement.

If these sound familiar, thyroid testing can help reveal the cause.

: Serum, Blood

 The TH-4 Thyroid Health panel represents the most comprehensive evaluation in the series, designed to assess thyroid function extensively, including thyroid hormone levels, autoimmunity, and specific markers indicative of autoimmune thyroid diseases. This panel is particularly valuable for diagnosing complex thyroid conditions and monitoring autoimmune thyroid disorders.
: Serum

TH-3. Thyroid Health Most Popular
 The TH-3 Thyroid Health panel is a comprehensive set of tests designed to provide an in-depth evaluation of thyroid function and autoimmunity. This panel assesses the levels of thyroid hormones, including the active and inactive forms, and checks for antibodies that indicate an autoimmune thyroid disorder.
: Serum

TH-2. Thyroid Health Most Popular
 The TH-2 Thyroid Health panel is a comprehensive set of tests designed to evaluate thyroid function more extensively than basic screenings. It includes assessments of both bound and unbound thyroid hormones, providing a detailed picture of thyroid activity and metabolism.
: Serum

TH-1. Thyroid Health Most Popular
 The TH-1 Thyroid Health panel is a basic yet essential set of tests focused on evaluating the primary aspects of thyroid function. This panel includes assessments for Free T4 and Thyroid Stimulating Hormone (TSH), providing a foundational understanding of thyroid health and activity.
: Serum

T4 Free Test Most Popular

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.

: Serum
Also Known As: Free T4 Test, Free Thyroxine Test, FT4 Test, T4F Test, Unbound T4 Test

TSH Test Most Popular

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.

: Serum
Also Known As: Thyroid Stimulating Hormone Test, Thyrotropin Test

T3 Free Test Most Popular

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.

: Serum
Also Known As: Free T3 Test, Free Triiodothyronine Test, FT3 Test, T3F Test, Unbound T3 Test

T4 Total Test Most Popular

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.

Also Known As: Total T4 Test, Total Thyroxine Test, T4 Test, Bound and Unbound T4 Test

T3 Total Test Most Popular

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.

Also Known As: Total T3 Test, Total Triiodothyronine Test, T3 Test, Bound and Unbound T3

T3 Reverse Test Most Popular

The T3 Reverse (rT3) Test measures reverse triiodothyronine, an inactive thyroid hormone, to assess thyroid and metabolic function. High rT3 may occur in hypothyroidism, chronic illness, stress, or during certain treatments, while low levels may reflect hormone imbalance. Doctors use this test along with TSH, Free T4, and Free T3 to evaluate fatigue, weight changes, or slow metabolism. The rT3 Test provides insight into thyroid regulation, energy balance, and endocrine health.

: Serum
Also Known As: Reverse T3 Test, RT3 Test, T3R Test

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.

Also Known As: Thyroid Antibodies Test, TPO and TgAb Test

TSI Test Most Popular

The Thyroid Stimulating Immunoglobulin (TSI) Test detects antibodies that stimulate the thyroid gland, often causing hyperthyroidism and Graves’ disease. High TSI levels may lead to symptoms such as weight loss, rapid heartbeat, or eye problems. Doctors order this test to confirm Graves’ disease, monitor treatment, or assess relapse risk. Results provide essential insight into autoimmune thyroid disorders and guide personalized management strategies.
