All Hormone and Adrenal Tests

The Selenium Micronutrient Blood Test measures selenium levels in the blood to assess nutritional status and detect deficiencies or excess. Selenium is a powerful antioxidant that supports thyroid function, immune defense, and protection against oxidative stress. This test helps identify dietary insufficiency, malabsorption, or toxicity, supporting diagnosis and management of overall health and wellness.

Patient must be 18 years of age or older.

Specimen Type: Blood

The Selenium Test measures selenium levels in blood to evaluate nutritional status and overall health. Selenium is essential for thyroid function, antioxidant defense, and immune support. Low levels may cause fatigue, muscle weakness, thyroid problems, or impaired immunity, while high levels may indicate toxicity. Doctors use this test to monitor nutrition, supplementation, or suspected deficiency. Results provide key insight into metabolic health and antioxidant balance.

Specimen Type: Serum

 The Selenium RBC test measures the level of selenium in red blood cells (RBCs). Selenium is an essential trace element that plays a crucial role in various bodily functions, including antioxidant defense, thyroid hormone metabolism, and immune function. The test provides valuable information about the body's selenium status over a more extended period compared to measuring selenium levels in plasma or serum.

Specimen Type: Blood

The Sex Hormone Binding Globulin (SHBG) Test measures SHBG, a protein that binds testosterone and estrogen, to assess how much active hormone is available in the body. Abnormal levels may indicate PCOS, infertility, low testosterone, liver disease, or thyroid disorders. Doctors order this test to investigate symptoms like low libido, irregular periods, acne, or hair loss and to evaluate hormone balance, endocrine function, and metabolic health in men and women.

Specimen Type: Serum

The Sodium test, also known as a serum sodium test, measures the concentration of sodium in the blood. Sodium is an essential electrolyte in the body, and this test helps assess the balance of sodium levels in the bloodstream. Sodium plays a critical role in maintaining proper fluid balance, nerve function, and muscle contractions.

Specimen Type: Varied

The T3 Uptake Test estimates thyroid hormone-binding capacity by measuring how well proteins in the blood bind triiodothyronine (T3). It does not measure T3 directly but helps assess thyroid function when combined with Total T4. Abnormal results may indicate hyperthyroidism, hypothyroidism, pregnancy, or protein-binding disorders. Doctors use this test to investigate fatigue, weight changes, or irregular heartbeat and to guide thyroid treatment decisions.

Specimen Type: Serum

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.

Specimen Type: Serum

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 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.

Specimen Type: Serum

The Testosterone Free and Total Test measures total testosterone and free, bioavailable testosterone in blood for both men and women. It helps diagnose hormone imbalance, infertility, low libido, erectile dysfunction in men, irregular periods, or PCOS in women. Doctors also order it to assess fatigue, mood changes, or muscle weakness and to monitor hormone therapy. This test provides key insight into reproductive, endocrine, and overall metabolic health.

Specimen Type: Serum

The Testosterone Free, Bioavailable, and Total Test measures total testosterone, free testosterone, and bioavailable testosterone, along with sex hormone binding globulin (SHBG) and albumin. This test provides a complete evaluation of hormone balance in men and women. Doctors use it to assess infertility, erectile dysfunction, low libido, PCOS, fatigue, or muscle loss and to monitor hormone therapy. Results offer key insight into reproductive, endocrine, and metabolic health.

Specimen Type: Serum

The Testosterone Free and Total and Sex Hormone Binding Globulin (SHBG) Test measures total testosterone, free testosterone, and SHBG to assess hormone balance in men and women. It helps diagnose infertility, erectile dysfunction, low libido, irregular periods, PCOS, and abnormal puberty. Doctors also use it to evaluate fatigue, muscle weakness, or mood changes and to monitor hormone therapy. This test provides a comprehensive view of reproductive, endocrine, and metabolic health.

The Testosterone Total Female Test measures testosterone levels in women to evaluate reproductive and endocrine health. Elevated testosterone may indicate PCOS, infertility, irregular periods, acne, or excess hair growth, while low levels may contribute to fatigue, mood changes, or low libido. Doctors order this test to diagnose hormonal imbalance, investigate symptoms, and monitor therapy. It provides key insight into hormone balance, fertility, and overall metabolic health.

Specimen Type: Serum

The Testosterone Total Male Test measures testosterone levels in men to assess reproductive, sexual, and hormonal health. It helps diagnose low testosterone (hypogonadism), infertility, and erectile dysfunction. Doctors use it to evaluate fatigue, muscle loss, or low libido and to monitor testosterone therapy, hormonal balance, bone health, and overall metabolism.

Patient must be male and 18 years of age or older.

Specimen Type: Serum

The Testosterone Total Test measures total testosterone levels in blood to evaluate reproductive, sexual, and endocrine health. In men, it helps diagnose hypogonadism, infertility, erectile dysfunction, or low libido. In women, abnormal levels may indicate PCOS or hormonal imbalance. Doctors use this test to investigate fatigue, muscle weakness, or mood changes and to monitor testosterone therapy. It provides key insight into hormone balance and metabolic health.

Specimen Type: Serum

Specimen Type: Blood

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.

Specimen Type: Serum

The Thyroid Panel Test measures Free T4 Index (T7), T3 Uptake, and Total T4 to evaluate thyroid hormone production and overall thyroid function. Abnormal results may indicate hypothyroidism, hyperthyroidism, or other endocrine disorders. Doctors use this test to investigate symptoms such as fatigue, weight changes, or irregular heartbeat and to monitor thyroid therapy. Results provide key insight into metabolism, energy balance, and endocrine health.

Specimen Type: Serum

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.
