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 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 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.

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.

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 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.

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.

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.
