This test measures calcium that is biologically active. Calcium is essential for the healthy development and maintenance of teeth and bones. It is also a critical electrolyte, essential for the healthy function of muscles, nerves and blood clotting.
This blood test is used to measure Adrenocorticotropic Hormone (ACTH) levels. ACTH levels are measured to help identify and monitor health conditions related to excessive or deficient cortisol in the body. Adrenocorticotropic hormone is one of four major adrenal cortical hormones and is produced by the anterior lobe of the pituitary gland. Adrenocorticotropic hormone stimulates the secretion of cortisone and aldosterone. Cholesterol is required for the production of all adrenal cortical hormones. Testosterone, estrogen, cortisol and aldosterone are all adrenal cortical hormones.
