DIAGNOSTIC TESTS

• Adrenocorticotropic hormone (ACTH)- function of the adrenal and pituitary glands
• Aldosterone - regulation of sodium blood levels

  • Catecholamines
  • Cortisol
• Diagnosis of hypoglycemia or diabetes mellitus:

  • Glucose
  • Glucose tolerance test (GTT)
  • Glycosylated hemoglobin (diabetes only)
• Growth hormone (GH) - function of the pituitary gland
• Insulin level - glucose metabolism and pancreatic function
• Parathyroid hormone (PTH) - function of the parathyroid
• Phosphorus (P) - diagnosis of endocrine disorders
• Testosterone - testicular function
• Thyroid function (T3, T4, TSH) studies - thyroid function
