Cushing’s Syndrome → Dexamethasone Suppression Test

  • Cushing’s Syndrome results from excess cortisol. The dexamethasone suppression test evaluates whether cortisol production is appropriately suppressed by exogenous steroids.

Addison’s Disease → ACTH Stimulation Test

  • Addison’s Disease involves adrenal insufficiency. The ACTH stimulation test checks if the adrenal glands can produce cortisol when stimulated.

Graves’ Disease → TSH Receptor Antibody Test

  • Graves’ Disease is an autoimmune hyperthyroid condition where autoantibodies stimulate the thyroid. The TSH receptor antibody test detects these autoantibodies.

Diabetes Insipidus → Water Deprivation Test

  • Diabetes Insipidus causes excessive urination due to ADH deficiency or resistance. The water deprivation test assesses the kidneys' ability to concentrate urine in response to dehydration.

Hashimoto’s Thyroiditis → Antithyroid Antibody Test

  • Hashimoto’s Thyroiditis is an autoimmune hypothyroid disorder characterized by elevated antithyroid antibodies.
