الإجابة: A. Morning serum cortisol and ACTH
Tuberculosis is the most common cause of primary adrenal insufficiency worldwide; orthostatic hypotension plus hyperpigmentation fits Addison's disease. The best test is morning serum cortisol and ACTH (low cortisol, high ACTH in primary disease). The aldosterone:renin ratio screens for hyperaldosteronism, not adrenal failure.

Cortisol is the initial test (low in adrenal insufficiency) and ACTH determines the cause (high in Addison disease, the primary form).

The aldosterone-to-renin ratio screens for excess aldosterone in primary hyperaldosteronism (high aldosterone, low renin), not for adrenal failure.

Hypoglycemia is only a general lab finding in adrenal insufficiency; the best initial test for hypocortisolism is a morning serum cortisol (or ACTH) level.
