Angiotensin II: A specific radioimmunoassay for angiotensin ii showed that normal concentration in arterial blood is 2·4±1·2 (s.D.) mμg./l00 ml.; venous level is consistently below this value, usually 50–75% of it. Definite rises in blood angiotensin ii were found in some patients with hypertension, both essential and secondary to renal disease. Extremely low levels observed anephric state and conn's syndrome.
