Enzyme Immunoassay (EIA)
Angiotensin I
FANGI
Hypertension
Plasma EDTA
Patient preparation: Patient should be on a normal sodium diet, 110 mEq of sodium. Patient should be in a recumbent posture for at least 30 minutes prior to collection of specimen. Diuretics, mineralocorticoids, glucocorticoids, estrogens, oral contraceptives, and ACTH medications and sodium, potassium, and posture all affect Angiotensin levels.
Specimen Type: Plasma
Collection Container/Tube: EDTA
Submission Container/Tube: Plastic vial
Specimen Volume: 3 mL
Collection Instructions:
Draw blood in a lavender-top (EDTA) tube(s).
Separate plasma from cells immediately after collection and send 3 mL of EDTA plasma frozen in plastic vial.
1 mL

Angiotensin I is a ten amino acid peptide formed by Renin cleavage of Angiotensinogen (Renin Substrate) I. Angiotensin I has little biological activity except that high levels cand stimulate Catecholamine production. It is metabolized to its biologically active byproduct Angiotensin II by Angiotensin Converting Enzyme (ACE). The formation of Angiotensin I is controlled by negative feedback of Angiotensin II and III on Renin release and by Aldosterone concentration. Levels of Angiotensin I are increased in many types of hypertension. Angiotensin I levels are used to determine Renin activity. Angiotensin I is excreted directly in the urine.
