ANGIOTENSIN II

The Angiotensin II test measures the concentration of angiotensin II — a key peptide hormone in the renin-angiotensin-aldosterone system (RAAS) — in plasma. Measured from a venous blood sample using sensitive immunoassay techniques, this test helps assess hormonal drivers of blood pressure, fluid balance, and vascular tone.

This assay is important for evaluating unexplained or resistant hypertension, suspected RAAS abnormalities, and for guiding treatment decisions involving ACE inhibitors, ARBs or other RAAS-targeting therapies. Results can assist nephrologists, cardiologists, and endocrinologists in diagnosing secondary causes of hypertension and tailoring patient-specific management plans.

Because angiotensin II levels are affected by posture, sodium status and concurrent medications, proper sample handling and clinical context are essential for interpretation. At-home venous collection across Dubai with Touch Connect ensures convenient sampling, certified laboratory analysis, and timely physician-ready reports — but always discuss any medication adjustments and result interpretation with your treating clinician.

• Angiotensin II (plasma)
• Sample type: EDTA plasma (venous blood)
• Reported units: pg/mL (or pmol/L)

• Resistant or difficult-to-control hypertension
• Suspected secondary hypertension (e.g., renal artery stenosis or endocrine causes)
• Hypertension with unexplained hypokalemia
• Before or during adjustment of RAAS-targeting medications
• Unexplained renal dysfunction or cardiovascular conditions where RAAS involvement is suspected

• Home venous sample collection across Dubai for patient convenience
• Analysis by accredited laboratories using sensitive immunoassays
• Actionable data to personalise antihypertensive and endocrine therapy
• Reduced clinic visits and private sample collection at your doorstep
• Clear, physician-ready reports with local clinical context for UAE providers

• At-home venous blood draw (EDTA plasma) performed by trained phlebotomist
• Morning collection preferred; rest quietly for 15–30 minutes prior to sampling
• Inform your physician about ACE inhibitors, ARBs, diuretics or other interfering medications — follow medical advice on temporary adjustments
• Avoid heavy exercise, smoking and large sodium intake before the test unless instructed otherwise
