What is this test?
The Angiotensin (1-7) test measures the amount of a specific hormone in your blood called Angiotensin (1-7). This hormone is part of the renin-angiotensin system, which helps control blood pressure, fluid balance, and heart function. Unlike other hormones in this system that can narrow blood vessels, Angiotensin (1-7) helps blood vessels relax and has protective effects on the heart and kidneys.
Why is it important?
Angiotensin (1-7) plays a crucial role in counterbalancing the effects of other hormones that can raise blood pressure. It helps reduce inflammation, prevents tissue scarring, and supports healthy blood vessel function. Doctors may order this test to better understand certain heart conditions, kidney diseases, or to assess how the body responds to treatments that affect the renin-angiotensin system.
How is the test performed?
A healthcare professional will draw a small blood sample from a vein in your arm. The blood is collected into a special tube and sent to a laboratory for analysis. You may need to fast (not eat or drink) for a certain period before the test, as directed by your doctor. The procedure is quick and generally causes minimal discomfort.
Reference range
Reference values are laboratory-specific and method-dependent; consult the performing laboratory's reference range. Typical reported values in healthy adults generally range from approximately 15-65 pg/mL when measured by LC-MS/MS.N/A
No special patient preparation is generally required. However, patients should maintain normal sodium intake prior to collection. ACE inhibitors, ARBs, and other RAAS-modifying medications may affect Angiotensin (1-7) levels; document recent medication use. Avoid strenuous exercise prior to collection.
