Low Blood Pressure

Hypotension itself is easy to diagnose. Taking your blood pressure is all you need to do. But figuring out why you have hypotension is another story. If you have symptoms, a healthcare provider will likely use a variety of tests to figure out why it’s happening and if there’s any danger to you because of it.

What tests will be done to diagnose low blood pressure?

Your provider may recommend the following tests:

Lab testing

Tests on your blood and pee (urine) can look for any potential problems, like:

• Diabetes.
• Vitamin deficiencies.
• Thyroid or hormone problems.
• Low iron levels (anemia).
• Pregnancy (for anyone who can become pregnant).

Imaging

If providers suspect a heart or lung problem is behind your hypotension, they’ll likely use imaging tests to see if they’re right. These tests include:

• X-rays.
• Computed tomography (CT) scans.
• Magnetic resonance imaging (MRI).
• Echocardiogram or similar ultrasound-based tests.

Diagnostic testing

These tests look for specific problems with your heart or other body systems.

• Electrocardiogram (ECG or EKG).
• Exercise stress testing.
• Tilt table test (can help in diagnosing orthostatic hypotension).
