Using the Active Stand Test to Assess Infection-Associated Chronic Conditions

Aug 5
The Active Stand Test (AST) is a simple yet insightful test that helps assess infection-associated chronic conditions. Whether you are a health professional, a patient, or a researcher, understanding the AST can offer valuable insights into patient health.

How to Conduct the Active Stand Test

The origins of the Active Stand Test can be traced back to early studies on orthostatic hypotension and syncope. Researchers sought a reliable method to evaluate cardiovascular function and autonomic responses to postural changes. Over time, the AST evolved, gaining validation through numerous studies and clinical trials.

Required Equipment

Performing the AST doesn't need much gear, so it can be done at the clinic or home. All that is required is a digital blood pressure monitor, a heart rate monitor, and a stopwatch. Just check that these tools are calibrated correctly to get accurate results.

Patient Positioning

Correct patient positioning is crucial for the test. The patient needs to lie on their back for about five minutes to establish initial measurements. After that, they should stand up fast and stay standing for at least three minutes while measurements are recorded.

Instructions for Conducting the Active Stand Test

  1. Measure and write down the patient's starting blood pressure and heart rate when they're lying down. 
  2. Then, ask the patient to stand up fast.
  3. Measure and write down the blood pressure and heart rate right after they stand up, and every minute for three minutes.
  4. Watch for big changes and any signs like feeling dizzy or lightheaded.

Integrating AST into Clinical Practice

For Health Professionals

The AST mainly checks how your heart and blood vessels react when you change positions. When you stand up, blood collects in your legs. Your body's automatic system then makes your heart beat faster and tightens blood vessels. If this reaction isn't normal, it might point to heart problems.

For Patients

Health experts can use the AST to check heart and nerve function in patients with long-term infections. It's simple and affordable, making it a great tool for diagnosing health issues.
