Test Preparation
To ensure accurate results, follow these preparation guidelines:
- No fasting required; you can eat and drink normally.
- Wear loose, short-sleeved clothing to allow easy access to the arm.
- Avoid applying lotions, creams, or oils on the arm before the test.
- Inform your doctor if you have a history of vascular diseases, diabetes, or hypertension.
- Avoid smoking or caffeine for a few hours before the test, as they can affect blood flow.
