Cholesterol Test Preparation Guide
Everything you need to know to prepare for an accurate cholesterol screening
Why Cholesterol Testing Matters
Regular cholesterol screening is crucial for maintaining heart health and preventing cardiovascular disease. High cholesterol typically has no symptoms, making blood tests the only way to detect potential issues early.
Heart Disease Prevention
High cholesterol is a major risk factor for heart disease, the leading cause of death worldwide. Early detection allows for timely intervention.
Stroke Risk Reduction
Elevated cholesterol levels contribute to plaque buildup in arteries, increasing the risk of stroke by up to 200%.
Track Treatment Effectiveness
Regular testing helps monitor how well lifestyle changes or medications are working to control cholesterol levels.
How to Prepare for Your Test
Fast for 9-12 Hours
Typically, you'll need to avoid all food and drinks except water for 9-12 hours before your test to ensure accurate triglyceride measurements.
Stay Hydrated
Drink plenty of water during your fasting period. Proper hydration makes blood collection easier and improves test accuracy.
Take Regular Medications
Continue taking prescription medications as directed unless your doctor specifically instructs you otherwise.
Heavy Meals Before Fasting
Avoid high-fat meals the evening before your test as they can temporarily elevate triglyceride levels.
Avoid alcohol and certain foods
At least 8 to 12 hours prior, avoid alcohol, sugary foods, simple carbs, and heavy or fatty meals as they can affect test results.
Strenuous Exercise
Vigorous physical activity before testing can temporarily alter cholesterol levels. Take it easy the day before your test.
