Heading in for blood work? You might need to fast! Fasting before certain blood tests ensures accurate results, preventing skewed readings from recently consumed food and drinks. Typically, fasting involves abstaining from food and beverages (except water) for 8-12 hours before your appointment.
Why is it important? Food and sugary drinks can temporarily elevate glucose levels, cholesterol, and triglycerides. Fasting provides a baseline for these measurements, giving your doctor a clearer picture of your health.
What can you consume? Water is your best friend! Staying hydrated is crucial. Avoid sugary drinks, coffee, tea, and even sugar-free gum. Always confirm specific fasting guidelines with your doctor or the lab, as requirements vary depending on the tests ordered. Ignoring these instructions could lead to inaccurate results and potentially unnecessary further testing. Prepare ahead and make the fasting window as smooth as possible!
