Yes, fasting can significantly impact your cholesterol test results. Fasting for 9-12 hours before taking a cholesterol test allows for more accurate measurements of HDL, LDL, and triglyceride levels. This is because the absence of recent food intake ensures that the test measures these components accurately, reflecting your body's cholesterol levels without recent dietary influences.
