Introduction
Check blood lipids after fasting for 8–10 hours. Avoid eating after 10 PM the previous night, as food intake can elevate blood lipid levels, especially triglycerides, affecting test accuracy. Additionally, maintain a normal diet for three days before the test to prevent alterations in your body's triglyceride levels that could lead to inaccurate results. Do not drink alcohol or engage in strenuous exercise prior to the test, as both may affect blood lipid concentrations.
Blood lipid tests require fasting for 8 to 10 hours.
Avoid eating after 10 p.m. the night before the test, and maintain an 8- to 10-hour fast. Eating can elevate blood lipid levels, especially triglycerides, which may affect test results. However, excessively prolonged fasting should also be avoided, as extreme hunger may trigger the release of stored body fat, leading to increased triglyceride levels and inaccurate test results.
In addition, maintain a normal diet for the three days prior to the test, focusing on light, easily digestible foods. Increase your intake of fresh vegetables and fruits, and avoid high-fat, greasy, and high-calorie foods, as these may alter triglyceride levels and lead to inaccurate test results. Alcohol should also be avoided before testing, as its high caloric content can interfere with results. On the day of the test, avoid strenuous exercise, which might affect lipid concentrations. It's recommended to rest quietly for 5 to 10 minutes before blood is drawn, allowing your body to fully settle, which helps ensure more accurate test results.
