What blood lab tests require fasting?

Several blood lab tests require fasting to ensure accurate results, including fasting blood glucose tests, lipid panels (cholesterol and triglycerides), and certain liver function tests. Fasting typically means abstaining from all food and drink, except for water, for 8-12 hours prior to the test. It's important to follow specific guidelines provided by your healthcare provider, as the requirements may vary depending on the test. Always confirm fasting instructions before your appointment.
