Do I need to fast for a lipid panel?
In most cases, you need to fast for 10 to12 hours before your lipid panel blood test. Fasting means not eating or drinking anything except water. In some cases, getting a lipid panel test without fasting is possible.
In any case, it’s important to ask your healthcare provider in advance about whether you need to fast before the test. Always follow the instructions that your provider gives you. If your provider has instructed you to fast and you accidentally break the fast (eat), please let your provider know because the test is not as useful without fasting.
