Do you have to fast for euc blood test?

Yes, fasting is typically required for certain blood tests, including the lipid panel, which measures cholesterol and triglycerides. Fasting usually means not eating or drinking anything except water for 9 to 12 hours before the test. However, for other tests, such as a complete blood count (CBC) or basic metabolic panel, fasting may not be necessary. It's always best to follow your healthcare provider's specific instructions regarding fasting.
