Do you have to fast for a basic metabolic panel?
Other blood tests that require fasting. People may be asked to fast for: Basic or comprehensive metabolic tests: Tests for blood sugar, electrolyte balance, and kidney function. Typically, people will be asked to fast for 10 to 12 hours before having one of these tests.
