VA No Longer Requires Fasting for Most Blood Tests

Why the change?

• Accurate blood test results can be obtained without overnight fasting for most blood tests.
• New research shows overnight fasting can cause low blood sugar. Especially for people with diabetes. 
• Low blood sugar can lead to accidents and other harmful events.
• After fasting all night, everyone wants a blood test first thing in the morning. No fasting means getting your blood tests anytime during normal clinic hours.

What is not changing?

• Some special blood tests still require fasting or not taking certain medicines.
• Your health care team will give you detailed instructions if you should not take your daily medicines or need to fast for a blood test.
