Q [Diagnostic Test] –[Blood Test] How many hours should I fast before the test?

You should usually fast for eight hours. Depending on the test, you may have to fast for about 12 hours. You can drink some water. In particular, the diabetes test and lipid test (cholesterol, triglyceride, etc.) have test items where you must observe the fasting time for accurate test results, and blood sugar is measured two hours after eating.

Also, the breath test requires a complete fast for 4 hours. Please follow the instructions before the test.

Q [Diagnostic Test] –[Blood Test] Why blood is drawn into many test tubes at the time of a blood test?

Since the required containers are different depending on the types of test, multiple containers can be used for blood sampling if there are many tests.
