What to know before you go
Clinical lab tests are one of the most informative and least invasive ways to help your physician get a comprehensive view of your health. Still many patients are apprehensive about having their blood drawn. Being prepared can help alleviate the stress and improve the quality of your results.
To eat or not to eat?
Some tests require fasting. If your physician has requested that you fast prior to testing, you should refrain for eating or drinking anything except water for 8 to 12 hours before your blood is drawn. Be sure to drink enough water. Hydration is key to good health and improves your chances of an easy venipuncture. However, drinking other beverages, such as black coffee, tea, juice or other sugar-free beverages can interfere with your results.
Chewing gum, smoking and excessive excercise should also be avoided during the fasting period as these can affect your cholesterol, blood sugar and insulin levels.
Talk to your doctor about medication or supplements you are taking and whether it is appropriate or necessary to discontinue these prior to testing, as some of these can your lab results. For example, St. John’s Wort can reduce Digoxin levels. CoQ10, Ginkgo biloba and Fish Oil can interfere with the function of Coumadin.
