Can a Patient Have Liquids?
Fasting is not solely abstaining from food. When fasting, patients are often not permitted to drink any beverage aside from water. Although patients may perceive liquids to be different from food, they can still impact the test results’ credibility. For instance, drinking orange juice can influence one’s vitamin C levels, potentially producing false data. It is critical not to consume a beverage, such as orange juice, because the test results cannot distinguish whether someone’s enzymes are within normal range or were impacted by the beverage’s vitamins, minerals or sugar. Overall, people should avoid coffee, tea, soda, alcohol and juices before a blood test.
Keep in mind, it is important for patients to stay hydrated through drinking water as it makes blood drawing easier.
In addition to beverages, a patient should also avoid:
- Chewing gum
- Taking supplements and multivitamins
- Strenuous exercise
- Certain medications – Regarding drug use, make sure a patient has consulted with their doctor before fasting to see if they should take their medications. Most medications are usually fine but some may need to be avoided if they need to be taken with food.
