Can I Drink Tea Before a Fasting Blood Test?

A fasting blood test, also known as a lipid profile or lipid panel, is one of the most common tests ordered by doctors. This test allows doctors to check cholesterol, triglycerides, and other blood levels. The test is done by taking a small sample of your blood and then analyzing it for certain components.

When preparing for a fasting blood test, you may be wondering if it is safe to drink tea before the test. The answer is, it depends. While drinking tea may not directly affect the results of the test, drinking tea may have other implications that should be taken into consideration.

Benefits of Drinking Tea

Drinking tea can be beneficial in some ways, especially if the tea is brewed naturally instead of with bags or instant mixes. Natural brewed teas are rich sources of antioxidants, and these antioxidants can help improve overall health.


Although there are benefits to drinking tea, there are some considerations as well if you are planning to take a fasting blood test. Here are a few things to keep in mind:

  • Calorie Content: Tea, especially when brewed naturally, typically contains calories. These calories can cause your blood sugar to rise, which may have an effect on the results of your test.
  • Caffeine: Depending on the type of tea and how it is brewed, tea may contain some caffeine. Caffeine is known to interact with certain tests and should be avoided when possible.
  • Other Ingredients: Herbal teas may contain other ingredients, such as herbs, fruits, or sweeteners that can also affect the results of a fasting blood test.


In conclusion, drinking tea before a fasting blood test may be acceptable, but it is always best to check with your doctor first. Some types of tea can affect blood sugar levels and interfere with the accuracy of the test. Be sure to talk to your doctor or medical practitioner to determine whether or not drinking tea can affect your results.
