True or false: will herbal tea affect blood tests? What you should know about it before drinking tea when you need to undergo a certain blood examination?
Will Herbal Tea Affect Blood Tests?
If you need to undergo certain blood tests as advised by your doctor, you may need to fast for 8 to 12 hours, depending on the instructions.

In some tests, stimulation of digestion enzymes can interfere with the results. In that case, you should avoid drinking herbal tea or other drinks as they can affect your blood tests.

It may affect your blood test. In that case, herbal tea is also a no-no.
However, if you’re fasting for a blood glucose exam, water may be okay but not herbal tea.

Preparation is the Key

However, other blood tests may not be affected if you drink herbal tea. Just remember that if the test requires fasting, it means that you can’t drink tea and other beverages. You also can’t eat anything.
If you have practiced intermittent fasting, fasting will be easier for you. You won’t get tired or anything because you’re used to not eating anything for a longer period.
