Blood tests are one of the most common and important medical tests. Doctors rely on blood test reports to understand what is happening inside our body and to decide the right treatment.

Let us gently understand the 7 most common mistakes people make before their blood test, so that you can get accurate results and peace of mind.

One of the biggest mistakes people make before their blood test is not fasting properly.

require you to fast for 8–12 hours.

Drink only plain water during fasting.
Avoid tea, coffee, milk, juice, or chewing gum.

2. Drinking Tea, Coffee, or Alcohol Before the Test
Another common mistake people make before their blood test is consuming beverages that affect the body.
Tea and coffee can raise blood sugar and affect hormone levels.
