"Classic Misunderstanding" About Blood Drawing

Pulished on Aug. 12, 2019

As a Serum Tube Factory, let's talk to you about the "classic misunderstanding" about blood drawing.

1. Can't drink water before taking blood?

You don't need to deliberately ban blood. You can drink a small amount of water in the morning and the night before. When you are thirsty, you can drink a few mouthfuls of water (50-100 ml) each time, as long as you don't drink a few hundred milliliters at a time. After all, the water is drunk and can be discharged through urination.

2. Will you lose blood when you draw blood?

When the blood is drawn, some women will ask the medical staff. Usually, the amount of menstruation will be more, the face will be pale, will blood draw more anemia, and need to "fill blood"? Experts explained that in fact, although the blood draw seems to pump a few tubes, each Blood Collection Tube is 3 to 5 ml, the general physical examination adds up to less than 20 ml. Normal human body has an average of 4000 ml of blood, and will automatically regenerate, do not have to eat anything to supplement, and soon will recover.
