Explanation:

Depends on if you asked for your blood type, which they will HAVE to draw your blood. Otherwise, any regular visit to the doctor will not require to draw your blood if it's a checkup. Though for certain visits/testing blood may be required to get drawn once- unless there is a problem during the drawing process. Hope this helped!
