Why do some people faint from having their blood drawn?
An involuntary reaction in the brain causes the blood pressure to drop temporarily. Outpatients are more likely to faint than inpatients because they are usually sitting up during the procedure. If you tend to get lightheaded from blood testing or you are already feeling weak from fasting or illness you should request to have your blood drawn while in a reclining position. This will help prevent or minimize fainting and avoid injury due to falling. Our staff will appreciate the communication.
