What are the possible risks of having a blood test?
Phlebotomy, or drawing blood, is a secure procedure.

Possibilities of risk include:
Bleeding and bruising, which are avoided by pressing firmly after the needle is removed
Pain, which is typically minor and might continue for several minutes
Ask your nurse, doctor, or phlebotomist to avoid taking a blood sample from an arm that is swollen or in danger of edema (swelling)
If you ever feel dizzy, alert the person taking your blood
Infection (this is relatively uncommon).
