Possible Effects of Blood Collection

A routine blood draw is low risk. You may feel a brief sting when the needle goes in, and some people notice temporary bruising, soreness or light-headedness afterwards. Fainting and infection are uncommon. The sample is collected at your home by a trained phlebotomist using sterile equipment, and the draw takes only a few minutes. If you feel unwell during or after collection, tell the phlebotomist or speak to your doctor.
