Some labs prefer an 8 to 12 hour fast. Many recommend avoiding high-dose vitamin C supplements beforehand. Follow the instructions provided with your lab order.
Where is the blood draw done and how long until results?
You receive a lab order after purchase. You can visit a partner lab such as Quest Diagnostics or LabCorp. Results usually arrive within a few days, depending on the lab.
