Hydrate the day before
Well-hydrated veins are easier to locate and less likely to collapse during collection. Water is best; avoid excessive caffeine if you are sensitive to dehydration.
Confirm fasting requirements
Some panels require 8 to 12 hours without food. Check your order instructions and plan your appointment for early morning when fasting is required.
Have paperwork ready
Keep your photo ID, insurance card, and any lab orders in one place before the phlebotomist arrives. This keeps the visit efficient and reduces repeat scheduling.
Wear comfortable clothing
Loose sleeves that roll above the elbow make access easier. If you use a mobility device, clear a path to a chair with arm support.
Share your health history
Let your collector know about prior difficult draws, allergies to adhesives, or medications that affect clotting. That information helps the team choose the best technique and supplies.
