Preparation for blood draws


  • Drink plenty of water (at least 8oz) the day before/day of blood draw (even if you are fasting)

  • No caffeine morning of blood draw (example: coffee, tea…etc)

  • No alcohol for 24 hours before blood draw

  • Drink 8 oz of water with a pinch of Himalayan salt at least 1 hour before blood draw

  • Try to avoid plane rides the day before/of blood draw

  • Ask what labs you will be having to determine if fasting or first morning urine is required

For patients with difficult veins consider the following:

  • Alka Seltzer gold: 1 packet in 8oz glass of water at least 1 hour before blood draw

  • Rehydration drops: 1 dropperful in 8oz glass of water 2 hours before blood draw

  • Using 1-2 lbs weights (or soup can) before the blood draw to help pump up the veins before the draw (this should be done at home)
