How should I prepare for my lab visit?

All instructions for your lab orders, including fasting, are included in your most recent Parsley Health visit note. You can access your notes in the “Health Plan” tab of your My Parsley Health profile. Your lab orders are available here.


If you need to make any changes to your lab order, please message your medical team at least 24 hours before your scheduled visit. Same-day changes can’t be guaranteed.


Before your blood draw:

  • Hydrate: Drink plenty of water the day before and the morning of your lab visit.
  • Fasting (if required): Do not eat or drink coffee or tea for 8–10 hours before your visit.
  • Medications: Continue prescription medications unless your provider tells you otherwise.
  • Exercise: Avoid intense exercise for 24 hours before your visit.

What to bring:

  • Photo ID and insurance card
  • Lab orders: Log in to your My Parsley portal to confirm your orders are visible. We recommend downloading or taking a screenshot of your order(s) so they’re accessible if the lab needs clarification.

After your blood draw:

  • If you feel dizzy or lightheaded, rest for a few minutes before leaving.
  • Have a snack and hydrate if you can.
  • Avoid strenuous exercise for at least 4 hours.
