How do I prepare for a mobile blood draw at home?

Preparing for a home blood draw is simple. Follow your doctor's specific instructions, and keep these general guidelines in mind:

Fasting (if required):

Many common tests (glucose, lipid panel, CMP) require fasting for 8–12 hours before the draw. Drink water during this time — staying hydrated makes veins easier to access. Avoid coffee, juice, and food.

Hydration:

Drink 16–32 oz of water before your appointment even if you are not fasting. Well-hydrated patients have more prominent veins and bleed more easily, reducing discomfort.

Medications:

Take your regular medications as prescribed unless your doctor specifically tells you to hold them. Always inform the phlebotomist of all medications, especially blood thinners (warfarin, aspirin, Eliquid).

Clothing:

Wear loose-fitting clothing with sleeves that roll up easily above the elbow. Short sleeves or a sleeveless top is ideal.

The draw space:

Choose a chair or location where you can sit comfortably with your arm extended and supported. Good lighting is helpful.

Have your lab order ready:

Have your doctor's lab requisition available (paper or electronic). The phlebotomist needs this to label specimens correctly.

ID:

Have a photo ID ready for identity verification.
