Do I need an appointment for a blood test in Colorado?

No. After you order you can walk in during the center’s hours, or book a time online at centers that offer it to skip the wait.

Do I need a doctor’s order?

No. An independent physician reviews and authorizes your order; it is covered by the order fee. Your lab order arrives by email.

How much does it cost?

You pay each test’s price plus one $18 fee per order, covering the blood draw and the physician order. Nothing is charged at the center.

A photo ID and your lab order (printed or on your phone). If a test needs fasting, skip food for the hours shown on your order.
