What to Expect at Your AdventHealth Lab Appointment

How AdventHealth Lab Appointments Work

AdventHealth lab appointments are scheduled visits to one of AdventHealth's laboratory locations to have blood drawn or other specimens collected for testing. You'll check in at the lab, provide your insurance card and ID, and a phlebotomist will draw your blood or collect whatever sample your doctor ordered. Most appointments take 10 to 15 minutes from check-in to leaving, though wait times vary by location and time of day.

AdventHealth operates lab locations across Florida, Colorado, Kansas, and other states where the health system has hospitals and clinics. You can schedule through your doctor's office, through the AdventHealth patient portal if you have one, or by calling the lab directly. Some locations accept walk-ins, but scheduling ahead usually means a shorter wait.

Key Takeaways

• Bring your insurance card, photo ID, and any lab order paperwork your doctor gave you or sent electronically.
• Some tests require fasting (no food or drink except water for 8 to 12 hours before), so ask your doctor or the lab when you schedule whether yours does.
• You can schedule through your doctor's office, the AdventHealth patient portal, or by calling the lab location directly.
• Most lab visits take 10 to 15 minutes, though arrival 5 to 10 minutes early helps with paperwork.

What to Bring and How to Prepare

Bring your insurance card and a photo ID (driver's license or passport). If your doctor's office gave you a lab order form or requisition, bring that too—it tells the lab exactly what tests to run. If your doctor sent the order electronically to the lab, you don't need the paper, but it doesn't hurt to have it.

Ask your doctor or call the lab before your appointment to find out whether you need to fast. Fasting means no food or drink except water, usually for 8 to 12 hours before the appointment. Common tests that require fasting include glucose tests, lipid panels, and some metabolic panels. If you're fasting, schedule your appointment in the morning when it's easier to avoid food overnight.

Wear loose, short-sleeved clothing or clothing with sleeves you can roll up easily. This makes it simpler for the phlebotomist to access your arm. If you tend to feel faint during blood draws, let the staff know when you check in—they can have you lie down or sit in a reclined chair.

How to Schedule Your AdventHealth Lab Appointment

The easiest way to schedule is through your doctor's office. When your doctor orders lab work, the office staff can often schedule the appointment for you right then and give you a time and location. This also ensures the lab order is already in the system when you arrive.

If you have an AdventHealth patient portal account (set up through your AdventHealth doctor or hospital), you can log in and schedule lab appointments directly. The portal shows available times at nearby locations and lets you pick the one that works for you.

You can also call the lab location directly. AdventHealth's main phone line can transfer you to the lab, or you can search online for "AdventHealth lab near me" to find the phone number for your nearest location. When you call, have your insurance information and doctor's name ready.

What Happens During Your Lab Visit

When you arrive, check in at the front desk. You'll give your name, insurance card, and photo ID. The staff will ask you to confirm your date of birth and address. If you're fasting, they may ask when you last ate or drank anything. They'll also ask if you've had any recent surgeries or if you're on blood thinners, since these can affect how the blood is drawn or processed.

You'll wait in the lab area until a phlebotomist calls your name. The phlebotomist will have you sit in a chair or lie on a bed, depending on the lab's setup. They'll tie a tourniquet (a soft band) around your upper arm to make the veins more visible, clean the inside of your elbow with an alcohol wipe, and insert a needle to draw blood into collection tubes. You'll feel a quick pinch, and the whole process usually takes less than a minute.

After the draw, the phlebotomist will apply a bandage or gauze and ask you to apply pressure for a minute or two. You can then leave. The lab will send your results to your doctor, usually within one to three business days, depending on the test. Your doctor will contact you with results or post them to your patient portal.

When You Might Need to Fast Before Your Test

Fasting is required for certain blood tests because food and drink can change the results. The most common fasting tests are lipid panels (cholesterol and triglycerides), glucose tests (blood sugar), and comprehensive metabolic panels. If your doctor ordered any of these, ask whether fasting is needed.

If fasting is required, stop eating and drinking (except water) at midnight the night before your morning appointment. You can drink water up until a few hours before the test. If your appointment is in the afternoon and fasting is required, your doctor will tell you when to stop eating—usually at least 8 to 12 hours before.

If you accidentally eat or drink before a fasting test, tell the lab staff when you check in. They may still draw your blood, but they'll note on your results that you weren't fasting, which helps your doctor interpret the numbers correctly.

What to Do If You Have Questions Before Your Appointment

Call your doctor's office if you're unsure what the lab work is for, whether you need to fast, or what to bring. They ordered the tests and can answer those questions quickly. If you have questions about the lab location, hours, or parking, call the AdventHealth lab directly.

If you're nervous about blood draws, let the staff know when you arrive. Phlebotomists are used to anxious patients and can help you feel more comfortable—they might have you lie down, look away, or take deep breaths during the draw. Some labs also have smaller needles or can draw from the back of your hand if your arm veins are difficult to access.

After Your Lab Appointment

You can usually go about your day normally after your appointment. If you were fasting, eat something soon after to bring your blood sugar back up. Drink extra water over the next few hours to help your body replace the fluid from the blood draw.

Some people feel lightheaded or have a small bruise at the needle site—both are normal and usually go away within a day or two. If you have unusual bleeding, severe bruising, or feel faint for more than a few minutes, contact your doctor.

Your results will be sent to your doctor, who will review them and contact you if anything needs follow-up. If you don't hear from your doctor within a few days, you can call their office to ask about your results, or check your patient portal if you have one set up.

Frequently Asked Questions

Can I eat or drink before my lab appointment if it's not a fasting test?

Yes. If your test doesn't require fasting, you can eat and drink normally before your appointment. However, avoid heavy meals right before—some people feel queasy during blood draws on a full stomach. A light meal or snack an hour or two before is fine.

What if I can't make my scheduled appointment?

Call the lab or your doctor's office as soon as you know you can't go. They can reschedule you for another time. If you don't show up without canceling, the lab may need to reorder your tests, which delays results and may require another appointment.

Do I need insurance to get lab work done at AdventHealth?

No, but bring your insurance card if you have one. If you don't have insurance, tell the lab staff when you check in. AdventHealth can discuss payment options with you, though costs vary by test and location.

How long does it take to get lab results back?

Most routine blood tests come back within one to three business days. Some tests take longer—your doctor will tell you what to expect. Results are usually sent to your doctor first, and your doctor will contact you or post them to your patient portal.

What if the phlebotomist can't find a vein?

Phlebotomists are trained to find veins in different locations if the usual spot doesn't work. They may try your other arm, the back of your hand, or a smaller needle. If they still have trouble after a couple of attempts, they'll let you know and may ask you to come back another time or refer you to a nurse who specializes in difficult draws.
