If you've never had lab work done on your own, the process can feel a little unfamiliar. Where do you go? What do you bring? How long does it take? The good news is that a lab visit is usually quick and simple. Most people are in and out in well under an hour, and the actual collection takes just a few minutes.

Here's a step-by-step look at what to expect, plus tips to make your visit easier.

Before Your Visit

Check Your Instructions

Some tests require fasting, usually 8 to 12 hours with only water. Others have no special prep at all. Check the instructions for your specific order before you go so you don't have to reschedule.

Know Where You're Going

Use the lab finder to choose a collection site near you and check its hours. Some locations take walk-ins, and others work better with an appointment. Early morning slots are popular, especially for fasting tests, so plan for a short wait.

Drink Water

Unless you've been told otherwise, drink a glass or two of water before your visit. Being well hydrated makes your veins easier to find, which can make the draw quicker and more comfortable. It also helps if your test requires a urine sample.

Dress for It

Wear a short-sleeved shirt or something with sleeves that roll up easily above the elbow. Bulky or tight sleeves make it harder for the collector to reach your arm.

What to Bring

• A valid photo ID. Most labs require it to confirm your identity.
• Your lab order or requisition. 
• A snack and drink. Especially helpful if you've been fasting.
• A list of your medications. Not always required, but handy if questions come up.

At the Lab

Check-In

When you arrive, you'll check in at the front desk. Staff will confirm your identity and your order. You may be asked to fill out a short form.

The Blood Draw

When it's your turn, a trained collector (often called a phlebotomist) will:

• Ask you to sit and extend your arm.
• Tie an elastic band around your upper arm to make the vein easier to see.
• Clean the area with an alcohol wipe.
• Insert a small needle, usually in the inside of your elbow, and fill one or more tubes.
• Remove the needle, apply pressure with gauze, and cover the spot with a bandage.

The needle part usually takes less than a minute. Most people feel a quick pinch and that's it. The number of tubes depends on your tests and doesn't mean more needles. All tubes are filled from the same draw.

Urine Samples

Some tests, including certain STD tests, use a urine sample. You'll get a sterile cup and instructions. For many STD urine tests, you'll be asked not to urinate for at least an hour before your sample, so the test has enough to work with. Check your instructions ahead of time.

If You're Nervous About Needles

You're not alone. A fear of needles is very common. A few things that help:

• Tell the collector. They work with nervous patients every day and can talk you through it.
• Lie down if you've ever felt faint. Ask if the lab has a reclining chair or bed.
• Look away. Focus on something across the room or on your phone.
• Breathe slowly. Slow, steady breaths can help keep you calm.
• Eat afterward. If you were fasting, have your snack as soon as your draw is done.

After Your Visit

Keep the bandage on for a few hours and avoid heavy lifting with that arm for the rest of the day. A small bruise is normal and fades in a few days. If you notice swelling, increasing pain, or bleeding that won't stop with pressure, contact a healthcare provider.

Then the waiting begins. Most routine tests come back within a few business days, though some take longer. Your results will be sent directly to you.
