How to Schedule and Prepare for a TriCore Lab Appointment

Scheduling a TriCore appointment depends on whether your doctor ordered the test or you're walking in

TriCore Diagnostics operates lab locations across New Mexico and parts of Texas. If your doctor ordered blood work or another lab test, you can schedule an appointment online through TriCore's website, by phone, or by walking into a location without an appointment — most TriCore labs accept walk-ins during their operating hours. If you're scheduling ahead, you'll need your insurance card and the lab order from your doctor's office.

Walk-in appointments typically have shorter wait times in the early morning, usually between 7 and 9 a.m. If you prefer a scheduled time slot, you can book online at tricore.org or call the specific lab location you plan to visit. When you call or book online, have your insurance information and your doctor's order number ready. TriCore will confirm what tests you need, what preparation is required, and how long the appointment usually takes.

If you don't have a doctor's order yet but need lab work done, you'll need to contact your primary care doctor or an urgent care clinic first. TriCore cannot order tests on its own — the order must come from a licensed healthcare provider.

Key Takeaways

• TriCore accepts both scheduled appointments and walk-ins at most locations, with walk-ins typically faster in early morning hours.
• You will need your insurance card and a lab order from your doctor to have tests performed at TriCore.
• Fasting requirements depend on which tests your doctor ordered, so confirm preparation instructions when you schedule or arrive.
• TriCore results are usually available within one to three business days and can be accessed through your doctor's patient portal or by calling the lab.

What to bring to your TriCore appointment

Bring your photo ID and insurance card to every TriCore appointment. If you have a printed lab order from your doctor, bring that as well — it shows the phlebotomist exactly which tests to perform. If your doctor sent the order electronically to TriCore, the lab will have it on file, but having a copy prevents delays if there's a mismatch in the system.

If you're a new patient at that TriCore location, arrive 10 to 15 minutes early to complete a brief intake form with your contact information and medical history. Returning patients can usually go straight to the draw station. Wear loose, short-sleeved clothing or clothing you can roll up easily — this makes it faster and more comfortable for the phlebotomist to access your arm.

Fasting and preparation before your test

Whether you need to fast depends entirely on which tests your doctor ordered. Blood glucose tests, lipid panels, and some metabolic panels require fasting for 8 to 12 hours before the draw — usually overnight. Other tests, like a complete blood count or thyroid panel, do not require fasting. When you schedule your appointment or when you arrive, ask the staff specifically whether fasting is needed for your tests.

If fasting is required, stop eating and drinking anything except water after midnight the night before your morning appointment. You can drink water up until the appointment. If you take regular medications, ask your doctor or the lab whether to take them on the morning of your test — some medications should be taken with food, while others may affect test results and should be held until after the draw.

For other types of tests — such as urinalysis or drug screening — TriCore staff will give you specific instructions when you arrive or when you schedule. Write down any instructions you're given so you don't forget them before your appointment.

What happens during a TriCore blood draw

When it's your turn, a phlebotomist will call you back to the draw station. They'll verify your name and date of birth, check your lab order, and ask you to sit in a comfortable chair with armrests. The phlebotomist will tie a soft band around your upper arm to make your veins more visible, clean the inside of your elbow with an alcohol wipe, and insert a needle to collect blood into one or more tubes.

The entire process usually takes 2 to 5 minutes. You may feel a brief pinch when the needle goes in, but it's not painful for most people. If you tend to feel faint or have a history of difficult draws, tell the phlebotomist before they start — they can have you lie back or take other precautions. Once the blood is collected, the phlebotomist will apply a bandage and you're done.

If your doctor ordered other tests — such as a urinalysis — TriCore staff will give you a cup and direct you to a restroom. These tests are straightforward and the staff will explain what's needed.

How long results take and where to find them

Most routine blood tests come back within 1 to 3 business days. More specialized tests may take longer — up to a week or more depending on what's being analyzed. TriCore will send results to your doctor's office, and your doctor's office will contact you with the results and what they mean.

You can also check results yourself if your doctor's office uses a patient portal — many do. Log into your patient portal and look for a "Lab Results" or "Test Results" section. If you don't have access to a patient portal, call your doctor's office and ask them to review the results with you over the phone. Do not call TriCore directly to ask about results — TriCore sends them to your doctor, and your doctor is responsible for explaining what the numbers mean and whether any follow-up is needed.

What to do if you need to reschedule or cancel

If you scheduled an appointment online and need to change it, log back into tricore.org and modify your appointment. If you scheduled by phone, call the same location back to reschedule. If you're a walk-in and realize you can't make it, there's no need to cancel — just don't show up, though arriving as early as possible on the day you plan to go will minimize your wait.

If you scheduled an appointment and realize you don't have your lab order yet, contact your doctor's office first. They can send the order to TriCore electronically, or you can pick up a printed copy and bring it with you. Don't cancel your appointment — just confirm with TriCore that the order has arrived before you go.

Common reasons TriCore appointments are delayed or rescheduled

If you arrive without a lab order, TriCore cannot perform any tests. Call your doctor's office from the lab and ask them to send the order electronically, or reschedule for another day when you have the order in hand. If your insurance information is incorrect or missing, TriCore may ask you to update it before drawing blood — bring your current card to avoid this.

If you were supposed to fast and didn't, tell the phlebotomist before the draw. Some tests can still be done, but others will need to be rescheduled. If you took medications that affect certain test results, mention that to the phlebotomist as well — they may note it on your lab slip so your doctor knows to interpret the results with that in mind.

Weather, traffic, or illness sometimes makes it impossible to keep an appointment. If you can't make it, reschedule as soon as you know. TriCore locations fill up, especially in the morning, so rescheduling early gives you more time options.

Frequently Asked Questions

Can I eat or drink before my TriCore appointment?

It depends on your tests. Fasting tests require no food or drink except water for 8 to 12 hours before the draw. Non-fasting tests allow you to eat and drink normally. Ask when you schedule or when you arrive which applies to you.

What if I'm nervous about needles?

Tell the phlebotomist before the draw starts. They can have you lie back, look away, or use other techniques to help you stay calm. Phlebotomists draw blood from nervous patients every day and know how to make it easier.

Do I need an appointment or can I just walk in?

Most TriCore locations accept walk-ins without an appointment. Walk-in wait times are usually shortest in early morning. If you prefer a scheduled time, you can book online or by phone to avoid waiting.

How do I know if my results are ready?

Your doctor's office will contact you, or you can check your doctor's patient portal if you have one. Results typically appear 1 to 3 business days after your test. Call your doctor's office if you don't hear back within a week.

What if TriCore doesn't accept my insurance?

TriCore works with most major insurance plans, but coverage varies. When you schedule, confirm that your insurance is accepted. If it's not, ask about self-pay rates or whether your doctor can order tests through a different lab that your insurance covers.
