Lab Smart = Live Strong

Getting labs is a normal part of life after having a transplant. Think of them as check‑ins that help make sure your transplanted organ is doing well and that your meds are working the way they should. As you take on more responsibility for your care, understanding why labs matter helps you stay on schedule for labs.

Now you know more about why labs are one of the best tools your transplant team uses to monitor the health of your transplanted organ.  Lab results can show how well your organ is working and can catch problems early—even before you feel something is “not right.”  They also help your team make sure your anti-rejection meds are at safe and effective levels. Labs can spot side effects from your meds, signs of infection, and other health changes. Overall, they give your team a clear picture of how you are doing—so they can keep you as healthy as possible. 

Here is more information on why labs matter. 

How Often Do You Need Labs?

The schedule is different for everyone, and it changes over time. How often you have labs depends on:

  • How long it’s been since your transplant (more labs early on, less often once things stabilize)
  • How well your transplanted organ is working
  • Recent lab results (if something is off, your team might repeat labs sooner)
  • Other factors (like if you recently had rejection treatment or your meds changed)

If you’re ever unsure, check with your transplant coordinator to confirm when your next labs are due.

Where Can You Go for Labs?

You can choose a lab anywhere that is convenient for you!  You can choose to go to a local lab close by your home or an outpatient lab at your local hospital.  The important thing is to make getting your labs easy and routine!

Most labs offer online scheduling or an app, which helps you:

  • Book appointments (even monthly recurring ones)
  • Get reminders
  • Check your results
  • Send messages to the lab

Before you go, make sure you have:

  • A photo ID: Your driver’s license or your school photo ID will work.
  • Insurance info: Bring your insurance card or have a photo of the front and back of the card in your phone.
  • Copay or payment method: The lab may ask for payment when you are there or will send you a bill. You can call ahead of time to see if a copay is needed.

Lab Orders: What You Need to Know

You will need a current lab order from your transplant team.

Pro tips:

  • Check with your coordinator to make sure there is a current order on file with your local lab.
  • Keep a paper copy or screenshot just in case the electronic version doesn’t go through.

What’s the best time of day to get my labs? 

Most labs can be drawn at any time, but medication levels and fasting tests have guidelines.

  • Fasting Labs: If you need fasting labs, your team will tell you.  Fasting means no food or drink except water for a certain amount of time.
  • Immunosuppression levels (tacrolimus, cyclosporine, sirolimus, mycophenolate): This blood test measures a trough level. This is the lowest “strength” of a medication in the blood. It helps your transplant team assess how effective the medication is in preventing rejection.  It also checks that this level stays within a range that is safe for you to decrease the risk of side effects. 
     
  • Trough levels are most accurate when you get labs
    • right before your next dose is due OR
    • at 10–12 hours after your last dose

Double‑check your lab instructions so your results are accurate. No one wants to make an extra trip to the lab!  Contact your transplant coordinator if you have any questions.

Looking Ahead

Labs will always be part of your transplant care — but the good news is they usually get less frequent as time goes on and you are in good health.  As you take more responsibility for your transplant care, it helps to:

  • Know your lab schedule
  • Use reminders or calendar alerts so you don’t miss your appointment
  • Go to lab appointments routinely and when asked
  • Stay in touch with your transplant coordinator to confirm lab requests and results

Building solid lab habits now helps you stay healthy and confident in managing your transplant healthcare into adulthood.
