Top Tips for Passing Your Phlebotomy Certification Exam
Getting certified as a phlebotomist is a big deal. It’s not just about finishing a course—it’s about proving you have what it takes to safely and confidently work in the field.
The good news? Most people pass the phlebotomy certification exam on their first try—if they’re prepared.
This guide will show you exactly how to study, what to expect on test day, and how to overcome nerves and pass with confidence.
What’s on the Phlebotomy Certification Exam?
The exam will vary slightly depending on the organization (NHA, ASCP, NCCT, etc.), but they all test the same essential knowledge and skills:
Common Exam Topics:
- Anatomy & physiology (especially circulatory system)
- Infection control and safety (OSHA standards)
- Specimen handling and transport
- Patient identification and communication
- Equipment use (needles, tubes, tourniquets)
- Legal/ethical guidelines (HIPAA, consent)
Test Format:
- 100 to 150 multiple-choice questions
- Time limit: 1.5 to 2.5 hours
- Computer-based testing at a certified testing center
Some exams (like ASCP) may also include questions about lab operations and more technical content.
Step 1: Know Which Exam You’re Taking
Your training program should guide you toward a specific certifying body. The most popular options are:
| Organization | Certification | Website |
|---|---|---|
| NHA | CPT | nhanow.com |
| ASCP | PBT | ascp.org |
| NCCT | NCPT | ncctinc.com |
| AMT | RPT | americanmedtech.org |
Each exam has a downloadable candidate handbook. Start there. Know what’s expected, the number of questions, test length, and what to bring.
Step 2: Create a 2–4 Week Study Plan
Don’t cram the night before. Instead, spread your study time out:
Week-by-Week Breakdown:
- Week 1: Anatomy, infection control, safety protocols
- Week 2: Specimen collection procedures and order of draw
- Week 3: Legal/ethical topics and review of weak areas
- Week 4: Practice exams, test-taking strategy, rest
Study 30–60 minutes a day, using breaks or flashcards to reinforce.
Step 3: Use the Right Study Materials
✅ Official study guides from your certifying body ✅ Flashcards for terminology and order of draw ✅ Online test banks like Union Test Prep or Quizlet ✅ YouTube tutorials (check out 4YourCNA and The Basic Nurse)
Ask your instructor if they have recommendations or past students’ tips.
Step 4: Master the Order of Draw
One of the most commonly tested—and failed—topics is order of draw.
| Tube Color | Additive | Tests |
| Yellow | SPS | Blood cultures |
| Light Blue | Sodium citrate | Coagulation (PT, PTT) |
| Red | None | Serum, chemistry |
| Gold/Tiger Top | SST | Chem panels, lipids |
| Green | Heparin | Stat chem, ammonia |
| Lavender | EDTA | CBC, hematology |
| Gray | Sodium fluoride | Glucose, alcohol |

Step 5: Practice Skills—Even at Home
If you’re still in training, ask your instructor if you can:
- Rehearse the steps for venipuncture out loud
- Practice labeling and transporting samples
- Use foam arms or oranges for needle technique
Even at home, you can:
- Write out each skill step by memory
- Record yourself explaining each skill
- Time yourself simulating a patient interaction
Confidence grows with repetition.
Step 6: Take Full-Length Practice Exams
Simulate the real exam environment:
- Find a quiet space
- Set a timer
- Don’t pause
- Review missed questions after
Do at least 2–3 full-length mock exams in the week before your test.
Step 7: Understand the Common Mistakes to Avoid
- Misreading “except” or “not” in questions
- Forgetting key pre-procedure steps (handwashing, ID check)
- Rushing through the order of draw
- Skipping over lab safety protocol
- Not managing your test time properly
Be strategic, not rushed.
Test Day Checklist
✔️ Get a good night’s sleep ✔️ Eat a balanced meal (skip the sugar crash) ✔️ Bring valid ID and test confirmation ✔️ Arrive at least 15 minutes early ✔️ Breathe, pause, and scan each question carefully
