Introduction

The Certified Phlebotomy Technician (CPT) credential is administered by the National Healthcareer Association (NHA). The CPT certification validates competency in venipuncture, capillary collection, specimen processing, and related administrative duties.

The NHA CPT exam consists of 120 questions (100 scored + 20 pretest) to be completed in 3 hours. The exam uses a computer-based format at PSI testing centers.

Test-Taking Tips

1. Order of draw is guaranteed to appear — Memorize it using a mnemonic (e.g., “Stops Blood Leaking, Give Lavender Gray”)
2. Know your tube colors and additives — This is one of the most heavily tested topics
3. Patient safety comes first — When in doubt, choose the safest answer
4. Read questions carefully — Look for keywords like “first,” “best,” “most appropriate,” “avoid”
5. Eliminate wrong answers — Usually 2 of 4 options can be eliminated
6. Know the adverse reactions — Hematoma, nerve injury, fainting, infection — causes and prevention
7. Two identifiers for patient ID — Name + DOB or Name + MRN; never use room number
8. Label at the bedside — Never pre-label tubes; label immediately after collection
9. Don’t recap needles — This is an OSHA violation and a common test question
10. Manage your time — 3 hours for 100 scored questions = 1.8 minutes per question
