The CPT exam, plainly.
The CPT from the National Healthcareer Association is the most common entry-level credential for U.S. phlebotomists. Most U.S. employers recognize it. The exam is designed to be passable in a focused 6-week study window.
If your school doesn't already point you at one specific certification, the CPT is recognized across most U.S. employers in phlebotomy.
The exam is administered by NHA · National Healthcareer Association. Full blueprint and registration are on the official site.
Cost, format, and scoring
The exam is computer-based and taken at a proctored testing center or via remote proctoring. You have 2 hr 10 min for 100 + 20 pretest.

What's on it
The content domains and their approximate weights:
A 6-week study plan
The plan below assumes 30–45 focused minutes per weekday plus longer weekend sessions for practice tests. Adjust on your own schedule, but don't compress past 4 weeks unless you already work in phlebotomy.
Anatomy & blood basics
Veins, arteries, blood components.
Patient preparation
ID verification, test requisitions.
Specimen collection
Order of draw, additive tubes by color. Most of your study time goes here.
Handling, safety, compliance
Centrifugation, transport temps, OSHA.
Practice tests
Three full-length practice exams. Review missed questions, not the ones you got right.
PhleboPrep offers adaptive practice questions matched to the NHA CPT blueprint.
After you pass
Most phlebotomy employers want to see your card on day one. Your CE cycle starts on issue, not on hire. We cover renewal logistics in the Phlebotomy career guide.
