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.

Week 1

Anatomy & blood basics

Veins, arteries, blood components.

Week 2

Patient preparation

ID verification, test requisitions.

Week 3–4

Specimen collection

Order of draw, additive tubes by color. Most of your study time goes here.

Week 5

Handling, safety, compliance

Centrifugation, transport temps, OSHA.

Week 6

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.
