Phlebotomy Practice Test

Pass your phlebotomy exam the first time. Phlebotomy Practice Test: CPT is a focused, offline study app for the NHA Certified Phlebotomy Technician exam — 500+ exam-style questions, a dedicated order-of-draw trainer, and timed mock exams built to the same domain weights as the real test plan. EVERY DOMAIN, ONE UNLOCK • Safety & Infection Control — bloodborne pathogens, PPE, sharps handling, exposure response • Order of Draw Trainer — tube sequence, additives, stopper colors, inversions • Routine Venipuncture — site selection, technique, complications, and what to do when a draw fails • Patient Preparation & ID — identification, consent, positioning, communication • Special Collections & Dermal Puncture — capillary technique, blood cultures, timed and pediatric draws • Specimen Handling & Processing — labeling, transport, centrifugation, rejection criteria THE ORDER OF DRAW, UNTIL IT IS AUTOMATIC It is the most cram-able thing on the exam and the easiest to lose under pressure, so it gets its own trainer: every tube in sequence, its additive, what that additive actually does, and how many inversions it takes. Every item is checked against one canonical sequence table, so the app can never teach you two different orders. TIMED MOCKS THAT MATCH THE REAL SHAPE 100 questions in 2 hours, sampled across the same five domains as the NHA CPT test plan and in the same proportions — so a weak area shows up in practice rather than on exam day. SMART REVIEW, NOT RE-READING Miss a question and it comes back tomorrow. Get it right repeatedly and it moves out of your way. A readiness score blends your deck mastery with your best mock, and an optional exam-date countdown paces the run-in. EVERY ANSWER EXPLAINED — AND CITED No bare answer keys. Every question carries a plain-English explanation and a citation to the official source it came from, so you can check anything you doubt. OFFLINE AND PRIVATE No account, no sign-in, no ads, no tracking. Everything runs on your device and your progress never leaves it. Study on a break, on the train, or with no signal at all. OFFICIAL SOURCES — THE COMPLETE LIST Every question in this app is derived from these sources and no others: • OSHA 29 CFR 1910.1030, Bloodborne Pathogens (eCFR): https://www.ecfr.gov/current/title-29/subtitle-B/chapter-XVII/part-1910/subpart-Z/section-1910.1030 • CDC, standard precautions: https://www.cdc.gov/infection-control/hcp/basics/standard-precautions.html • CDC (NIOSH), bloodborne infectious diseases: https://www.cdc.gov/niosh/healthcare/risk-factors/bloodborne-infectious-diseases.html • MedlinePlus lab tests (NLM): https://medlineplus.gov/lab-tests/ • NHA CPT test plan (structure + domain weights): https://www.nhanow.com/certifications/phlebotomy-technician • CLSI GP41 and GP42, the venous and capillary collection standards, cited by name: https://clsi.org/ Not affiliated with the National Healthcareer Association (NHA), ASCP, AMCA, NCCT, any certifying organization, or any government agency.

Practice scores are an estimate to help you judge your readiness. They are not an official result and do not guarantee a pass. NHA reports a scaled score rather than a raw percentage; this app grades the percent you got right and treats 75% as its own readiness benchmark.
