Phlebotomy exam prep with answers you can check.
Explanations cite CLSI, OSHA and CDC references you can open and read, and practice drills what you get wrong. Two ways to pay: the Exam Pass is $30 for your first 3 months, or pay $15/month.
A failed NHA, ASCP or AMT attempt costs another exam fee and a 30–45 day wait before you can retest.

How PhlebBot is different
Three things students say go wrong with phlebotomy practice banks, and what PhlebBot does instead.
The complaint: The practice questions were nothing like the real exam.
Scenario questions, weighted to your exam
After a short recall baseline, practice moves to “what would you do if…” clinical scenarios, and every topic is weighted to the NHA CPT, ASCP PBT or AMT RPT blueprint you choose, so safety and patient care get the share of your time the exam gives them.
The complaint: Two apps give two different answers, and nobody says which one is right.
Explanations that show their source
Explanations cite the CLSI, OSHA or CDC reference passage they draw on, and you can open that passage in the reference library. When no reference is found, the reply is flagged as unverified instead of sounding sure.
The complaint: Once the practice test is submitted, the questions you missed are gone.
What you miss comes back
Miss a concept and it returns as a new question a few items later, then again on later study days, until you answer it right. Your history is saved across sessions.
Who built PhlebBot
Benjamin Tibbs
Creator & developer
“While training in phlebotomy, I noticed a gap between how students are taught and what actually determines success in real clinical settings.”
An operations and analytics professional with over a decade of experience building systems that reduce error, he built PhlebBot to give students structured practice thinking through real scenarios, with answers that cite their references.
What a training session looks like
Your instructor asks, you answer, and every mistake gets an explanation and a reference.
Orders: CBC, PT/INR, and a basic metabolic panel. You have a lavender, a light blue, and a gold SST on the tray. Which tube do you fill first?
Lavender, the CBC is the most important test.
Not quite. Light blue first. The coagulation tube is drawn before serum and EDTA tubes so additive carry-over cannot alter the PT/INR. Here the order is light blue, then gold SST, then lavender.
Reference: CLSI PRE02-Ed8, order of draw
Order of draw is now marked as a weak spot. It comes back in later sessions until you show you have it.

Common questions
Is it a subscription?
Yes, and here is exactly how it renews. Monthly is $15 each month until you cancel. The Exam Pass is $30 for your first 3 months; we email you 7 days before it renews at $15/month, so it never renews without notice. To cancel, open Settings and click Cancel subscription, then Yes, cancel: 2 clicks, no phone call, no form. You are not charged again, and you keep access until the end of the period you paid for.
How does billing work?
Choose the Exam Pass ($30 for your first 3 months, then $15/month) or Monthly ($15/month). You pay at checkout and get full access right away. We email you 7 days before an Exam Pass switches to monthly. Cancel from Settings → Cancel subscription at any time; access continues until the end of the period you paid for.
What is the Exam Pass?
One payment of $30 covers your first 3 months, which works out to $10/month. If your exam is within 3 months, it costs less than paying monthly, and far less than a retake: every NHA, ASCP or AMT retake means another exam fee and a 30–45 day wait. If you still need PhlebBot afterwards it continues at $15/month; if you passed, cancel in Settings and you are not charged again. The Exam Pass is for your first purchase.
What if my exam is in 2 weeks?
Choose Monthly. $15 covers your first month, which is cheaper than the Exam Pass when you only need a few weeks; the Exam Pass ($30 for 3 months) saves money only if you study for more than two months. With two weeks left, focus matters more than coverage: PhlebBot shows your readiness in every domain of your exam, so you can spend the time on the domains where you are weakest. The included AI gives you up to 60 tutoring turns a day. After your exam, cancel in Settings (2 clicks) and you are not charged again.
What do I get?
Adaptive training sessions weighted to your target certification exam, readiness tracking across every exam domain, a 4-phase training loop that adapts to your level, and explanations that cite references from CLSI, OSHA, and CDC. Think of it as a tutor that remembers what you got wrong.
Which exams does PhlebBot cover?
Three phlebotomy certification exams: the NHA CPT (Certified Phlebotomy Technician), the ASCP PBT (Phlebotomy Technician) and the AMT RPT (Registered Phlebotomy Technician). You choose your target exam, and practice and readiness are weighted to that exam's blueprint. PhlebBot does not cover the NCCT NCPT or AMCA exams.
Is the AI included, or do I need my own key?
Included. PhlebBot Pro runs the instructor on Google Gemini using our key, with up to 60 tutoring turns a day, so you can start the moment checkout completes. If you want unlimited turns or prefer OpenAI, Anthropic, DeepSeek, or Groq, you can connect your own API key in Settings; that provider then bills you directly for usage, typically $1–5 a month.
Do I need to be tech-savvy?
No. Sign in, subscribe, and begin: it is a conversation. Your instructor asks questions, you answer, and it teaches you. Nothing to install and no key to set up unless you choose to use your own.
Can I cancel anytime? What happens to my progress?
Yes. Cancel from Settings → Cancel subscription with no fees. Access continues until the end of the period you paid for, and your learning progress is saved if you come back.
How is this different from flashcards or question banks?
Flashcards and fixed question banks show everyone the same questions and only give you a score. PhlebBot tracks your readiness in every domain of your exam, weights practice to match the real blueprint, explains why an answer is right with a reference, and keeps returning to what you missed.
How does PhlebBot compare?
Other products are stronger in some ways, and we say so. Pocket Prep has native iOS and Android apps and a large fixed question bank. Several competitors sell one-time passes that do not renew, and some offer a refund window or a guarantee; PhlebBot offers neither. PhlebBot's difference is a conversational tutor for the NHA CPT, ASCP PBT and AMT RPT that keeps returning to what you missed and shows references when it finds one. Our comparison pages put the details side by side, with a link to each competitor's own page and the date we checked it.
