Which phlebotomy exam does Arizona use?
Arizona employers most often recognize the NHA Certified Phlebotomy Technician (CPT) and the ASCP Phlebotomy Technician (PBT). The exams are written and administered by those organizations, so the format is the same in every state.
Arizona does not issue a state phlebotomy credential. The Arizona Department of Health Services — Laboratory Licensure oversees laboratory testing under federal CLIA rules, and employers set their own certification requirements. Confirm with your employer and the state health department.
For a side-by-side comparison of the credentials, see our certification comparison. Most candidates pick the credential their target employer prefers; check job postings in Arizona before paying an exam fee.
Phlebotomy exam format
NHA CPT
The CPT has 100 scored questions plus 20 unscored pretest questions and a 2-hour time limit. NHA exams are multiple choice and can be taken at your school, at a PSI testing center, or through live remote proctoring. NHA scores on a scale of 200 to 500; passing is 390.
The CPT test plan weights five domains (items out of 100):
- Safety and Compliance: 26
- Patient Preparation: 20
- Routine Blood Collections: 28
- Special Collections: 12
- Processing: 14
ASCP PBT
The PBT has 80 multiple-choice questions in 2 hours, is computer adaptive, and is delivered at Pearson VUE testing centers. ASCP scores on a scale of 100 to 999; passing is 400. ASCP does not set a percentage of questions you must answer correctly.
ASCP's published content guideline lists these areas:
- Circulatory System: 5-10%
- Specimen Collection: 45-50%
- Specimen Handling, Transport, and Processing: 15-20%
- Waived and Point-of-Care Testing: 5-10%
- Non-Blood Specimens: 5-10%
- Laboratory Operations: 15-20%
Exam bodies revise their test plans. Always confirm the current format on NHA's CPT page or ASCP's PBT page before you register. Accommodations for documented disabilities are requested through the certifying organization.
Phlebotomy scope of practice and training in Arizona
Arizona does not issue a state phlebotomy credential. The Arizona Department of Health Services — Laboratory Licensure oversees laboratory testing under federal CLIA rules, and employers set their own certification requirements. Confirm with your employer and the state health department. The Arizona Department of Health Services — Laboratory Licensure is the state laboratory contact; federal CLIA rules also apply to laboratory testing.
Phlebotomy in Arizona is generally governed by employer requirements and federal CLIA rules rather than a state phlebotomy credential; only California, Louisiana, Nevada, and Washington issue state phlebotomy credentials. Confirm requirements with your employer and the state health department. NHA CPT and ASCP PBT are the most-recognized national credentials for phlebotomists working in Arizona.
Eligibility and training
Program length varies by school, and the exam bodies set eligibility rather than one national training-hours figure. For the NHA CPT, you need a high school diploma or equivalent, plus either a phlebotomy training program completed in the last 5 years or supervised work experience (1 year within the last 3, or 2 years within the last 5), and evidence of at least 30 venipunctures and 10 capillary or finger sticks on live individuals. For the ASCP PBT, ASCP lists several routes, for example a NAACLS-accredited phlebotomy program completed within the last 5 years, or 1 year of full-time clinical experience within the last 5 years.
See the NHA CPT page and the ASCP PBT page for the current eligibility pathways. To find a program in Arizona, check the Arizona Department of Health Services — Laboratory Licensure website at https://www.azdhs.gov/ or your local community college catalog.
How to apply for the phlebotomy exam in Arizona
Once your training program submits your completion to NHA or ASCP, follow these steps to register for the certification exam.
Step 1 — Create a candidate account
Go to https://www.nhanow.com (for NHA CPT) or https://www.ascp.org/boc (for ASCP PBT). Use the same legal name that appears on your government ID — your admission letter is matched against your ID at the testing center.
Step 2 — Verify your eligibility
NHA and ASCP verify your training or work experience through the documentation you submit. Follow each organization's instructions and contact your program director if your documents need to be sent by the school.
Step 3 — Choose a testing location
NHA exams can be taken at your school, at a PSI testing center, or by live remote proctoring. ASCP exams are delivered at Pearson VUE testing centers. Pick the option that works for you and schedule early.
Step 4 — Pay the exam fee
Fees are set by the certifying organization and change over time. ASCP lists a $155 non-refundable application fee for the PBT. NHA shows the CPT fee in your account at checkout. Some employers and training programs reimburse the fee; ask yours before paying out of pocket.
Step 5 — Schedule and confirm
Pick a date and time and keep your confirmation. If you need to reschedule, follow the certifying organization's policy (see the candidate handbook for deadlines).
Exam day checklist for Arizona phlebotomy candidates
The morning of your exam, give yourself plenty of time. Arrive early at a testing center (or log in early for remote proctoring) to allow for check-in and ID verification. Late arrivals may be turned away; check your provider's policy.
What to bring
- The government-issued photo ID your exam provider requires, with a name that matches your registration
- Your confirmation or admission information (printed or on your phone, if your provider asks for it)
- Anything else listed in your provider's instructions
What to leave at home
- Phones and other electronic devices, unless your provider says otherwise
- Notes, textbooks, or study guides
During the exam
The CPT gives you 2 hours for 100 scored questions plus 20 pretest questions, which averages about a minute per question. Read each question carefully and eliminate obviously wrong answers before choosing. Order-of-draw and additive identification are core collection topics on both exams.
Phlebotomy exam cost and fees
Exam fees are paid directly to the certifying organization and can change. ASCP lists a $155 non-refundable application fee for the PBT; NHA shows the CPT fee when you register at nhanow.com. Training tuition is separate and varies by school, so compare programs in Arizona and ask whether the exam fee is included.
Retakes: NHA requires a 30-day wait between attempts, allows three attempts and then a one-year wait, and charges the full price each time. ASCP allows up to five attempts under one eligibility route. Check each organization for current retake terms. Workforce Innovation and Opportunity Act (WIOA) funding may be available in some areas for eligible candidates; ask your local workforce office.
How to prepare for the Arizona phlebotomy exam
A reasonable plan is about 6-8 weeks of focused study after your training program (an editorial suggestion, not an exam requirement). Here is a study plan we recommend.
Week 1-2 — Review the content outline
Download the NHA CPT test plan or the ASCP PBT content guideline and read the content outline cover to cover. Make a checklist of the domains and start with the ones you feel weakest on.
Week 3-5 — Practice questions daily
Use the phlebotomy practice question bank to drill 30-50 multiple-choice questions per day. Read every explanation — even for questions you get right — so you understand the reasoning the certifying organization expects. Track your accuracy by topic and keep drilling your weakest areas before you schedule your exam. Practice scores are a study aid and do not predict an official result.
Week 6-7 — Skills rehearsal
Practice venipuncture, capillary puncture, and specimen handling out loud with a study partner. Narrate every step — order of draw, tube inversions, labeling, sharps disposal. If you have access to a lab or mannequin at your training program, book practice time.
Week 8 — Full-length simulations
Take at least two full-length timed simulations in our phlebotomy exam simulator to build test-day stamina.
