ASCP PBT exam format
Answer PBT-style phlebotomy questions from all six content areas of ASCP’s content guideline, read why each answer is right, then take a full timed exam at the real length and time.
The PBT(ASCP) exam has 80 questions in 2 hours. ASCP publishes a percentage range for each of six content areas rather than exact counts; Specimen Collection is almost half the exam. Our full practice exam is weighted inside those ranges and scores you by content area.
| Content area | Share of exam | What it covers | Drill |
|---|---|---|---|
| 1. Circulatory System | 5–10% | The heart, arteries, veins and capillaries; venous, capillary and arterial blood; plasma, serum and blood cells; terminology. | 10-question drill |
| 2. Specimen Collection | 45–50% | Orders, patient communication and identification, preparation, site selection, venipuncture and skin puncture technique, order of draw, complications and equipment. | 10-question drill |
| 3. Specimen Handling, Transport, and Processing | 15–20% | Specimen acceptability and add-on tests, accessioning and labeling, centrifuging and aliquoting, transport and storage by temperature, light and time. | 10-question drill |
| 4. Waived and Point-of-Care Testing | 5–10% | Urine dipsticks, hemoglobin and hematocrit, PT/INR, glucose and kit tests, instrument operation and troubleshooting, and internal and external controls. | 10-question drill |
| 5. Non-Blood Specimens | 5–10% | Urine, stool and sputum collection instructions, throat and nasopharyngeal swabs, breath tests, sweat chloride, chain of custody and specimen handling. | 10-question drill |
| 6. Laboratory Operations | 15–20% | Quality assurance and improvement, proficiency testing and competency, professional ethics and consent, laboratory and safety regulations, and infection control. | 10-question drill |

How our PBT practice exam differs from the real one
The real PBT is computer adaptive: each answer shapes which question comes next, every question must be answered before you move on, and the score is a scaled 400 or higher to pass. Our practice exam gives you 80 questions in 2 hours from all six content areas, with Specimen Collection at 37, Specimen Handling, Transport, and Processing at 14, Laboratory Operations at 13, Circulatory System at 6 and Point-of-Care Testing and Non-Blood Specimens at 5 each. It is a fixed set, so you can skip and return, and you get a raw score by content area rather than a scaled score.
Common questions
How many questions are on the ASCP phlebotomy exam?
80 multiple-choice questions in 2 hours. Each question has four options and one best answer. The exam is computer adaptive, so the questions you see depend on how you answer, and you cannot skip ahead.
What is on the PBT(ASCP) exam?
Six content areas from ASCP’s content guideline: Specimen Collection (45–50% of the exam), Specimen Handling, Transport, and Processing (15–20%), Laboratory Operations (15–20%), and Circulatory System, Waived and Point-of-Care Testing, and Non-Blood Specimens (5–10% each).
What score do you need to pass the ASCP PBT?
A scaled score of 400 on ASCP’s 100–999 scale. The scaled score is not a percentage of questions answered correctly. If you fail, your score report breaks the result down by content area.
How much does the ASCP phlebotomy exam cost?
The PBT(ASCP) application fee is $155 and is non-refundable. Each new attempt needs a new application and fee.
Is the ASCP phlebotomy exam hard?
Most candidates pass: 92% of the 1,506 PBT(ASCP) exams in 2025 were passes, and 93% of first-time takers passed. Repeat takers passed far less often, at 65%, so preparing well the first time matters.
How is the ASCP PBT different from the NHA CPT?
The PBT has 80 adaptive questions in 2 hours; the NHA CPT has 120 questions, 100 of them scored, in 2 hours. The PBT gives separate weight to the circulatory system, point-of-care testing, non-blood specimens and laboratory operations, so it reaches further into lab work than the CPT.
Does this practice test match the real PBT?
Our full practice exam has 80 questions in 2 hours, weighted inside ASCP’s ranges for each content area, with a score for each area and a worked explanation for every question. It is a fixed set of questions rather than an adaptive test, and it lets you skip and go back, which the real exam does not.
