The PBT(ASCP) exam at a glance

The PBT(ASCP) exam is the phlebotomy technician certification exam of the American Society for Clinical Pathology Board of Certification (ASCP BOC), which earns the PBT(ASCP) credential (PBT(ASCPi) internationally). The BOC content guideline (revised September 25, 2025) gives 80 multiple-choice questions with one best answer in 2 hours, delivered as computer adaptive testing. Content areas are Specimen Collection 45 to 50%, Specimen Handling, Transport, and Processing 15 to 20%, Laboratory Operations 15 to 20%, and the Circulatory System, Waived and Point-of-Care Testing and Non-Blood Specimens 5 to 10% each. Regulatory questions are based on U.S. sources. The BOC reports a scaled score; guides say the scale is 100 to 999 with 400 to pass.

Updated November 2026 by the Tigertest team. Practice questions follow The ASCP BOC Phlebotomy Technician PBT(ASCP) and PBT(ASCPi) Examination Content Guideline (revised September 25, 2025), checked November 2026. Exam rules change, so confirm current details with ASCP BOC: PBT(ASCP) Examination Content Guideline.

How It Works

Train by Content Area

Four training sets follow the ASCP BOC content guideline: circulatory system, orders and site selection; order of draw and complications; specimen handling and point-of-care testing; and non-blood specimens and laboratory operations. Questions you miss come back until you have mastered them.

Weighted Practice Tests

Four fixed practice tests of 50 questions, each weighted like the content areas of the real exam. The real exam is computer adaptive; these are not. Aim for 70% or better. No question appears in more than one test, and every one comes with an explanation.

Built on the ASCP BOC Content Guideline

The BOC publishes a percentage range for each content area of its 80-question exam, and every practice test here stays inside those ranges, scaled to 50 questions: 23 on specimen collection, 8 each on specimen handling and laboratory operations, 4 each on point-of-care testing and non-blood specimens, and 3 on the circulatory system. Phlebotomy program instructors can set Tigertest as PBT review at tigertest.io/teach and see which topics the class misses most.

How to Pass the PBT(ASCP) Exam

1. Put specimen collection first

Specimen collection is about half the exam. Know patient identification, site selection, the CLSI order of draw for venous and capillary collections, what each tube additive does, common tests and their tubes, and how to handle fainting, hematomas, IVs and mastectomy.

2. Learn handling and shipping

Specimen handling is 15 to 20% of the exam. Review specimen acceptability and add-on tests, chain of custody, centrifuging and aliquoting, temperature and light needs, pneumatic tubes, and Category A and B shipping.

3. Do not skip lab operations

Laboratory operations is another 15 to 20%. Study quality control and proficiency testing, HIPAA and consent, CLIA and the agencies that regulate labs, the ABN, and OSHA and CDC rules on sharps, PPE and isolation.

4. Fix your misses, then retest

Tigertest tracks your accuracy by category. Aim for 70% or better on every practice test before your exam date. After each test, drill the questions you missed and retrain the weakest category.

PBT(ASCP) Exam Frequently Asked Questions

What is the PBT(ASCP) exam?

It is the phlebotomy technician certification exam of the American Society for Clinical Pathology Board of Certification (ASCP BOC). Passing it earns the PBT(ASCP) credential, or PBT(ASCPi) for the international version. Many candidates take it after a phlebotomy program or a period of work experience.

How many questions are on the PBT(ASCP) exam?

The BOC content guideline says the exam has 80 multiple-choice questions with one best answer, given in 2 hours. It is computer adaptive, so the questions each candidate sees depend on earlier answers. Tigertest models it as four fixed 50-question practice tests.

What score do you need to pass the PBT(ASCP) exam?

The ASCP BOC reports a scaled score rather than a percent correct; guides say the scale runs from 100 to 999 and 400 passes. The 70 percent line on these practice tests is a readiness target, not the official standard.

What is on the PBT(ASCP) exam?

Specimen collection is the largest content area at 45 to 50 percent: orders, patient identification and preparation, site selection, techniques, common tests, the order of draw, complications and equipment. Specimen handling, transport and processing and laboratory operations are 15 to 20 percent each, and the circulatory system, waived and point-of-care testing and non-blood specimens are 5 to 10 percent each. Each practice test here keeps that balance.

Are these the real PBT(ASCP) exam questions?

No. Every question is original, written by Tigertest from the ASCP BOC content guideline and from public standards such as the WHO guidelines on drawing blood, CLSI's published order of draw and OSHA and CDC rules. It covers the same knowledge without copying the exam. Tigertest is not affiliated with the American Society for Clinical Pathology.

I teach a phlebotomy program. Can my students use Tigertest?

Yes, for free. Make a class at tigertest.io/teach, post one link, and students join with just their name. You see who practiced, their test scores and the topics your class misses most.
