Exam Overview
The ASCP PBT (American Society for Clinical Pathology Phlebotomy Technician) exam is the gold standard in clinical phlebotomy. Hospital labs, reference laboratories, and pathology departments nationwide recognize and prefer ASCP certification. This credential demonstrates mastery of clinical phlebotomy with emphasis on pathology and specimen integrity.
The exam contains 100 questions that all count toward your score. You have 2.5 hours to complete the exam. Passing requires achieving 68% (68 of 100 questions), reflecting the exam's emphasis on clinical competency and deeper understanding.
Unlike entry-level exams, ASCP tests pathological context alongside procedure knowledge. You need to understand why certain techniques matter and how specimen quality directly impacts lab results.
Why Choose ASCP PBT?

Clinical Prerequisites & Eligibility
To be eligible for the ASCP PBT exam, you must meet these requirements:
Successful Collections
100 successful unaided blood collections (venipunctures and skin punctures on live individuals). On-the-job draws count toward this requirement.
Program Completion
Completion of a phlebotomy program (NAACLS-approved or equivalent). "Equivalent" can include on-the-job training. ASCP reviews each application individually. Contact ASCP directly at ascp.org/boc to confirm your eligibility.
Educational Requirements
High school diploma or equivalent
Already working in phlebotomy without a credential?
If you've been drawing blood on the job, your documented venipunctures count toward the 100-collection requirement. The "program completion" requirement can be satisfied by demonstrating equivalent on-the-job training. ASCP evaluates each applicant individually. Verify your eligibility directly at ascp.org/boc before purchasing any study materials.
