What is ASCP certification and which credential do I need?
The American Society for Clinical Pathology Board of Certification is the principal certifying body for clinical laboratory professionals in the United States. It does not award a single credential: it certifies across the whole laboratory ladder, including phlebotomy technicians, medical laboratory technicians at the associate-degree level, medical laboratory scientists at the baccalaureate level, histotechnicians and histotechnologists, cytotechnologists, and a range of technologist and specialist categories in disciplines such as blood banking, chemistry, microbiology, haematology, molecular biology and cytometry. Each credential has its own published eligibility routes combining education, completion of an accredited programme and documented laboratory experience. Examinations are computer adaptive. Certifications are maintained on a three-year cycle through the Credential Maintenance Program, and several states separately license laboratory personnel by reference to national certification.
- ASCP's Board of Certification certifies the entire clinical laboratory ladder, not one credential.
- Each credential has its own eligibility routes combining education, accredited programmes and documented experience.
- All examinations are computer adaptive, so exam length varies and says nothing about the outcome.
- Credentials are maintained on a three-year cycle through the Credential Maintenance Program.

ASCP Examination Format and Eligibility Routes
One board, many credentials, many routes
The Board of Certification publishes separate eligibility routes for each credential, generally combining a degree, completion of an accredited programme, and documented clinical laboratory experience in the relevant discipline. More than one route usually exists — an accredited-programme route for new graduates and an experience route for people already working. All examinations are computer adaptive, resolving your standing against a fixed passing standard rather than ranking you against other candidates.
Where the credentials sit
How does ASCP certification shape a laboratory career?
Because the board certifies at every rung, movement up the laboratory ladder is movement between credentials and between occupations — technician to scientist to specialist — rather than a premium on a single job.

What ASCP Examinations Cover, Laboratory Disciplines
Clinical Chemistry
Analyte methodology, instrumentation, interference and the quality control that decides whether a result may be released — plus the delta checks and critical values that trigger action.
Haematology
Cell morphology, automated differentials and flagging, coagulation testing and the abnormalities that require a manual review before reporting.
Transfusion Medicine
ABO and Rh typing, antibody screening and identification, crossmatching and component selection — the discipline with the least tolerance for procedural shortcuts.
Microbiology
Specimen adequacy, culture and identification workflows, susceptibility testing and the interpretive reporting that shapes antimicrobial prescribing.
Molecular Diagnostics
Amplification and detection methods, contamination control, and the validation and interpretation requirements specific to molecular assays.
Quality & Safety
Quality control and assurance, proficiency testing, method validation, documentation and laboratory safety — the operational content every credential's exam includes.
How do you get ASCP certified, step by step?
Match the credential to your role and education
Start from the job you want rather than the exam you have heard of. The technician credentials sit at the associate level, the scientist credentials at the baccalaureate level, and the specialist categories assume both a credential and substantial discipline experience. Choosing wrongly wastes an application cycle.
Read the eligibility routes for that credential
Each credential has its own published routes, most combining a degree, an accredited programme and documented laboratory experience. Routes change over time, so read the board's current requirements rather than relying on what a colleague did some years ago.
Assemble verifiable documentation
Transcripts, programme completion and employer verification of experience are checked before you are authorised to test. Experience-route candidates in particular should begin collecting laboratory sign-off early; this is where applications stall.
Sit the adaptive exam and enrol in credential maintenance
Schedule through Pearson VUE. Once certified, the Credential Maintenance Program runs on a three-year cycle requiring continuing education points across defined categories, logged through the board's system.
Some States License the Laboratory — Everyone Regulates Competence
Clinical laboratory testing is federally regulated for quality, and personnel qualification requirements attach to the complexity of the testing performed. On top of that, several states license clinical laboratory personnel directly and reference national certification in their requirements. Where no state licence exists, hospital and reference laboratory policy plus accreditation expectations around documented personnel competence make ASCP certification the practical standard.
