By Dr. Zubair Khalid, DVM, MS, PhD · 2026-08-27

Quick Answer

• Meet the education and clinical experience requirements for the Molecular Biology (MB) certification pathway that matches your degree level.
• Submit a completed application through the ASCP Board of Certification portal with official transcripts and documentation of your laboratory experience.
• The certification exam covers molecular diagnostics, techniques, and laboratory operations, so preparation should focus on those domains.

Understanding ASCP MB Certification

The ASCP MB certification is a professional credential for medical laboratory scientists who specialize in molecular biology techniques used in diagnostic testing. The American Society for Clinical Pathology Board of Certification administers this credential to verify that a laboratory professional has the knowledge and skills needed to perform molecular testing accurately and safely. This certification is distinct from general medical laboratory scientist certification because it focuses specifically on molecular methods, including nucleic acid extraction, amplification, and analysis.

For laboratory professionals, the MB credential signals competence in a specialized area of diagnostic testing. Molecular biology techniques are used in many areas of clinical laboratory medicine, including infectious disease testing, oncology, genetics, and pharmacogenomics. The certification process is designed to confirm that the individual understands both the technical procedures and the underlying principles that govern molecular testing.

The ASCP BOC offers the MB certification to individuals who meet specific education and experience requirements. These requirements vary depending on the applicant's educational background and the type of laboratory experience they have completed. The certification process involves submitting an application, providing documentation of eligibility, and passing a comprehensive examination.

Understanding the Certification Body

The American Society for Clinical Pathology Board of Certification is the organization that administers the MB certification. The ASCP BOC is responsible for establishing the eligibility requirements, developing the examination, and issuing credentials to qualified candidates. The certification is recognized in the United States and is often required or preferred by employers in clinical laboratories.

The ASCP BOC offers several certification categories for laboratory professionals. The MB certification is one of the specialist-level credentials, which means it requires a higher level of education and experience than the entry-level certifications. The certification is designed for professionals who work specifically in molecular diagnostics laboratories.

The certification process is governed by the ASCP BOC's policies and procedures. These policies are updated periodically to reflect changes in the field and in laboratory practice. Candidates should review the current requirements before applying, as the requirements may change over time.

Eligibility Requirements

The eligibility requirements for the ASCP MB certification depend on the applicant's educational background and laboratory experience. The ASCP BOC has established several routes to eligibility, each with its own specific requirements.

Route 1: Bachelor's Degree with Molecular Biology Experience

The most common route to the MB certification requires a bachelor's degree from a regionally accredited college or university. The degree must include coursework in molecular biology, biochemistry, genetics, or a related field. In addition to the degree, the applicant must have at least one year of full-time experience in a molecular biology laboratory.

The laboratory experience must be in a clinical laboratory, a research laboratory, or a laboratory that performs molecular testing. The experience must include hands-on work with molecular techniques, such as nucleic acid extraction, amplification, and analysis. The experience must be documented by the applicant's supervisor or laboratory director.

Route 2: Medical Laboratory Scientist Certification

Applicants who already hold the ASCP MLS certification may be eligible for the MB certification through a different route. These applicants must have a bachelor's degree and must have completed coursework in molecular biology. They must also have at least one year of experience in a molecular biology laboratory.

This route recognizes that medical laboratory scientists already have a strong foundation in laboratory science. The additional molecular biology experience ensures that the applicant has the specific skills needed for molecular diagnostics.

Route 3: Graduate Degree

Applicants with a master's degree or doctoral degree in molecular biology, genetics, or a related field may be eligible for the MB certification. The graduate degree must be from a regionally accredited university. In addition to the degree, the applicant must have at least one year of experience in a molecular biology laboratory.

The graduate degree route is designed for individuals who have advanced education in molecular biology but may not have formal training in clinical laboratory science. The experience requirement ensures that the applicant has practical laboratory skills in addition to theoretical knowledge.

Route 4: International Applicants

Applicants who received their education outside the United States may be eligible for the MB certification. These applicants must have their transcripts evaluated by a credential evaluation service to determine if their education is equivalent to a US bachelor's degree. They must also meet the experience requirements.

International applicants must also demonstrate proficiency in English. The proficiency can be demonstrated through a standardized test or through documentation of education or work experience in an English-speaking environment.

The Application Process

The application process for the MB certification involves several steps. The process is designed to verify that the applicant meets the eligibility requirements and to collect the information needed to schedule the examination.
