By Dr. Zubair Khalid, DVM, MS, PhD ·
Quick Answer
- Choose ASCP MB certification when you need a widely recognized credential for clinical laboratory work in hospital and reference laboratory settings.
- Choose ABMGG accreditation if you plan to direct a clinical molecular genetics laboratory and have completed an accredited fellowship.
- State licensure requirements vary by state and may apply independently of national certification, so verify your state's regulations before applying.
Understanding the Certification Landscape
Molecular diagnostics professionals face a crowded field of credentials that serve different purposes. The three primary pathways are the American Society for Clinical Pathology (ASCP) Molecular Biology (MB) certification, the American Board of Medical Genetics and Genomics (ABMGG) certification, and state-issued laboratory personnel licenses. Each pathway has distinct eligibility requirements, examination content, costs, renewal obligations, and career implications.
The confusion among laboratory professionals is understandable because job postings often list multiple credentials as acceptable. A position may state that applicants must hold ASCP MB certification or a state license, while another posting requires ABMGG certification for a laboratory director role. Understanding the differences helps you match your credential to your career trajectory.
The U.S. Bureau of Labor Statistics Occupational Outlook Handbook describes the broader context for these roles. Medical laboratory technologists and technicians perform tests on body fluids, tissue, and other substances, and they work in hospitals, diagnostic laboratories, and physicians' offices. The handbook also notes that clinical laboratory technologists typically need a bachelor's degree, while technicians may need an associate degree. This educational foundation is the starting point for all three certification pathways.
ASCP Molecular Biology Certification
The ASCP Board of Certification offers the Molecular Biology (MB) credential for medical laboratory professionals who perform molecular diagnostic testing. This certification is designed for individuals who work in clinical laboratories and need to demonstrate competence in molecular techniques.
Eligibility Requirements
ASCP MB certification requires a combination of education and laboratory experience. The eligibility pathways vary based on your educational background. A bachelor's degree in a biological science or a related field is the most common entry point. You must also complete a specific number of hours of molecular biology laboratory experience under the supervision of a qualified professional.
The experience requirement is structured around the type of degree you hold. For example, a candidate with a bachelor's degree in a biological science must complete a defined number of months of full-time molecular biology experience. Candidates with a master's degree or doctoral degree may have reduced experience requirements. The ASCP Board of Certification publishes the exact eligibility pathways on its website.
Examination Content
The ASCP MB examination covers the full scope of molecular diagnostics practice. The exam includes questions on nucleic acid extraction, amplification techniques, hybridization methods, and analysis of results. It also covers quality control, quality assurance, and laboratory safety. The examination is computer-based and consists of multiple-choice questions.
The exam content is weighted toward the practical skills that molecular laboratory professionals use daily. The largest portion of the exam focuses on testing procedures and methodologies. A smaller portion covers quality control and laboratory operations. The ASCP Board of Certification publishes a detailed content outline that lists the topics and their relative weight on the examination.
Cost and Renewal
The ASCP MB certification requires an application fee and an examination fee. The fees are set by the ASCP Board of Certification and are published on their website. Certification is valid for a defined period, typically three years. To maintain certification, you must complete continuing education credits and pay a renewal fee.
The renewal process requires you to document your continuing education activities. The ASCP Board of Certification accepts a range of activities, including attending professional conferences, completing online courses, and publishing peer-reviewed articles. You must accumulate a specific number of continuing education credits during each three-year cycle.
Career Impact
ASCP MB certification is widely recognized in clinical laboratories across the United States. Many hospital laboratories and commercial reference laboratories require or prefer this certification for molecular diagnostics positions. The certification demonstrates that you have met a national standard of competence in molecular biology testing.
The Occupational Outlook Handbook notes that certification can be beneficial for medical laboratory professionals. The handbook states that some employers require certification for certain positions, and certification may also be required for state licensure. The ASCP MB certification is one of the credentials that can satisfy these requirements.
ABMGG Certification
The American Board of Medical Genetics and Genomics (ABMGG) offers certification for professionals who direct clinical molecular genetics laboratories. This certification is distinct from the ASCP MB credential because it is designed for laboratory directors instead of bench-level technologists.
Eligibility Requirements
ABMGG certification requires completion of an accredited fellowship program in molecular genetics. The fellowship is typically two years in duration and includes both clinical and laboratory training. You must also hold a doctoral degree, such as a PhD, MD, or DO.
The fellowship must be completed at a program accredited by the Accreditation Council for Graduate Medical Education (ACGME). During the fellowship, you gain experience in molecular diagnostics, including test development, validation, and interpretation. You also receive training in laboratory management and quality assurance.
The Exam
The ABMGG certification examination is a comprehensive assessment of your knowledge and skills in molecular genetics. The exam covers the scientific basis of molecular genetics, laboratory techniques, and clinical interpretation. It also covers the regulatory and quality requirements for clinical laboratories.
The examination is offered once per year and is administered by the ABMGG. The exam is a written examination that includes multiple-choice questions and case-based questions. The case-based questions require you to interpret molecular test results and make clinical recommendations.
Cost and Renewal
The ABMGG certification requires an application fee and an examination fee. The fees are set by the ABMGG and are published on their website. Certification is valid for a defined period, typically ten years. To maintain certification, you must participate in continuing education and pass a recertification examination.
The recertification process requires you to demonstrate that you have maintained your knowledge and skills in molecular genetics. You must complete a defined number of continuing education credits and pass a recertification examination. The ABMGG publishes the recertification requirements on its website.
Career Impact
ABMGG certification is required for directors of clinical molecular genetics laboratories. The Clinical Laboratory Improvement Amendments (CLIA) regulations require that laboratory directors have the appropriate qualifications. ABMGG certification is one of the qualifications that satisfies the CLIA requirements for a molecular genetics laboratory director.
The career path for ABMGG-certified professionals is different from that of ASCP MB-certified professionals. ABMGG-certified professionals typically hold leadership positions in clinical laboratories, academic medical centers, and research institutions. They are responsible for the overall operation of the laboratory, including test development, validation, and interpretation.
State Licenses
State licenses are issued by individual states and are required for certain laboratory professionals. The requirements for state licensure vary by state. Some states require licensure for all laboratory professionals, while others only require licensure for certain positions.
States That Require Licensure
Several states require laboratory professionals to hold a state license. These states include California, Florida, New York, and others. The requirements for licensure vary by state, but they typically include a combination of education, experience, and examination.
California has some of the most stringent licensure requirements in the country. The California Department of Public Health requires laboratory professionals to hold a license in the specific specialty in which they work. For molecular biology, the relevant license is the Clinical Molecular Biologist license. To qualify for this license, you must have a bachelor's degree, complete a defined amount of laboratory experience, and pass a state examination.
New York also requires laboratory professionals to be licensed. The New York State Department of Health requires a license for laboratory professionals who work in clinical laboratories. The license requirements include a bachelor's degree, laboratory experience, and a passing score on a state examination.
How State Licenses Interact with National Certifications
State licenses and national certifications are separate credentials. A national certification, such as ASCP MB, does not automatically qualify you for a state license. You must apply for a state license separately and meet the state's specific requirements.
Some states accept national certifications as part of the licensure requirements. For example, a state may require that you hold a national certification and pass a state examination. Other states may require that you complete a specific amount of laboratory experience in addition to holding a national certification.
Career Impact
State licenses are required for laboratory professionals who work in states that have licensure requirements. If you plan to work in a state that requires licensure, you must obtain the license before you can begin work. The license is tied to the state, so you must apply for a new license if you move to another state.
The career impact of a state license is significant for professionals who work in states with licensure requirements. Without a license, you cannot work in a clinical laboratory in those states. The license also demonstrates that you have met the state's requirements for laboratory practice.
