Post-Baccalaureate Certificate in Molecular Diagnostic Sciences

Launch your laboratory career with seven courses dedicated to the exciting, up-and-coming field of molecular diagnostic testing. The George Washington University's (GW) online Post-Baccalaureate Certificate in Molecular Diagnostic Science gives you the knowledge and hands-on experience to work with DNA, RNA, proteins, and lipids to detect, diagnose, and monitor disease and select optimal therapies.

You'll learn the specific clinical laboratory techniques to detect and identify biomarkers at the nucleic acid levels in major areas of medicine including genetic disorders, infectious diseases, cancer, pharmacogenetics, and identity testing. 

Through a series of online coursework and a clinical practicum, you'll complete the certificate ready for a career in helping people get well through effective testing and diagnostics.

Graduate Ready To: 

  • Take the Molecular Biology (MB) Board of Certification examination offered by the American Society for Clinical Pathology (ASCP)
  • Explain the methods of collection, transport, and handling of various specimen types for molecular analysis.
  • Apply molecular-based testing for laboratory utilization and clinical decisions for patient/client outcomes
  • Implement preventive and corrective maintenance programs for equipment and assays
  • Troubleshoot and evaluate appropriate actions for problem resolution
  • Apply knowledge of molecular and genetic theory and principles as they relate to human disease diagnosis
  • Analyze molecular data and patient results to determine test validity and quality
  • Apply ethical decision-making to issues related to molecular laboratory practice

Who is the Ideal Student for this Program? 

  • Students who excel at science-based coursework and are excited by molecular testing's potential for medical science are a good fit for this program.  
  • To handle the online portion of the degree, you must be organized and independent.

Careers in Molecular Diagnostic Testing 

Given the rise of commercialized, at-home DNA testing kits and recently proven medical capabilities particularly in cancer diagnosis and treatment, the need for diagnostic molecular scientists who can ethically and properly manage the challenges of molecular testing and the data it provides is great. 

When you graduate with the online Post-Baccalaureate Certificate in Molecular Diagnostic Science from GW, you'll be prepared to work as a technologist in a diagnostic molecular laboratory, public health laboratory, research institution, law enforcement agency, the molecular section of hospital laboratories, reference laboratory, biotechnology firm, or pharmaceutical company. 

Medical technologists with molecular biology skills earn between $42,364 and $71,695 a year.1
