Molecular diagnostics is an area of medical laboratory research that involves studying human genetics through a DNA and RNA sample to learn more about how they contribute to biological disease. Your responsibilities in molecular diagnostics are to aid research efforts through studying samples and reporting findings. Jobs in molecular diagnostics include genetic testing specialist, lab technician, research scientist, and testing supervisor. Your duties as a specialist are to explain procedures to a patient, obtain their history, and collect a sample. Lab technicians analyze samples, while research scientists use samples to learn more about the DNA/RNA-disease relationship. Supervisors oversee other molecular diagnostics workers in a facility or lab.
