🎯 Role Definition

A Molecular Technician is a highly skilled laboratory professional who serves as the backbone of modern molecular biology and diagnostic labs. This role is fundamentally centered on performing complex tests on biological samples to analyze their DNA and RNA. You are the hands-on expert who translates a biological sample—be it blood, tissue, or other bodily fluids—into crucial data. This data is then used by clinicians for patient diagnosis and treatment decisions, or by researchers to advance our understanding of genetics and disease. Your precision, attention to detail, and technical expertise directly impact patient outcomes and scientific discovery, making this a position of significant responsibility and impact.
