Lab technician looking through microscope

Lab technician analyzes samples under microscope during routine research at a Brazilian institution.

About this subject

The lab technician, a key professional in research centers and hospitals, uses the microscope to examine slides with biological samples such as cells, tissues, or microorganisms. In Brazil, these professionals work in laboratories at public and private universities, research institutes like Fiocruz, and reference hospitals. Their routine includes sample preparation, equipment calibration, and observation recording, following strict biosafety protocols. The optical microscope, the central tool, allows magnifications up to 1000x, enabling the identification of cellular changes indicative of diseases like cancer or infections. Lab technicians undergo technical or higher education in fields such as Biomedicine or Clinical Analysis, with mandatory practical internships. Demand for these professionals surged during the COVID-19 pandemic, when mass testing required trained teams to process millions of exams. In Brazil, the Federal Council of Biomedicine regulates the profession, requiring an active license for legal practice.
