Lab technician analyzes samples under a microscope during a routine health research procedure.

About this subject

The work of a lab technician is fundamental to the advancement of science and medicine. These professionals are responsible for preparing and analyzing biological samples, such as blood, tissues, and cell cultures, using equipment like the microscope. The routine includes everything from calibrating instruments to interpreting results, which can support diagnoses, research into new drugs, or studies of diseases. In Brazil, technical training in laboratory practice is offered by institutions such as SENAC and state technical schools, typically lasting two years. The demand for these professionals grew significantly during the COVID-19 pandemic, when large-scale testing required skilled teams. Precision and attention to detail are essential skills, as a mistake in analysis can compromise an entire clinical study. Additionally, the technician must follow strict biosafety protocols, using PPE such as gloves, lab coats, and safety glasses. The microscope, invented in the 17th century, remains an indispensable tool, allowing visualization of structures invisible to the naked eye, such as bacteria and cells. Proper lighting, like the midday light depicted in the image, is crucial for obtaining sharp images and preventing eye strain. In many Brazilian laboratories, the routine is intense, with shifts that can extend to 12 hours, especially in university hospitals and public research centers like Fiocruz.
