Familiarity with laboratory equipment, safety protocols, and software for data analysis (such as LIMS) is typically required, and some roles may prefer certifications like ASCP. Excellent organizational skills, communication, and the ability to follow precise procedures are crucial soft skills for success. These competencies ensure accurate test results, maintain lab safety, and uphold quality standards in scientific environments.
