A clinical lab assistant works in a medical lab, helping senior researchers to assess, analyze, and discover diseases and other medical issues. The duties of these technicians include inspecting specimens and running routine and specialized tests. They also maintain records, which are used to make reports to doctors or patients. Qualifications for this career include a bachelor’s degree in biology, medical sciences, or a related field, as well as experience or training in a lab setting. Depending on state laws, clinical lab assistants may need certification. Other skills include attention to detail and strong written and verbal communication.

To thrive as a Clinical Lab Assistant, you need a strong background in biology or medical laboratory technology, attention to detail, and typically a certificate or associate degree in a related field.
