What is a per diem CLS?

A Per Diem CLS (Clinical Laboratory Scientist) is a laboratory professional who works on an as-needed basis, rather than having a set full-time or part-time schedule. Per diem CLSs are often called in to cover staff shortages, busy periods, or specific shifts in hospitals and clinics. They perform the same laboratory tests and analyses as regular CLSs, ensuring accurate and timely results to assist in patient care. This flexible role allows both the employer and the employee to adapt to changing workload demands.

Per Diem Clinical Laboratory Scientists (CLS) often work in multiple facilities or cover shifts on short notice, which means they must quickly adapt to different laboratory protocols, instrumentation, and team dynamics. A common challenge is staying updated with varying procedures and maintaining familiarity with diverse lab information systems. To prepare, it’s beneficial to review each facility’s standard operating procedures in advance and maintain strong communication with permanent staff. Flexibility, attention to detail, and a proactive approach to learning are key qualities for success in this dynamic role.

What are the key skills and qualifications needed to thrive as a per diem CLS?

To thrive as a Per Diem CLS, you need a bachelor's degree in medical technology or a related field, a valid CLS license, and strong analytical laboratory skills. Familiarity with laboratory information systems (LIS), automated analyzers, and quality control protocols is typically required. Attention to detail, adaptability, and effective communication are essential soft skills for working independently and efficiently in varying clinical settings. These competencies ensure accurate test results, patient safety, and smooth integration into different laboratory teams as needed.
