What is a per diem microbiologist?

Per Diem Microbiologists are laboratory professionals who work on an as-needed or on-call basis rather than as full-time employees. They conduct microbiological tests and analyses to identify microorganisms such as bacteria, viruses, and fungi in samples. Their flexible schedules allow healthcare facilities, research labs, and other organizations to address fluctuating workloads or cover staff absences. Per Diem Microbiologists must have the same qualifications and training as full-time microbiologists, and they play a crucial role in ensuring timely and accurate laboratory results.
