Specimen Processing Technician (SPT)

The ASCP Specimen Processing Technician (sometimes referenced as a route into the MLA credential track) targets the pre-analytical workflow that keeps laboratory analyzers fed and reliable. The exam emphasizes specimen identification criteria, centrifuge operation, aliquot preparation, storage requirements, rejection criteria for hemolyzed, lipemic, icteric, and clotted specimens, and basic safety. Many hospital laboratories use this credential as an internal career ladder for phlebotomists who wish to step away from patient-facing work into lab operations. Eligibility requires a high school diploma plus either an approved program or six months of full-time specimen processing experience.
