PK4 Laboratories uses our proprietary high-yield procedure to isolate PBMCs with an emphasis on high viability and recovery. As the only national network of PBMC processing labs, we work directly with research clinics and pharmaceutical sponsors to process and store cells in accordance with sponsor-provided methodology and criteria.



PK4 Laboratories operates under relevant laboratory accreditation standards including GCP and ISO17025. These standards are maintained and monitored closely at each of our locations.
