Collection Device Update: Chemistry β-hCG testing

Effective March 21, 2025, Corewell Health Laboratories will update the preferred specimen type for β-hCG testing from plasma to serum (mint green top, lithium heparin gel to gold top, serum separator-SST gel). The move to serum is mostly driven by the laboratory’s need to reduce assay performance problems that can occur sporadically with the use of plasma. Although serum is the preferred specimen type plasma will remain an acceptable container.
If you have questions regarding the preanalytical handling process and the optimum tube offering, contact the lab for support.
