HSL Biochemistry

HSL Biochemistry provides a high-quality, safe and effective service that facilitates the clinical care of patients. The service is set up across the HSL network of laboratories based on the hub-and-spoke model.

The service includes routine, high-volume biochemistry testing provided through the rapid response laboratories (RRLs) located at each associated Trust site, combined with the specialist biochemistry service delivered from the hub laboratory (The Halo building). These services are supported by fully automated and tracked instruments, comprising general chemistry and immunoassay analysers on multiple platforms.
