Established in 1999, we have supported over 3,700 bioanalytical studies and are independent of any toxicology or clinical facility and associated schedules. YBS is focused on delivering innovative science to answer our clients complex bioanalytical needs. Our defining core values are: Bioanalytical Expertise; Scientific Excellence; Outstanding Customer Services, Exceptional Quality and Analysis Tailored to Your Requirements

We have two sites in the UK, one in York specializing in Regulatory Bioanalysis and one In Sandwich, Kent specializing in Discovery Bioanalysis, in vitro ADME and Metabolism services. We currently have 22 LC-MS/MS systems across both sites including the latest Waters Xevo TQ-XS (UniSpray), SCIEX TQ 6500+ and the Waters Vion IMS Q-Tof. Supported by the latest UPLC systems, UPC2, Spark Holland Symbiosis on-line SPE systems and Hamilton Microlab STAR workstations. We also have a strong Immunoassay group focused on Regulatory Bioanalysis for biologics and biomarkers with ELISA and MSD technology.

In Regulatory Bioanalysis we are specialists in complex bioanalysis; high sensitivity methods for small molecules, biomarkers and peptides by LC-MS/MS; fast turnaround PK support for FIH studies and microsampling methods (Mitra and Tasso technology).

In Discovery Bioanalysis we provide customized fit-for-purpose bioanalysis for in vivo discovery studies. We provide a broad range of in vitro ADME LC-MS based assays to determine key ADME properties – from early discovery screens to definitive studies. We are also specialists in metabolite characterization from early discovery in vitro studies to late development radiolabeled studies.

York Bioanalytical Solutions is part of Unilabs, which is one of the largest diagnostic providers in Europe, offering laboratory, imaging and pathology specialties, with operations in 20 countries and more than 10,500 employees.
