Bioanalytical Capabilities

Scantox provides a comprehensive bioanalytical package of LC-MS/MS method development, validation, and sample analysis. Our bioanalytical experts bring experience and scientific knowledge to guide your assay strategy from exploratory to regulatory studies.


  • Assay of organic compounds
  • Analytical method development
  • Analytical method validation ensuring adherence to ICH and/or EMA guidelines
  • Sample analysis for toxicological & pharmacokinetic studies meeting GLP/GCP standards
  • Analytical method transfer
  • Batch control testing of raw materials & finished products, in line with GMP standards
Type of projects
Specialized in customized solutions for pharmacokinetic (PK) and toxicokinetic (TK) studies, focusing on precise measurement of new drugs in specific matrices. Our expertise extends to developing novel methodologies for analyzing new modalities. We offer robust assays that ensure sensitive and quantitative measurements of drug concentrations.
Molecule types
Specialized not only for small organic molecules but also peptides with a molecular weight of less than 10kDalton.
Extensive experience with a wide spectrum of biological matrices, including but not limited to serum, blood, tissues, cells, spinal fluid, tears, and urine.
Turnaround time
Capabilities and resources allow quick turnaround times. Typically, we require three weeks for method development and another three for method validation, subject to project specifics.

What is LC-MS/MS?

LC-MS/MS is recognized as the gold standard technology used for the bioanalysis of small molecules in drug discovery and development. This technology is instrumental in the qualitative and quantitative analysis of drugs and other compounds in biological fluids and tissues. Its application spans across various study phases, from non-GLP exploratory research to GLP-compliant studies to GCP clinical trials.


At Scantox, dedication to excellence is at the core of every action. We adhere to the highest standards of GMP, GLP, and GCP. This commitment is validated through regular audits by SWEDAC and the Swedish Medical Products Agency (MPA), alongside inspections from our clients, ensuring compliance with these critical regulations.

We validate our methodologies in strict accordance with the International Council for Harmonisation (ICH) guidelines and the European Medicines Agency’s (EMA) guidelines for bioanalysis. This ensures that our processes meet global standards for quality and reliability.
