Our Bioanalytical Capabilities
ASI offers a comprehensive range of clinical bioanalysis services designed to meet the needs of modern drug development.
Pharmacokinetic and Metabolite Profiling
We provide detailed pharmacokinetic data that supports dose selection, safety evaluation and regulatory submission. Our scientists also perform metabolite identification and analysis to help characterise drug behaviour across different populations.
Small Molecule Analysis
Our team has extensive experience with a wide range of small molecules, including psychedelics, antibiotics, steroids, cardiovascular drugs and treatments for mental health conditions. We specialise in the analysis of complex and unstable compounds.
Biomarker and Speciality Assays
We develop and validate small molecule biomarker assays to support exploratory research and clinical studies. We also provide quantification of compounds such as GLP-1 receptor agonists.
Chiral Separations
For compounds where enantiomeric selectivity is clinically relevant, we offer chiral separation and analysis with high sensitivity and precision.
Dry Blood Spot Bioanalysis
We support studies that require microsampling through validated dry blood spot analysis, enabling minimally invasive collection and simplified logistics.
