ASI recently supported a large study conducted by the Neuroimaging department at King’s College London examining the brain mechanisms underlying the effects of IV ketamine in treatment resistant depression. Hua, Nina and the rest of the ASI team were extremely supportive and communicative during the set up of the study, and provided highly detailed information on assay options on request. They quoted a competitive price and were extremely flexible to the needs of the study throughout. They analysed the samples in a timely fashion and provided results in a clear and consistent format that met with our internal requirements. Most importantly, they were consistently responsive and helpful during an extended data collection period. I would not hesitate to work with them again.

Having retained ASI's bioanalytical services for 2 clinical trials, ATXA Therapeutics is happy to offer them our fullest commendation not only for their accuracy, timeliness and efficiency but also for their ease and commitment to quality reporting. It was a genuine pleasure working with everyone at ASI.
Therese Kinsella, PhD., MRIA., CEO, ATXA Therapeutics Ltd

We have worked closely with ASI since 2019 when our clinical trial, TOP HAT, commenced. The ASI team have been incredibly supportive from the initial stages of planning and budgeting and flexible when we adapted our initial design. Throughout our time working together the team has been highly responsive to communications and requests and efficient in carrying out the scheduled work on time and to budget and with excellent attention to detail. Relevant data queries have been raised and addressed promptly and quality control procedures were in place to ensure data accuracy. In all, we have had a very positive experience working with the team and grateful for the support provided and would be delighted to collaborate with ASI in future projects.
TOP HAT Team

We recently collaborated with Analytical Services International Ltd. (ASI) based at St. George's, University of London, for a pharmacokinetic research study, and we couldn't be more satisfied with their service. From the initial consultation, ASI's team demonstrated exceptional expertise by thoroughly discussing our specific needs and providing a precise quotation. Both Nina and Hua were highly responsive when I needed to arrange sample analysis. They seamlessly arranged courier sample collection, ensuring a smooth and hassle-free process for our team. The results were delivered promptly within our research timeframe, allowing us to progress our study efficiently. ASI's commitment to quality and timely service has made them an invaluable partner in our research efforts. We highly recommend ASI for their outstanding drug quantification services.
