WELCOME TO QPS
A GLOBAL LEADER IN BIOANALYSIS, PRECLINICAL
AND CLINICAL RESEARCH SERVICES
Over 800 Assays Available
Momentum That Matters
Discovery to Approval: One Partner, Every Step
For 30 years, QPS has been the CRO that scientists and development teams trust when timelines are unforgiving and data quality is non-negotiable. From the first bioanalytical assay to clinical trial conduct, we bring the precision of a specialized lab, the commitment to design a custom-built program that meets your individual needs, and the reach of a global network to get it done. With QPS custom-built research, you get a one of a kind program, designed around your program’s specific needs, rather than a one-size fits all solution.
Why Sponsors Choose QPS
Founder-Led. Globally Trusted for Decades.
Dr. Benjamin Chien founded QPS in 1995 to provide high quality bioanalytical LC-MS/MS contract services. Since then, QPS has posted impressive growth every year and has grown from a small molecule bioanalysis shop of three people to a global powerhouse with more than 1,250+ employees in the US, EU, Asia and India.
Over the years, the company has added additional services, including Pharmacology, Toxicology, DMPK, Translational Medicine, Central Safety Laboratory & PBMC Services, Early Phase I – IIa Clinical Research Units and Phase IIb – IV Clinical Research Operations Services.

We Don't Manage Your Study. We Own It With You.
Most CROs hand you a project manager and a portal. QPS gives you a senior, client-dedicated team that takes real ownership, from protocol design through final report. Your Project Manager is your single point of contact for the entire study duration, eliminating the communication gaps that kill timelines and inflate budgets.
We built our reputation on bioanalysis, specifically the kind of high-precision LC-MS/MS work that launched careers in 1995 and still anchors drug development in 2026. That foundation shows when you experience how we approach every engagement: with scientific rigor, not just operational process.
End-to-End Drug Development
From Molecule to Medicine
The most expensive thing in drug development is starting over with a new CRO, and QPS clients rarely have to take this drastic step. Our capabilities span the full development continuum, and our teams collaborate across divisions so your data stays consistent, your context doesn’t get lost, and your program keeps moving.

Don't Wait for Method Development to Get Started
The QPS Assay Finder is the industry’s most practical tool for bioanalytical procurement decisions. Search our validated library of small molecule, large molecule, and genomic biomarker assays, and know whether your analyte is already covered before you call to get started. Of course, method development and validation for new compounds are QPS core competencies, so we can also get you started from scratch.
Time Is the One Thing You Can't Get Back
Every week that a study falters or stalls is a week your compound isn’t progressing toward the patients who really need it. QPS protects your timeline with the scientific credibility, regulatory relationships, and global infrastructure to back up that commitment.
Whether you’re looking for a single preclinical or bioanalytical service, a stand-alone clinical trial, or a partner for your entire development program, the conversation starts with one message.
