Expediting innovative technologies to moderate human diseases - a full-stack clinical mass spectrometry company.
A 190-pixel-wide wordmark that opens onto a lab where a machine reads the chemistry of your blood. Founder Hua-fen Liu spent decades inside SCIEX and Roche before deciding the mass spectrometer belonged in the hospital, not the museum.
Here is a fact that precision-medicine marketing rarely mentions: a mass spectrometer is only half of a diagnostic test. The machine produces a signal. Turning that signal into a number a doctor can trust - reliably, this year and next, in this lab and that one - requires reagents, calibrators, and certified reference materials. That second half is unglamorous, chemical, and enormously hard. Calibra Scientific Inc. decided to make all of it.
Legally it is Hangzhou Calibra Diagnostics Co., Ltd. - in Chinese, 凯莱谱, a name that ends in the character 谱, the same one used in the word for "spectrum." The company describes itself, without much modesty, as "the industry-leading integrated mass spectrometry innovation application platform." Strip the adjectives and the claim is concrete: Calibra sells the instrument, the reagent kits, the reference materials, and the lab services that connect them. In an industry where most players own one link of that chain, owning all four is the whole strategy.
The pitch works because clinical mass spectrometry has a measurement problem, not a science problem. The science - liquid chromatography paired with tandem mass spectrometry, LC-MS/MS - has been settled for years. What's unsettled is reproducibility at scale: getting the ten-thousandth patient's result to mean exactly what the first patient's result meant. Calibra's answer is vertical integration, which is a fancy way of saying: if the reference material matters that much, we'll make our own.
Founder and CEO. One of the early pioneers of the clinical mass spectrometry industry in both the US and China. Before Calibra she was Global Director of SCIEX Labs and a director of application and support at SCIEX, a Danaher company, with earlier research roles at Roche and Pfizer. She has published more than 100 peer-reviewed papers in journals including Cell and Nature Biotechnology, and won AOAC International's "Technical and Scientific Excellence of the Year" award for 2015-2016 - before she had a company to put it on.
Founder-market fit is an overused phrase, but consider the resume: keynote speaker, prolific author, industry veteran - then she goes and builds the company that productizes the field she helped pioneer. It reads less like a career pivot and more like a logical conclusion.
EVP, Sales & Services. 30+ years in China's mass spectrometry market, formerly Thermo Fisher and SCIEX. Championed the "instrument + reagent" package model.
VP & Chief Chemist. Founded reference-materials maker Alta Scientific in 2012; joined via Calibra's 2022 acquisition. Directs a Tianjin key lab for standard substances.
"The hard part isn't one great measurement. It's the ten-thousandth identical measurement."
— The thesis behind Calibra's vertical integration
Calibra sells the full stack. That's the interesting part - most competitors ship one layer of it.
A high-end, IVD-registered clinical mass spectrometry detection system. NMPA-cleared in March 2022 and engineered to live in a hospital lab, not a research bench.
Proprietary metabolomics and proteomics R&D and productization platform, capable of accurate qualitative and absolute quantitative analysis of 300+ metabolites.
10+ NMPA Class II clinical mass spectrometry reagent kits and 300+ validated clinical testing assays - the chemistry that turns signal into diagnosis.
Certified reference materials and stable isotope-labeled substances, brought in-house through the late-2022 acquisition of Alta Scientific.
Medical laboratory testing and translational multi-omics research services for hospitals and research institutions.
The commercial engine: sell the platform, then the recurring reagents, calibrators and standards that keep it running - the razor-and-blades logic of diagnostics.
Hospitals and research units served nationwide across China.
Invention patents, software copyrights and utility-model patents.
Validated on the platform, from a single integrated stack.
Papers and expert-consensus guidelines in Cell, Cell Reports, Cell Discovery and more.
Calibra is a DIAN Diagnostics-invested company - a distribution advantage most diagnostics startups only dream about, since the hospital network is already on the phone. On top of that it raised institutional venture rounds through 2022.
Reported totals vary by source (roughly $23M-$64M across databases). Figures are approximate and drawn from public reporting; exact valuation is not disclosed.
Hua-fen Liu establishes the company in Hangzhou to build an integrated clinical mass spectrometry platform.
Calibra advances its proprietary multi-omics metabolomics and proteomics R&D platform.
The high-end clinical mass spectrometry system receives NMPA registration - clearance to sit in clinical labs.
CICC Jiatai Fund leads, with Fosun, Qishen, Xihu and CICC Pucheng participating.
A growth round closes and Calibra acquires reference-materials maker Alta Scientific, bringing standards in-house.
Vision: to become a leader in the precision diagnostics industry.
Mission: empowering healthier life with innovative diagnostics.
Slogan: "Expediting innovative technologies to moderate human diseases."
Guided, the company says, by clinical needs, the best user experience, and a quality standard of excellence.
Calibra's Chinese name, 凯莱谱, ends in 谱 ("pu") - the same character used in "spectrum," a quiet nod to mass spectrometry.
Founder Hua-fen Liu won a scientific-excellence award from AOAC International before she ever started the company.
Chief chemist Dr. Lei Zhang directs a Tianjin key laboratory for standard substances and stable-isotope labeling.
Calibra sells both the mass spectrometer and the reference materials used to calibrate it - the razor and the blades.
Calibra does not publish an official channel we could verify, so these are open searches to the most relevant clinical mass spectrometry and Calibra content - not endorsed links.
It develops integrated clinical mass spectrometry solutions - instruments, reagent kits, certified reference materials, and central-lab / multi-omics services - for precision diagnostics.
Hua-fen Liu, a veteran of SCIEX, Danaher, Roche and Pfizer, founded the company in Hangzhou around 2016-2017.
CalQuant-S is Calibra's high-end, NMPA-registered clinical mass spectrometry (LC-MS/MS) detection system, cleared in March 2022 for use in clinical laboratories.
It raised a CNY 220M Series B+ in May 2022 led by CICC Jiatai Fund and a Series C in December 2022, and is a DIAN Diagnostics-invested company.
The company reports serving more than 20,000 hospitals and research institutions across China, with 300+ clinical assays and 100+ patents.
