Capitainer AB

Capitainer AB is a Swedish medtech company founded in 2013 by Professor Olof Beck from the Karolinska Institute, specializing in intelligent microsampling devices for remote blood and fluid collection. The company's proprietary microfluidic technology enables patients to collect precise volumes of whole blood, cell-separated plasma, and other fluids at home, which can be mailed to laboratories for analysis without specialized handling or trained phlebotomists. Capitainer's flagship product, the Capitainer qDBS (quantitative Dried Blood Spot), delivers volumetric accuracy equivalent to traditional pipetting while featuring an integrated success indicator and high first-time-user success rates. The company also offers automated sample handlers and solutions for clinical diagnostics, chronic disease monitoring, immunosuppressive drug sampling, infectious disease serology, and oncology screening applications. Capitainer targets healthcare providers, clinical laboratories, and diagnostic organizations seeking cost-effective, convenient alternatives to traditional venipuncture-based blood collection.
