DIESSE Diagnostica Senese S.p.A. is an Italian manufacturer of innovative clinical systems. DIESSE was founded in 1982, thanks to a partnership between financial investors and top level researchers with long-standing experience in developing clinical diagnostic products and systems.

Throughout its twenty-four year history, DIESSE has focused its efforts on developing a solid position in the market of hematology and infectious disease test systems. In the early years, the company capitalized on its reputation for manufacturing quality and excellent products for serology testing which allowed the company to expand its activities to other strategic markets.

The initial development was greatly assisted by the invention and subsequent patenting of a revolutionary method for the determination of the erythrocyte sedimentation rate (ESR). Based on this technology, DIESSE developed the VESMATICâ„¢ SYSTEM, which reduces the turn-around time of ESR testing by more than fifty percent eliminates the risk of direct exposure to blood samples. Additionally, VESMATIC Systems offer added safety and convenience through the use of non-glass tubes and small sample volume requirements.
