The Diesse Mini-Cube, manufactured by Diesse Diagnostica Senese SpA, Milan, Italy, and distributed by Streck Inc, Omaha, Neb, is an automated instrument for erythrocyte sedimentation rate (ESR) testing in ethylenediaminetetraacetic acid (EDTA) tubes. The benchtop instrument produces ESR results directly from EDTA tubes without consuming the patient sample. The closed testing system reduces exposure to potentially infectious materials. Random access improves lab workflow, as no batching is required. Results are available in 20 minutes and automatically print and transmit to laboratory information systems. The device has a greater than 95% correlation to the modified Westergren method for determining ESR. A barcode scanner ensures positive patient identification. For more information, visit Streck.
