Dried Blood Spots (DBS): simple, minimally invasive sample collection on filter paper for reliable laboratory diagnostics, transport, and long-term storage.
In Stock
Dried Blood Spots (DBS) represent a simple yet powerful innovation in modern diagnostics. With just a drop of capillary blood collected from the fingertip, applied to specialized filter paper, and allowed to dry, DBS technology offers laboratories and clinicians a reliable, traceable, and minimally invasive solution for sample collection.
Euroimmun’s product portfolio, ideally complemented by highly sophisticated devices for punching dried blood cards, enables fully automated processing of serological tests based on DBS samples. Barcoded blood collection cards guarantee end-to-end traceability from sample collection through to result reporting, ensuring data integrity at every step.
To meet the needs of different laboratory sizes and throughput demands, flexible automation options are available:
All instruments can connect directly to a laboratory information system (LIS) via integrated software, or centrally managed through the EUROLabOffice 4.0 middleware, which consolidates, channels, and displays all relevant information for efficient workflow management.
DBS technology is widely adopted across newborn screening, infectious disease testing, therapeutic drug monitoring, genetic research, and epidemiological studies. Its stability at ambient temperature, low biohazard risk, and compatibility with automated Euroimmun systems make it particularly valuable for decentralized collection sites and resource-limited regions.
By combining the simplicity of DBS collection with Euroimmun’s advanced automation portfolio, laboratories can expand diagnostic access, streamline workflows, and ensure consistent, reproducible results. From DBS Punchers® to EUROIMMUN analyzers, every stage of the process is supported with robust instruments, software integration, and middleware for full digital traceability.
