A cutting-edge device employing volumetric microsampling with capillary and advanced dried blood spot (DBS) technology can collect four equal-volume DBS blood samples from a single finger prick.
Trajan Scientific and Medical’s (Victoria, Australia) hemaPEN is designed to provide a convenient procedure for collecting and storing four DBS samples, thereby enhancing information-rich decision-making. This user-friendly microsampling device can collect four volumetrically identical capillary samples from a single finger stick. The hemaPEN introduces a unique method of capillary sampling with its four integrated capillary tubes within the device for easier handling. The glass capillaries simultaneously draw four samples from a single finger prick, transferring four blood spots onto a DBS cartridge within the hemaPEN.
Designed for one-time use, the hemaPEN is a low-volume sampling device that can collect a sample from any angle, virtually eliminating the risk of under or over-sampling, which benefits users with restricted mobility. Users appreciate the intuitive pen-like design of the hemaPEN and the ability to swiftly collect four microsamples from just one finger prick. Additionally, the hemaPEN ensures the security of samples. After sample collection, users insert the tip of the hemaPEN into its plastic base and push down until a "click" sound is heard, which seals the hemaPEN and transfers the four capillary samples onto four pre-punched DBS papers inside.
Labs that are already equipped for a DBS workflow should find the transition to hemaPEN microsampling methods smooth. Unlike conventional DBS sampling tools, the hemaPEN allows for the collection of an exact and precise fixed micro-volume and is engineered to maintain sample integrity for quantitative analysis. An advantage of the hemaPEN over traditional DBS cards is that it eliminates the need for aliquoting and hole-punching. This is because the hemaPEN collects the four DBS samples onto four pre-punched, industry-standard DBS filter papers within the device. The hemaPEN is suitable for both manual and automated DBS processing workflows. Trajan also provides the hemaPEN opening tool and hemaPEN-QC to assist labs in processing and analyzing DBS microsamples manually or at high throughput. Trajan has received regulatory approval for the clinical use of hemaPEN in Europe and the United Kingdom.
"Our growing range of microsampling technologies allows almost anyone to take an analytically viable sample outside the clinical setting, anytime, anywhere. In our view, that is essential to enable the healthcare systems of the future," said Stephen Tomisich, CEO and founder of Trajan.
