With their standardized, microsystem based sampling technology, Capitainer SE have developed a groundbreaking solution for near-patient blood sampling of volume defined Dried Blood Spots (DBS). Patients are able to conveniently collect their own blood samples at home and mail them to a laboratory for analysis using an innovative DBS card that allows the sampling of an exact volume of blood regardless of the sample’s hematocrit.
Patients simply place a drop of blood on the DBS card which automatically fills a microchannel with the required amount and discards excess blood. This ensures that the blood sample always corresponds exactly with the required amount. The blood volume in the microchannel is automatically transferred to a pre-punched DBS paper, forming an accurate and high-quality dried blood spot sample, preserved for quantitative analysis. The potential for human error is eliminated almost completely.
