About Dried Blood Spot Sampling
DBS has been used since the 1960s when introduced in newborn screening. However, a major drawback of conventional DBS cards is the lack of volumetric control and the hematocrit (Ht) effect. As a different Ht, due to different blood viscousity, leads to different spot size a standardized subpunch on conventional DBS does still not provide an exact volume. These limitations reduce conventional DBS to qualitative or semiquantitative analysis, while most clinical tests are quantitative.
The microfluidic qDBS technology of the Capitainer®B card provides an exact sample volume to a pre-cut DBS disc. Since the full volume defined spot is used for analysis, the Ht effect is overcome and the microsample can be used for quantitative tests. Methods are published for over 2000 analytes using conventional DBS. Now, these can be developed into quantitative tests with the next generation of DBS cards from Capitainer.
