The Next Generation Dried Blood Spot Sampling Cards
Capitainer®B 50 accurately collects 50 μl whole blood from finger stick. It is developed to be easy to use with guarantied sample quality. Capitainer’s paper based drying pouch allows the sample to dry during transportation. No drying step is required by the user. All aspects of the device are designed to make sampling easy for the user.

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.

Collected qDBS samples can be stored at room temperature.
The stability of individual analytes in DBS samples should be validated by the responsible laboratory. In general, stability increases with lower temperature and lower humidity. qDBS discs can be stored in the freezer to extend stability. Please refer to the extensive literature for traditional DBS samples as guidance for individual analytes.
Dispose according to local regulations. Take care with blood stained materials and sharps.
