Description

Description: Capitainer® B accurately collects 10 μl whole blood from finger stick. Developed to be easy to use with guaranteed sample quality.Automatically meters 2×10µl of bloodSuccessful sampling indicator integrated in the deviceThe design eliminates the risk of over- or under-fillThe inlet material guides the blood drop into the device.Dried non biohazard sample, return by regular mail to the labCapitainer’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.Example Analytes:Antibodies / DNA, RNA / Proteins / Therapeutic Drugs / Drugs of Abuse / Trace ElementsThe next generation dried blood spot sampling cards DBS has been used since the 1960s when introduced in newborn screening. 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 viscosity, 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 technology of the Capitainer® B card provides an exact 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 have been published for over 2000 analytes from conventional DBS, these can now be developed into quantitative tests with the new generation of DBS cards from Capitainer.SizeDimensions: 78 x 43 x 3 mmSample volume: 2 x 10 µlMaterialDBS paper: Ahlstrom grade 222>80% of the device is paper based<1,2 grams of plastics per deviceOperating ConditionsTemperature range: +15°C to +35°CRelative humidity range: 15% to 90%Hematocrit value: 25% to 55%The card must be used within 30 minutes from opening the packageSample StorageCollected DBS 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. DBS 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.DisposalDispose according to local regulations. Take care with blood stained materials and sharps.RegulatoryCapitainer B is CE-marked, registered as an IVD product according to the 98/97EC In vitro Diagnostic Medical Device Directive and registered with the US FDA as a Device Class 1.
