A blood collection device for microsampling
with predefined blood volume

The Capitainer qDBS product is a two channel blood sampling
card that collects 10.0 microliter whole blood as dry blood spots by a simple finger prick.

Indications for use

The Capitainer qDBS sample card is intended for the collection and storing of a fresh whole blood sample as a dried blood spot.

The blood sample can then be analyzed in a lab to determine the quantitative presence of any targeted
compound. A large blood drop from a finger prick
(> 18 μl) should be applied to the device. When sampling is completed, close the card and place in the return pouch. The sample will dry in the pouch and
can be sent to the laboratory.
