Dried Blood Spot Collection Device


OHSU # 1810

Technology Overview:

In current Dried Blood Spot (DBS) sampling, poor technique can result in uneven concentrations across the material, which may lead to errors in analysis and unusable samples.


Additionally, many DBS sampling approaches rely on patients and/or clinicians to perform multiple steps that may be cumbersome, or may require disposal of blood collection materials as hazardous waste.  This device is a self-contained, easy-to-use, and safe method for obtaining a DBS sample which can be used for either qualitative or quantitative analysis.


Compared to clinical blood collection approaches such as venipuncture, this technology will reduce costs and decrease impact on the user. The device may be used remotely and then mailed to a clinic, providing cost savings from travel, fewer points of contact, and decreased barriers to compliance.
