DBS provides whole blood dried on a paper or polymer device. The blood is usually collected from the fingertip or heel of humans or from the hind leg or tail of experimental animals. Blood collected by venipuncture can also be deposited on such devices and become DBS samples.
Vitas has developed and validated assays for DBS samples during the last 15 years and our portfolio of markers are now extensive and grows continuously. We provide biomarker analysis from DBS to academia, biotech, pharma, and private companies as marketing tools.
The perhaps greatest benefit from using DBS, is the power of simple and inexpensive sample collection. Kits for collection can be produced white label from 1000 to several hundred 1000 and distributed very efficiently at low price to participants at home via the mail system. Samples (a few drops of blood) collected at home by the participant and without assistance from health personnel. The DBS sample is returned to the study center or directly to the laboratory for analysis. Results can be transferred to sponsor by safe protocols like sFTP (secure file transfer program), API (application programming interface), or visualized in an app or webpage directly to the consumer using exclusive codes. As an example, Vitas provided DBS kits and analytical services as well as on-line reports for the National covid-19 IgG antibody screening in late 2019/2020. 30 000 samples were submitted, analyzed and reported in 1.5 months. The study is published here (follow this link).
