Capillary plasma separation microsampling devices

Dried blood spot (DBS) testing has gained significant popularity in the field of bioanalysis, particularly in therapeutic drug monitoring applications. A PubMed search using the term "dried blood spot testing", restricted to 2002–2012, produced 99 results, whereas a search for 2013–2022 resulted in 1094 results.

These devices represent a step forward for the more widespread application of capillary microsampling in laboratory medicine, facilitating the prediction of plasma/serum concentrations after the collection of capillary blood.
