| Title | Method Development and Validation for Dried Blood Spot Analysis based on Flow Through Desorption, Solid-Phase Extraction and Mass Spectrometry |
| Summary | Reduction of blood volume required for bioanalysis is of great importance for pharmacological data from pre-clinical studies and for animal welfare. Ideally, blood volumes taken should allow single-animal pharmacokinetic (PK) studies. For small animals such as rats and in particular mice, this is challenging, since only a few μL of blood can be withdrawn at every time point. In an earlier study we showed that small blood sample volumes could be collected on specially designed "sorbent sampling" cartridges and analyzed using a Spark Holland Symbiosis system.[1] The technique was successfully applied to record full PK data from single mouse. Recently, a new technology for online desorption of dried blood spots cards has replaced the sorbent sampling format.[2] In this work the results of a first evaluation of this new technology for very small blood volumes are shown. |
