Volumetric absorptive microsampling (VAMS®) is used for remote collection of capillary blood or other biological fluids. A sample of less than 50 µl blood is collected, dried and sent via regular mail to a central laboratory for analysis.
This technology is similar to the dried blood spots technique that has been used for more than 40 years, yet has a few significant advantages, such as a more simple, user-friendly dried blood collection approach. VAMS® has the potential to reduce analysis costs and number of clinical visits and may be used to monitor study drug adherence.
At CTC, we look forward to implementing the VAMS® technology in more clinical trials in the future. The method is perfect for virtual clinical trials but may be used for at home sampling in most trials.
