When DBS cards debuted more than 50 years ago, they had significant advantages over traditional wet sampling, including simplicity, low cost, and ease of transportation.

Yet, adoption was hindered by regulatory concerns over the "Hematocrit (HCT) Effect" and automation limitations. In addition, incorrect spotting technique can lead to high sample rejection rates.

The FDA Class 1 Mitra® Microsampler is a remote specimen collection device that retains the advantages of DBS cards while overcoming their limitations.
