free clinical study

convenient immunosuppressant adherence monitoring



The Mitra Microsampler class I medical device is for direct specimen collection of blood and other biological fluids. It is not specific to any clinical test, and is not for use in diagnostic procedures. Use of the Mitra Microsampler in Laboratory Developed Tests (LDTs) requires further processing including the establishment of performance characteristics and successful validation by the laboratory in a manner consistent with CLIA requirements.

At-home microsampling provides       transplant patients a convenient option for self-collecting and sending blood samples to the clinical lab. 


In this two-site study, four immunosuppressants in 36 patients were studied with the goal of measuring the correlation between standard wet blood sampling and dried blood microsampling.  

  • Consistent 10 µL blood collections
  • Simple protein precipitation clean-up
  • R2 values of 0.86 (site A) and 0.91 (site B)
