What Is Microsampling & How Does It Work?

GX Sciences takes extra measures and cutting edge technology to make diagnostic blood testing more accessible, time saving and accurate.

In conventional diagnostic blood testing, blood is drawn from a needle inserted in to a vein into tubes that typically range from 4mL to 10mL. This venipuncture procedure requires a phlebotomist, which in turn requires customers to visit centralized draw station with large waiting rooms and long wait times.

In order to bring diagnostic blood testing to providers’ offices or a patient’s home, GX Sciences Mitra microsampling device offers new collection technology which is designed to:

  • Collect capillary blood from the fingertip instead of blood from a vein in the arm
  • Captures & analyzes minute samples of blood for analysis and is performed by a simple finger prick, allowing a blood droplet to be absorbed to the Mitra collection device.
  • Samples are held in a plastic protective case and can be mailed to laboratories without the need of refrigeration or special handling.
  • Allow the patient or provider to collect the blood sample quickly or from the comfort of a patient’s home
  • Blood microsampling allows participants to draw their own blood and mail to our lab for analysis and offer much of the world's population that lives in remote areas the ability to provide their blood sample results to a medical provider anywhere.
  • Enhance the telemedicine providers care by offering patients who prefer online or phone consults the ability to have bloodwork ordered and a microsampling kit delivered to the patient's home to submit a sample to our lab and the results to their provider.

Diagnostic blood testing usually requires venipuncture because capillary blood collection presents a range of obstacles to sample quality. In order to collect capillary samples with high enough quality to produce diagnostic results, GX Sciences new collection technology is designed with:

  • Controls to reduce sample contamination
  • Controls to reduce clotting during extraction
  • Controls to reduce damage to red blood cells


Blood belongs in your body, not in a medical waste bin.

In conventional diagnostic blood testing, more than 95% of the blood is discarded and never analyzed. We are using sample handling technology designed to reduce the amount of blood that is wasted by over 90%.
