New Microfluidic Blood-draw Device Could Replace Needle Sticks

Tasso is revolutionizing diagnostics by creating technologies for blood sample collection that place the user at the center of process. Our wearable blood collection system, the HemoLinkTM, is being developed to improve the user experience as well as enable both healthcare consumers and providers with convenient access to reliable laboratory test results.

In a process known as “capillary action,” HemoLink leverages microfluidics to create a slight vacuum that pulls blood from capillaries though tiny channels in the skin into a small tube, noted a Gizmag report. The device collects 0.15 cubic centimeters of blood, which is enough to test for cholesterol, infections, cancer cells, blood sugar and other conditions.

Pathologists and clinical laboratory professionals will be watching the eventual launch of HemoLink to learn how its developers have overcome the problems affecting lab test accuracy that can be caused by the interstitial fluid that often accompanies capillary blood when such specimens are collected. How the lab test technology used by Theranos addresses this same problem has been an ongoing point of interest among medical laboratory professionals.
