New Microfluidic Blood-draw Device Could Replace Needle Sticks and Venipunctures at Medical Laboratories

By placing this low-cost, disposable device developed at the University of Wisconsin-Madison on their arms or abdomens, patients can collect their own blood at home in minutes For more than two years, the nation’s media have been captivated by Theranos CEO Elizabeth Holmes’ vision of offering patients who need blood tests a finger stick collection instead of a venipuncture. Meanwhile, in research labs across the nation, there are credible efforts to develop ways to collect medical laboratory...

Detecting Cancer via a Patient’s Breath and Lasers

Here’s another paradigm-shifting innovation in diagnostic medicine! Researchers at the University of Colorado are using a patient’s breath and lasers to detect cancer and asthma (and possibly additional diseases in the future). The technology measures a patient’s breath by using mirrors to bounce a laser’s light back and forth until it has touched every molecule a patient exhales in a single breath. The laser can detect minute traces of compounds that are present when...
