Technology Review - Metabolomx, a startup in Mountain View, California, recently completed a clinical trial that shows that its breath test can spot lung cancer with 83 percent accuracy and can also distinguish between several different types of the disease, something that usually requires a biopsy. The accuracy of the test matches what's possible with low-dose computerized tomography imaging of the lungs.
Colorimetric sensor array
The sensor is constructed on a simple plastic or paper like media. The sensor is inexpensive and disposable. The cost and performance easily match the requirements for a one time use medical exam. The CSA exam card used in the Metabolomx breath analysis instrument is printed on a plastic substrate, contained in a tube, through which breath can be passed. The exam card is disposable, one is used with each patient exam.
