Sontra says wireless monitor accurately detects glucose changes

By Elaine Rigoli

Tampa, Fla., July 25 - Sontra Medical Corp. said a preliminary analysis of results from its glucose-monitoring trial demonstrated that the wireless glucose flux sensor accurately detected transdermal glucose to predict real-time changes in blood-glucose levels for 24 hours.

The primary goals of the study were to validate the design and operation of the wireless sensor and monitor system and collect data sets that will lead to the development of a blood-glucose prediction algorithm, the company said in a news release.

The Sontra Continuous Transdermal Glucose Monitor (CTGM) is being developed to monitor blood glucose of patients in the hospital intensive-care unit, the release said.

Sontra's CTGM system was tested on 10 healthy volunteers and 10 patients with type 1 and type 2 diabetes at an independent lab. The glucose-flux sensor signal was compared to finger-stick blood-glucose meter readings.

Currently, 320 data points from these patients are being analyzed to support development of the blood-glucose prediction algorithm.

Sontra is a medical-technology company located in Franklin, Mass.
