[IP] SpectRx Continuous Glucose Monitor
Published Studies Show SpectRx, Inc.'s Continuous Glucose Monitor
Tracks Glucose Levels without the Need to Draw Blood
NORCROSS, GA (May 28, 2002) - According to an article
published in Diabetes Technology & Therapeutics (Vol. 5, No. 2),
laser-based glucose monitoring technology being developed by SpectRx,
Inc. (NASDAQ: SPRX) is capable of continuously measuring glucose
levels over a two-day period in people with diabetes without drawing
blood. Results of the studies also showed "excellent correspondence"
between blood glucose measurements and glucose readings taken using
the proprietary SpectRx technology.
"These study results are very encouraging and support our
vision that our painless technology for continuously measuring
glucose may one day replace painful finger stick tests," said Mark A.
Samuels, chairman and CEO of SpectRx, Inc. "We remain focused on
moving this technology toward commercialization due to its unique
potential to create value for the company in the estimated $4.5
billion dollar worldwide market for glucose testing."
The SpectRx technology measures glucose levels in transdermal
body fluid (TDF). TDF is the clear fluid under the skin through
which glucose and other nutrients travel from the blood stream to the
cells. The TDF is collected through an array of microscopic holes,
or micropores, created with a laser in the outer layer of skin, and
measured with a glucose sensor. The technology may be adapted to
measure glucose continuously or periodically. In addition to
glucose, other compounds found in the body may be measured with the
As presented in the article, more than 5,000 measurements
were taken on over 300 people in two separate studies. In both
studies, over 97% of the measurements were within the clinically
acceptable Clarke Error Grid A and B zones when compared to blood
readings. The time difference between the blood measurements and
readings using the SpectRx method was less than 15 minutes, with the
added benefit of minimal cosmetic effects when compared to drawing
blood through the use of lancets.
