GlycoMark®, Inc. Announces Agreement with PrismHealthDx, Inc. to Expand Diabetes Test Panel with the GlycoMark Test

Posted on November 7, 2018 by

New York, NY (November 7, 2018)— GlycoMark, Inc. and PrismHealthDx, Inc. (PHDx) have announced an agreement to offer the GlycoMark® test to clinicians managing patients with diabetes.  The GlycoMark test is the only FDA-cleared blood test for patients with diabetes that is specific to detecting recent hyperglycemia and hyperglycemic excursions (occurring while fasting, postprandial, or both).  As part of this agreement, PHDx is now promoting and offering the GlycoMark test to its network of physicians through its laboratory services organization.

Recent hyperglycemia (elevated blood sugar levels) and hyperglycemic excursions (blood sugar spikes) can go undetected with routine tests and put the patient at risk of diabetic complications including kidney disease, vision loss, amputation, heart attack and stroke. Nearly 40% of patients who are deemed to be in “good control” based on the A1C, a 3-month glucose average, may still have significant postprandial hyperglycemia or glycemic variability. Furthermore, a periodic blood glucose test is not always reliably timed or performed, and may yield inaccurate results.

“The GlycoMark test helps detect glycemic variability that is not evident with A1C,” says Hiro Ishibashi, President of GlycoMark. “Our agreement with PHDx increases physician awareness and access to the GlycoMark test to so that patients at risk of significant diabetes complications can be more closely managed and treated.”

“By integrating GlycoMark into our test menu, we are demonstrating our commitment to provide our clinicians, and their patients, access to important clinical technology focused on lowering cardiovascular risk and improving the care of patients with diabetes,” says Jim Canfield, President and CEO of PHDx.
