FDA warns of faulty results with blood sugar tests
By MATTHEW PERRONE (AP) – 7 hours ago
WASHINGTON — The Food and Drug Administration is warning diabetes patients that certain blood sugar tests can give inaccurate results in patients taking other medications.
Public health regulators told consumers on Friday not to use certain glucose testing strips from Roche, Abbott Laboratories and other companies in combination with dialysis and other biologic drugs. According to FDA those formulations contain non-glucose sugars, which can falsely elevate blood sugar results and increase the risk of insulin overdose.
People with the disease often have to inject insulin, which helps break down carbohydrates, because their bodies have become resistant to the protein.
Dialysis and so-called immunoglobulins are most often taken by patients with serious medical ailments, including kidney failure and rheumatoid arthritis. The biologic drugs' labeling already warns that they can interfere with glucose monitoring tests, but FDA says the products continue to be used together despite past warnings.
Since 1997 the FDA received 13 reports of death related to the use of glucose testing strips and biologic drug formulations.
"Six of the deaths have occurred since 2008 despite FDA's efforts to communicate the risk," the agency said. In some cases, patients experienced brain damage, coma and confusion before death. In a letter issued Thursday, the agency urged doctors and nurses to report any suspected problems related to glucose strips.
Many of the testing strips are used in hospitals and nursing facilities, "which should instead use a laboratory assay to measure a patient's glucose if the patient is also receiving an interfering product," the FDA said in a statement.
Brands affected by the announcement include Roche's Accu-Chek Comfort Curve test strips and Abbott's Freestyle test strips.
A spokesman for North Chicago-based Abbott said the company has been working on a new version of the Freestyle that addresses the problems cited by the FDA. Abbott expects to submit a marketing application for the new product to FDA in the next 30 days.
Calls to Swiss manufacturer Roche were not immediately returned Friday evening.

OK, so what are patients suppose to do if they don't want patients to use any of the glucose testing strips? This is sort of a bad warning because most diabetics now days use a sliding scale of the amount of insulin to use regarding blood sugar compared to when I was diabetic and the dosage was set with no change if one had high or low blood sugar. This should have been a warning and the FDA should work with the glucose meter companies to come out with new meters and strips to have beter testing capabilities.
FDA should not have singled out the two companies and should have listed the other companiesthat are just as big as Abbott and Roche in making glucose meters.
