The Food and Drug Administration (FDA) issued a warning to the diabetic patients that those who were taking other medicines may have inaccurate blood sugar tests.

Certain glucose testing strips from Roche, Abbott Laboratories and other companies in combination with dialysis and other biologic drugs have not been recommended by the public health regulators.

13 reports of death have been reported to the FDA since 1997, related to the use of glucose testing strips and biologic drug formulations.

Insulin is a popular drug used by diabetic patients to help break down the carbohydrates as their bodies are resistant to the protein. Dialysis and other immunoglobulins are very frequently taken by kidney and arthritis patients.

Although the biologic drugs' labeling clearly warns that the consumption of these can interfere with glucose monitoring tests, but their use is being continued, says FDA.

Roche's Accu-Chek Comfort Curve test strips and Abbott's Freestyle test strips are the prime brands affected by this announcement.

Abbott informed that the company has started working on a new version of their product following the FDA's warning. It is expecting to submit a marketing application to the FDA in the next 30 days. Roche, on the other hand did not respond promptly to this announcement by the FDA.
