If you’re diabetic and have been using GenStrip blood glucose test strips- stop now.

GenStrip blood glucose test strips, sold by Shasta Technologies LLC, may give incorrect blood glucose readings and should not be used, the US Food and Drug Administration (FDA) warned today. This recall was issued after extensive quality control violations were found during a recent inspection of the company.

Shasta’s GenStrip test strips are “third-party” blood glucose monitoring test strips not made by the same company as the meter with which they are used, the FDA noted in a safety communication.

These test strips are advertised for use with the LifeScan OneTouch family of glucose meters (eg, Ultra, Ultra 2, and Ultra Mini). The FDA recommends using alternative glucose test strips that are designed for use with the OneTouch family of glucose meters.

The affected test strips have been manufactured and distributed since March 2013 and are available through online retailers and retail pharmacies. The strips may be packaged in green and white packaging with the GenStrip name on top.
