Oct. 28, 2005 -- The FDA and Abbott Diabetes Care are alerting doctors and patients about a possible problem with blood glucose meters made by Abbott Diabetes Care.

Abbott Diabetes Care, a branch of the company Abbott, isn't recalling the meters.

Patients may continue to safely use the meters, but they should check the unit-of-measurement display each time, says an Abbott news release.

If the meters are set to the wrong measurement unit, patients may misinterpret the meter's readings. That could lead them to mistreat their diabetes and possibly experience high blood sugar (hyperglycemia), a serious and potentially fatal condition.

Affected Products

The meters are sold under several names. In the U.S., Abbott's affected meters are:

  • FreeStyle
  • FreeStyle Flash
  • FreeStyle Tracker
  • Precision Xtra
  • MediSense
  • Sof-Tact
  • Precision Sof-Tact
  • MediSense
  • Optium
  • Private-label brands ReliOn Ultima, Rite Aid, and Kroger blood glucose meters

The meters are mainly available from doctors and through retail or mail-order pharmacies.

Affected models sold outside the U.S. are:

  • Xceed
  • Liberty
  • Boots
  • Xtra Classic
  • Easy
  • SofTrac

Test strips aren't affected, says Abbott.

Check the Display

The meters are designed to report blood glucose levels in two different measurements:

  • The U.S. standard, milligrams per deciliter or mg/dL
  • The foreign standard, millimoles per liter or mmol/L

"Users in the U.S. should make sure that their meter reading is displayed as mg/dL because an inaccurate reading can lead to taking the wrong dose of insulin or dietary changes, resulting in higher levels of sugar in the blood or hyperglycemia," says the FDA.

The meters can be accidentally switched from one measurement to the other, such as when someone is setting the meter's time and date.

"There also have been reports of the measurement being switched after a meter was dropped or after replacement of the battery. Abbott has not confirmed these additional causes of failure," says the FDA.

Need Help?

Unsure how to check the setting? Check the owner's manual, call Abbott Diabetes Care at (800) 553-4105, or check the company's web site.

If you think you may have been using the wrong read-out on your meter for a long time and are now worried about your health, contact your doctor, advises the FDA.

Your level is currently

If the level is below 70 or you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.

People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.

Congratulations on taking steps to manage your health.

However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.

Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.

Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.

One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
