THURSDAY, Dec. 10, 2015 (HealthDay News) -- Many Americans with type 2 diabetes may be getting unnecessary tests -- and, in some cases, needless changes in medication, according to a study published online Dec. 8 in The BMJ.

The study's findings are based on insurance claims made between 2001 and 2013 for 31,545 type 2 diabetes patients age 18 and older. All of the adults in the study had glycated hemoglobin (HbA1c) levels that were consistently below 7 percent within the previous two years.

Nearly 55 percent underwent HbA1c tests three or four times per year. Another 6 percent had at least five tests per year. Frequent HbA1c tests were also associated with increased odds that patients would be started on additional medications to control their glucose levels.
