Rationale:
- Generally, random plasma glucose levels are not considered diagnostic and should not serve as a screening test for type 2
diabetes; however, in instances in which patients are found to have elevations in random plasma glucose levels, further testing
for diabetes may be warranted.
|
|
Evidence:
- Patients with mild-to-moderate elevations of random blood sugar (glucose >126 mg/dL but less than the diagnostic 200 mg/dL)
are at elevated risk for developing overt type 2 diabetes (54); these patients might have impaired glucose tolerance or impaired fasting glucose (55).
- Furthermore, the risk of microvascular complications is associated strongly with elevated blood-glucose levels (22).
|
|
Comments:
- Because of the elevated risk and increased likelihood of benefit in this population, periodic monitoring for the development
of diabetes might be warranted.
