Clinical Significance

Clinical Significance

Glucose

A fasting glucose level ≥ 125 mg/dL indicates the presence of diabetes mellitus, associated with a significantly increased risk of developing CVD, stroke, peripheral vascular disease, kidney failure, neuropathy, and retinopathy. The test needs to be confirmed by also having an elevated HbA1c level. Clinically significant hypoglycemia is defined as blood glucose <54 mg/dL.1
