Blood plasma samples are obtained from type 2 diabetes (T2D) patients and a concentration of F2-isoprostanes (F2I) in the sample is quantified. Plasma F2I levels assess oxidative stress levels in the patient and indicate elevated risk of T2D-associated complications including incident clinical fracture, cardiovascular complications, renal disease, etc. in the T2D cohort, independently of other risk factors. Fracture risk in the T2D population is heightened for a given bone mineral density (BMD) and is underestimated by evaluation tools such as Fracture Risk Assessment Tool (FRAX). The patient's BMD T-score can be adjusted based on F2I concentrations, capturing reductions in bone quality as well as quantity that lead to the elevated fracture risk in T2D patients. These diagnostic procedures can be effectively deployed in a patient's course of treatment merely by supplementing an existing blood panel, rather than with a separate blood draw.
