Lack of Benefit of Routine Serum Laboratory Control Samples during Treatment of Diabetic Foot Infection

Purpose: Clinicians often routinely order measurements of serum inflammatory and other laboratory markers to assess the response to treatment of diabetic foot infections (DFI). Scientific evidence supporting this widespread practice is very limited and unclear. We sought to determine if the levels (or their dynamic change) of these markers predict important future outcomes, including recurrence of infection and development of foot ischemia
