Hourmozdi JJ, et al. - Authors performed an investigation to determine the prevalence of baseline abnormal lactate levels and to evaluate the effects of hemodialysis on serum lactate levels. Findings seemed helpful to providers in understanding the prevalence of abnormal lactate values in an outpatient end-stage renal disease population. A significant decrease in lactate levels was observed after hemodialysis. With this information, medical providers could interpret lactate values when patients with end-stage renal disease present to the Emergency Department.
