Abstract

High concentrations of glycerol in plasma may result in overestimation of triglycerides in chemical and enzymatic assays. Known causes of increased glycerol concentrations in blood include glycerol-contaminated blood-collector tubes and pseudohypertriglyceridemia, a condition caused by genetic defects in the gene for glycerol kinase. We report a patient with sudden hearing loss who presented with an increased blood glycerol concentration after undergoing an oral glycerol test.
