Delayed Diagnosis of Severe Hypoglycemia in a Septic Patient With Chronic Renal Failure.

Intensive Care Center, Medisch Spectrum Twente, Enschede, NLD.
High-dose vitamin C therapy has gained increased interest as an adjunctive treatment of septic shock, although convincing evidence is still lacking. High blood levels of vitamin C may interfere with several point-of-care blood glucose meters. We describe the case of a 67-year-old septic patient known with chronic renal failure who developed truly severe hypoglycemia, which was masked by spuriously high glucose values measured on a capillary blood glucose meter.

Summary: Measurement of glycated haemoglobin (HbA1c) has been utilised in assessing long-term control of blood glucose in patients with diabetes, as well as diagnosing diabetes and identifying patients at increased risk of developing diabetes in the future. HbA1c reflects the level of blood glucose to which the erythrocyte has been exposed during its lifespan, and there are a number of clinical situations affecting the erythrocyte life span in which HbA1c values may be spuriously high or low and therefore not reflective of the true level of glucose control. In the present case series, we describe the particulars of three patients with diabetes who had spuriously low HbA1c levels as a result of dapsone usage.

We evaluated the effect of haemolysis, bilirubin, lipemia, hyperglycemia and natremia on mean corpuscular haemoglobin concentration (MCHC) measured by XN 2000 (Sysmex). Our evaluation had shown than correction is necessary for haemolysis and lipemia but not for icterus. There were not possible to reproduce variation of MCHC with hyperglycemia or variation of natremia.

Finger stick blood glucose meters are widely used in outpatient and inpatient settings. However, various factors can affect accuracy of readings from these meters. Here we present a patient who had spurious glucose elevation on these meters while being on intravenous ascorbic acid.
