Eighteen months before transplantation, the serological profile suggested a recent EBV primary-infection, four months before transplantation, we had isolated anti-EBNA IgG and five days after transplantation, the serological profile suggested a past infection. All EBV PCR performed on whole blood were negative. Retrospectively, immunoblots anti-EBV IgG were performed. Blots showed no anti-EBV IgG before and until the day of liver transplantation. Five days after transplantation, slight bands of both IgG anti-p18 (VCA) and anti-EBNA-1 were found, without any other serological marker.

Acute pancreatitis was then diagnosed according to a plasmatic lipase more than tenfold normal values associated with a severe hypertriglyceridemia superior to 100 mmol/L. The triad composed of diabetic ketoacidosis-acute pancreatitis-hypertriglyceridemia is rarely found in childhood and can have deleterious consequences.

Ten sample pools were prepared and separated into six aliquots. These aliquots were overloaded with hemolysis in increasing amounts to reach levels equivalent to the maximum hemolysis thresholds H1 (+), H2 (++), H3 (+++) and H4 (++++). Each aliquot is compared to its reference aliquot (not hemolyzed) and a ratio is calculated for each parameter. We proposed that there was a significant difference if, for a given analyte and threshold, more than 20% of the ratios are above the total acceptable limit variability. A significant difference was found for TGP, TGO, cholesterol, creatine kinase (CPK), lactate deshydrogenase (LDH), phosphorus and potassium at H1 (+), chlorine, iron, γ-glutamyltransferase (GGT), and magnesium at H2 (++), amylase and alkaline phosphatase (PAL) at H3 (++++), and prealbumin at H4 (++++). No interference was found until H4 included for uric acid, calcium, creatinine, lipase, glucose, HDL-cholesterol, triglycerides, urea, sodium and immunoglobulins A, G and M. The overestimation of kalemia was calculated as a function of hemolysis, ranging from 0.28 mM +/–0.047 (upper H1 threshold) to 1.37 mM +/–0.126 (upper H4 threshold). Its estimation makes it possible to propose a result rendering algorithm of kalemia according to the hemolysis index.
