PCT levels were correlated with the severity of disease at onset (APACHE II) and inflammation (CRP) but not with Ca2+ levels. Inaugural PCT or CRP levels per se poorly predicted outcome but decreasing levels were associated with a higher probability of survival. In this respect, PCT was found to be an earlier marker than CRP.

We report age-related reference intervals for capillary zone electrophoresis for children between 1 and 14 years of age.

Circulating myoglobin is recognized as an early and sensitive marker of acute coronary diseases. Long turnaround time of myoglobin assays jeopardize their clinical utility. We evaluated the analytical performance of the Stratus CS fluorometric enzyme immunoassay based on dendrimer technology, and claimed to achieve a fast and reliable determination of plasma myoglobin concentrations. Precision complied with the recommended analytical performance criteria. Method comparison and recovery experiments indicated, that despite good between-method correlations, the Stratus CS method overestimated myoglobin concentrations in comparison with values obtained on Cobas Integra 400 and BN A. However, since the manufacturers' cut-off for elevated plasma myoglobin levels was higher for Stratus CS than for other techniques, few discrepant results were observed between methods. Elevated levels of hemoglobin, triglycerides and rheumatoid factors did not interfere in the Stratus CS method but hyperbilirubinemia caused a positive difference.
