Preanalytical errors are said to be the reason for up to 75 % [1] of all errors in laboratory medicine. The diagnostic consequences depend on the magnitude of the preanalytical error.  In worst case, these errors may lead to mistreatment of patients; in all cases, these errors are an extra workload for the hospital...

Non-invasive monitoring of oxygenation has become a standard procedure in neonatal critical care. Both transcutaneous pO₂ (tcpO₂) monitors and pulse oximeters involve methodological and practical issues that should be known to those using these devices in infants. tcpO₂ measurements are influenced by skin thickness, ...

Since Meakins in 1927 described the relationship between increased blood lactate levels and the presence of oxygen debt (tissue hypoxia) in patients with circulatory shock [1], lactate levels have been used to diagnose and monitor the treatment of these patients. However, as lactate is a normal (end) product of...

According to the Hvidovre Hospital, standardizing is a must if POCT is to run optimally. In the first article of the series "POCT setups for blood gas", acutecaretesting.org interviews the Danish hospital on how they have successfully implemented POCT.

In conjunction with Apgar scores and other parameters, umbilical-cord blood gas values are used to assess newborn respiratory status.  Paired umbilical-cord gas venous and arterial samples were collected from 200 patients to establish reference ranges for blood gas/hemoximetry parameters. Umbilical-cord samples were...

Both high and low blood glucose levels may be dangerous to the newborn baby. Measurement of blood or plasma lactate concentrations gives an indication of the adequacy of oxygen delivery to tissues, and blood and CSF lactate levels are essential investigations in the diagnosis of inborn errors of metabolism (IEM)....

Babies are not small adults! The potential for abnormal adaptation to life outside of the womb, changes in physiology, and a myriad of possible life-threatening clinical conditions requires an understanding of the laboratory tests needed to support these infants.  To effectively handle the unique needs of these...

Neonates are subject to more preanalytical influences than any other population group. Many of these are related to the maturity of the infant and its adaptation to extra-uterine life. The necessary need for capillary blood collection and processing of small quantities of blood introduce additional preanalytical...

While analytical quality standards seem well established, there has been a paucity in the development of such standards for the preanalytical phase.  Technical recommendations regarding sampling, transport, and identification have been developed in national (NCCLS, DIN) and international (IFCC, ISO) consensus...

60 % of all neonates develop jaundice during their first week of life and thereby run a risk of getting hyperbilirubinemia.  Although different approaches for establishing treatment criteria have been suggested, treatment of neonatal hyperbilirubinemia is usually still based on the measurement of total bilirubin...
