How do small labs cope with the demands of modern quality assurance? In this interview, Ruth Lock, head of the laboratory of the Anesthesiology and Intensive Care Dept. of the Copenhagen County Hospital in Glostrup, Denmark, tells how her lab keeps up with demands with the help of training and quality control.

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...

Two months of acclimatization to high altitude leads to an adaptation of the aerobic capacity of the myocardium, characterized by an increased ability to extract O₂ from the coronary vascular bed. An increased mitochondrial volume and activity of oxidative enzymes or improved diffusion conditions could be involved.

An altitude of 5,000 meters above sea level or just above is just about what humans can bear - be it during an acute ascent or for permanent living. This study describes how bodily functions of crucial importance to survival at high altitude adjust after abrupt exposure to severe hypoxia.

Providing continuous technical support and reliable test data collection for point-of-care blood gas testing is a difficult task for many laboratories.  Here we describe how the implementation of an integrated instrument control and data management system for point-of-care blood gas testing has streamlined these...

Examination of peripheral pulses and peripheral blood pressures are commonly used methods for investigation of macrocirculation. However, falsely elevated peripheral blood pressures may complicate the accurate prediction of ulcer healing in diabetic patients.  Because tcpO₂ also measures the nutritive skin capillary...

How relevant is transcutaneous measurements in the detection of critical limb ischemia?  Acutecaretesting.org has asked a group of respected researchers and clinicians in the US and Europe to describe how they use transcutaneous measurements in their daily work.

Point-of-care testing (POCT) is a delivery option for performing laboratory testing closer to the patient. Due to increasing healthcare pressures for faster turnaround of laboratory results and the development of a broader menu of testing devices, POCT is growing in popularity. Devices today are more portable,...

The pro-con debate on the advisability of introducing POCT deals with the likely clinical benefits but – to an even higher degree – with the economic aspects. We discuss various models for determining the costs, and some caveats.
