The results of laboratory tests are used in many clinical settings. In the main, results obtained in point-of-care testing (POCT) are used either in monitoring or in diagnosis. Analytical quality does affect outcomes in these clinical situations. Numerical estimates of the quality required for laboratory tests to...

What quality is being controlled in laboratories today?  The definition of a quality requirement for each laboratory test is the starting point of quantitative quality management. Different types of requirements may be used as long as there are appropriate quality-planning models for translating those requirements...

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.

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...

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.

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...

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.

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 effects of carbon monoxide poisoning have been found to be greatly alleviated, or in some cases eliminated, through the use of hyperbaric oxygen therapy. This paper discusses the pathophysiology of carbon monoxide intoxication and presents an overview of its treatment.
