This is the second of two articles focusing on the reference interval, the most widely used tool for interpretation of patient test results.  The first [1] was an introduction to the theoretical concepts that underpin the significance, construction and use of reference intervals. Here consideration is given to the...

As point-of-care applications of lab testing demand more rapid and clinically integrated order entry and results-reporting processes, it becomes paramount for the laboratory to investigate entire clinical processes. Direct observation and process mapping of these clinical applications – end to end - are "lean" tools...

Applications of point-of-care testing (POCT) for diagnostic biomarker measurement in healthcare have increased significantly in recent years in a wide range of clinical scenarios. These include infectious disease, critical care, cardiology and other areas of emergency medicine. Traditionally, routine clinical...

Timely and accurate diagnosis of sepsis is of great importance for the choice of treatment, level of monitoring and prognosis. For this biomarkers could be a significant aid, and thus the search for and application of sepsis biomarkers are of great importance.  Current evidence suggests that C-reactive protein and...

The population-based reference interval is the most widely used tool for interpretation of individual patient laboratory test results. The clinical value of those results depend crucially on the reference intervals with which they are compared, and all efforts directed at ensuring analytically precise and accurate...

All clinical procedures and treatments are associated with potential adverse effects of greater or lesser significance.  The undisputed value of blood testing for both diagnosis and monitoring of disease is tempered by the recognition that repeated blood sampling can result in blood loss of sufficient magnitude to...

It is estimated that a majority of all laboratory medicine errors are errors that occur during the preanalytical phase of the laboratory testing cycle. Such errors have a significant impact on patient safety, staff workload, and hospital costs.  Correctly identifying patients and avoiding specimen-labeling errors are...

With the use of a new Data Management System (DMS) software program [1], the majority of Point Of Care Testing (POCT) equipment throughout the Waikato District Health Board region has been connected to the Laboratory Information System (LIS) and the Hospital Information System (HIS). Prior to the new DMS, viewing...

Maintaining lasting progress in laboratory test utilization is difficult to do without a reminder tool for providers. Since implementation of a quarterly physician report card in 2003, we have seen sustained improvement in the ordering of wellness tests in an ambulatory care network in the United States for over four...

Modern analytical devices for testing biological fluids, such as blood, have now developed a sophistication that ensures the quality of the analytical result is capable of matching that achieved in the central laboratory.    Complementary developments are focused on reducing operator-related and connectivity-related...
